April in the Garden in the Santa Cruz Mountains

Spring might have officially started mid-March but judging from the wonky weather it’s hard to tell. We did experience a ?Miracle March?? with a pretty good dose of needed rainfall along with some very cold weather. You never know what to expect in March around here.

But now we?ve turned the corner on spring with flowers bursting open within hours on these nice days. The Black-headed grosbeaks have returned to my yard for the breeding season. Like clockwork they show up on almost the exact day each year. It?s my version of the swallows returning to San Juan Capistrano.

Looking forward to the rest of spring, here?s what I?ll be doing around here in April.

Hopefully we?ll have plenty of April showers. This latest rainfall is surely? welcomed. One of the perks of a cool, rainy spring is that shrubs and perennials have longer to establish a good root system before hot weather arrives, ground covers have time to spread and shade the soil, conserving moisture come summer. What strategies can you follow that will make your garden low maintenance this summer and give you extra time to enjoy it?

Plant in masses. When designing or reworking your garden, make it

ajuga reptans, a groundcover for shady spots

easy on yourself by planting fewer varieties but in greater numbers. Planting this way will reduce the number of different maintenance tasks for that area. For example, if you have a large hillside that you want to cover, plant it with a groundcover like ceanothus gloriosus which fans out 6-15 feet. Some manzanitas like arctotaphylos uva-ursi eventually spread to15 feet each. Sage leaf rockrose and germander are also good for sunny areas. A shady spot could be planted with ajuga, creeping mahonia or Walkabout Sunset lysimachia.

Another time saving strategy is to group plants with similar moisture needs. This may sound like a no brainer but if you have just one prima donna in a bed of more drought tolerant plants, you’ll be dragging the hose over to that bed for just one plant or having to run your irrigation system more for it. If you find that some of your plants are not quite as low water as you’d like, move those to their own spot. In general, plants with large leaves usually require more water and transpire faster while drought tolerant plants typically have one of more of the following characteristics: deep taproots and leaves that are smaller, silver, fuzzy or succulent.

ceanothus ‘Carmel Creeper’ – A low maintenance, low water groundcover for sunny spots

Avoid putting thirsty plants in hard-to-reach places. If the irrigation system doesn’t reach that far, keep it simple by planting drought tolerant woody shrubs or perennials there.

Pluck weeds when the soil is moist and before they have gone to seed. Even if you don’t get the entire root of more persistent weeds, just keep pulling at the new growth. Eventually, the plant will give up having used up all of the food stored in its roots. I?m still battling hedge parsley with it?s sticky seed balls that will cling to my shoelaces and the dog?s fur if I don?t get it before it sets seed.

Plant edibles among your other plants near the kitchen. Tricolor sage looks great alongside other plants with pink and violet leaves. Purple basil planted below the silver foliage of an artichoke is another great combination. Lemon thyme growing next to a burgundy colored dwarf New Zealand flax would look spectacular, too. And don’t forget to plant decorative and delicious Bright Lights swiss chard with its stalks of yellow, orange, pink, purple, red, green and white throughout your beds. It?s one of the easiest vegetables to grow.

So get the lemonade ready to enjoy all your free time later this season.

The Beauty of Fall

Looks like Indian Summer is over and fall is really here. The trees, especially our own Big Leaf Maples, are showing off their new fall clothes and the rains will soon green up the hills. Will the foliage be as vivid this year?

Cercis ‘Forest Pansy’

Although we don?t get as much fall color as other areas we enjoy what we have just as much. Besides we don’t get snow on Halloween. Enjoy these cool nights and warm days. That?s the combination that brings on the best fall colors.

The vivid colors in a leaf are always there. They are just masked by the green chlorophyll which is busy making food by photosynthesis while the sun shines. Come autumn, shorter days and cooler temperatures cause the trees to switch into energy-storage mode and their leaves stop producing chlorophyll. For the few weeks before the leaf falls to the ground it is colored only by natural pigments. It’s these colors -red and purple anthocyanins, yellow and orange carotenoids – that make fall foliage so glorious, sometimes anyway.

Quaking aspen- Wyoming

Weather conditions play a major part in fall color. Some years the show is more dramatic than others. The best conditions for intense leaf color to develop are dry sunny days followed by cool, but not freezing, nights.

A warm, wet autumn will almost surely result in less-than-spectacular foliage because the process of chlorophyll loss will be less consistent. Freezing temperature meanwhile can cause leaves to drop suddenly denying the opportunity to enter a slow, colorful dormancy.

Which plants put on the best show in our area? Here are some of my favorites.

California native Western redbud turns yellow or red in the fall if conditions allow. This plant is truly a four-season plant starting in spring with magenta flowers, then leafing out with apple green heart shaped leaves. Colorful seed pods give way to fall color. This small native tree or large shrub does well as a patio tree in gardens with good drainage.

Other native plants like spicebush and Western azalea turn yellow or gold in the fall. A native vine that lights up with the onset of autumn is Rogers Red California grape. If you have an arbor, wall or fence that needs covering quickly this is your plant. The green and gray leaves are transformed in autumn into great draperies of rich, scarlet leaves with clusters of summer fruit turning all shades of purple.

Edibles that turn color in the fall include blueberries, pomegranate and persimmons.

Other trees and shrubs that do well in our area and provide fall color include Chinese flame tree, ginkgo, Idaho locust, Chinese pistache, crape myrtle, witch hazel, all maples, liquidambar, katsura, dogwood, locust, cherry, crabapple, oakleaf hydrangea, barberry and smoke tree.

Now through late fall is a good time to shop for trees that change colors because you can see in person just what shade of crimson, orange, scarlet or gold they will be. I’m off to the the Sierra to see for myself the dogwood, cottonwood, willow, black oak and quaking aspen in fall color. What?s not to love about fall?

California Natives for Erosion Control

Who knows what the weather will be like this winter but what we do know is that some of our rain events will come with a vengeance. It’s not that unusual for our area to get 8 inches of rainfall during a storm and that can create havoc on an unprotected hillside. Fortunately, October is a good time to do something about it.

Pink Flowering Currant

Fall is the perfect time to plant in our area. The soil is still warm encouraging root growth and the weather is mild. Using the right plants on hillsides can help slow and spread runoff and prevent soil erosion. Mulch also protects soil from direct rain impact and slows runoff across bare soils. Covering the steepest slopes with jute netting through which plants may be installed is an added precaution.

There are many attractive plants that work well for erosion control. Often they need to adapt to shallow, poor soil and cope with less than ideal conditions all while putting down dense, strong roots. California natives are well suited to this job.

Common native shrubs include ceanothus and manzanita of all

Calycanthus occidentalis

types. Calycanthus or Spicebush has fragrant flowers in late spring blooming well into summer with a spicy fragrance. The foliage is aromatic when crushed and changes from a spring green color to pale golden in autumn. Decorative woody fruits last into winter making this shrub attractive year round. It thrives with infrequent to moderate watering. Combine with coffeeberry and deer grass in sunnier spots or with Douglas iris and giant chain fern in shaded spots below trees. All these plants have deep roots and control erosion.

Ribes s. King Edward VII

Ribes sanguinem or Flowering Currant is another show stopper capable of controlling erosion. In the spring the long, flower clusters of this deciduous shrub will dominate your garden. Choose from white flowering ‘White Icicle’ or ?Barrie Coate” and ‘King Edward VII’ with spectacular deep red flower clusters. ‘Spring Showers’ has 8 inch long pink clusters. Grow in full sun to partial shade. This California native requires little water once established and is a valuable nectar source for hummingbirds.

Some other good California native shrubs for erosion control are western redbud, mountain mahogany, western mock orange, lemonade berry, toyon, matilija poppy and western elderberry. ribes viburnifolium, creeping mahonia and baccharis. Ceanothus maritimus, ?Heart?s Desire? and ?Anchor Bay? are all good groundcover selections and are not attractive to deer.

Symphoricarpos – Common Snowberry or Creeping Snowberry – can hold the soil on steep banks. This native tolerates poor soil, lower light and general neglect.

Smaller natives that put down deep roots are yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage and salvia.

Bush poppy -dendromecon rigid- is another native found right here in our area and needs no irrigation at all once established. Beautiful bright yellow, poppy-like flowers cover the plant in spring. They can be propagated from cuttings taken in summer and are pest and disease free.

Remember when setting plants on a steep slope to arrange them in staggered rows. Make an individual terrace for each plant and create a basin or low spot behind each one – not around the stem – to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.

 

Shady Garden Success Stories

If you read my column regularly or even once in a while you?ve probably heard me lament about the difficult growing conditions here in my garden. Between the sandy soil, 5 hours of intense sun but for only 6 months of the year, gophers, squirrels, moles, deer and chipmunks I?m happy if any plant thrives. So it is with pleasure that I report to you the small successes I?ve had lately and maybe give you hope that you might also grow plants that provide some color and fragrance in your garden along with attracting hummingbirds, songbirds, bees and butterflies.

As the sun shifts lower in the sky, my garden becomes shadier each day. The soil is still warm, however, and that encourages root growth so even though I won?t see much happening above ground until late next spring hope springs eternal and I am driven to plant more natives as well as other appropriate plants that will fill in those blank spots.

Gaura l. ‘Siskiyou Pink’

This week a clump of deep pink gaura lindheimeri is blooming like crazy. If I had my druthers I wouldn?t have planted it among a stand of orange flowering California fuchsia but it still looks great against the gray foliage of the epilobium or zauschneria or whatever it?s called now days.

Gaura ?Siskiyou Pink attracts butterflies and hummingbirds and needs only occasional water. The books will tell you gaura requires full sun but mine is thriving without a lot of sun. Don?t be afraid to try a plant you like despite what the books tell you.

Zauschneria aka epilobium

Same goes for the light requirements of the California fuchsia. Mine is happily spreading and it gets only partial sun for part of the year. Las Pilitas nursery website, a great source of information, does say they will tolerate part-shade and commonly grow where there is extra moisture in the winter and spring, gradually drying through fall. Guess that 140 inches of rainfall I got up here in Bonny Doon last winter would fall into that category. As far as the renaming of plants California fuchsia apparently is now called epilobium canum but the name zauschneria may come back so call them whatever works for you.

One of these days I want to plant a few more native plants that will tolerate shade and attract wildlife. Toyon with it?s red berries is high on my list as is Pacific wax myrtle. I have a pink flowering currant which is doing well as well as sambucus mexicana which the hummingbirds, jays and chipmunks like and a Black Lace elderberry.

Sambucus ‘Black Lace’

Of course, all the different ceanothus do well in partial shade, grow fast and the birds and bees love them both in bloom and now that they are full of berries and seeds. My covey of quail find the berries irresistible. Apparently porcupine like them also but fortunately for my dog, Sherman, I don?t have any of those.

California native Pacific Coast Iris, Woodland Strawberry, Heuchera maxima, Western Columbine, Bleeding Heart, Mimulus and Wild Ginger all do well in my lean, shady, sandy soil. For some reason I don?t have any any coffeberry or any Oregon Grape but they are both on my wish list. Coffeeberry is one of the best all around native plants for wildlife and mahonia or Oregon Grape bloom in the winter and provide much needed nectar for hummingbirds.

Interesting Plants to Update your Garden

Tired of seeing the same plants in your garden and everywhere else? Feel like changing things up a bit? With this question in mind I?ve turned to my fellow landscape designers to see what plants they are using these days so that every garden they design doesn?t look the same. You can have too much of a good thing.

One thing I know for sure is that I don?t want to recommend a plant that hasn?t been shown to be a reliable grower in a variety of conditions. Sometimes the latest and greatest plant introduction turns out to be a dud. Other times a new cultivar of an old favorite hits a home run. Here are some oldies but goodies and new plants to add to your garden.

 

Loropetaum ‘Jazz Hands Dwarf PInk’

Loropetalum ?Jazz Hands? is getting the nod from everyone who?s grown it. If you love the deer tolerance, low maintenance. moderate watering and toughness of regular Chinese Fringe Flower this showy dwarf variety is even easier to grow. Staying low and tidy Jazz Hands Dwarf Pink has cool purple foliage with a cranberry undercurrent and hot pink blooms. It looks great combined with Jazz Hands Dwarf White. Local wholesale nurseries are growing it so it?s readily available.

Speaking of local sources for plants, we live in one of the prime growing areas for landscape plants. I recently learned that one of my favorite plants Canyon Snow Pacific coast iris is going through a difficult time. Seems it?s become less vigorous than the other colors in the Canyon series and the growers are working to improve their stock. We need to count on a plant?s performance. There?s enough other issues to deal with in our gardens without starting with a wimpy plant.

Cistus variegata ‘Mickie’

Rockrose have always been favorites in the low water use garden. There?s one with a low, mounding habit that hugs the ground and creates a super colorful accent to the sunny garden. With brilliant gold leaves splashed in the center with green this variegated cistus hybridus called ?Mickie? is hardy in winter, grows only 14-18 inches tall and spreads to about 2 feet wide. Perfect for containers or smaller gardens.

If you like to include California native plants in your garden Woolly Blue Curls or trichostema lanatum has been shown to be reliable in the garden if given full sun, good drainage and little fertilizer or amendment. Group similar plants and forget about them. They bloom from late spring through summer and make a good cut flower. Another common name for this plant is Romero or California Rosemary which dates back to the Portola expedition in 1769.

If you want to make a big splash in your garden or container try growing Salvia ?Amistad? or Friendship Sage. With fast growth in the warm months to 4 or 5 feet tall, the rich royal purple flowers attract hummingbirds and butterflies to the garden. It will grow in light shade with medium water requirements and remain evergreen in warmer parts of your garden.

Cousin Itt acacia

Acacia ?Cousin Itt? continues to be a favorite for many of us. This lovely small plant with emerald green, feathery foliage that stays small in the garden and has low water needs. Not to be confused with the bully acacia tree seen around here, it?s one of the good guys. Plant in full sun to partial shade.

So if you?re in the mood to add a couple of interesting plants to your garden, take a tip from what landscape designers use or grow in their own gardens.

Tranquil Blue in the Garden

With the heat of summertime upon us I?m drawn to those areas in my garden that have blue, white and lavender flowers. A hot day just seems cooler there.

Washed out magenta is nature?s favorite go-to color and the shade that hybrids will revert to it if allowed to go to seed. Among gardeners, red is a favorite color. Orange and yellow come next, then pink and purple with blue and white both comparatively rare in nature last on the list.

geranium ‘Orion’

So naturally, most of us gardeners want the elusive blue flower in our gardens. Knowing that cool colors recede, place them around the edges or at the back of a garden to make your space appear wider or deeper.

True blue flowers are rare. We use words like cerulean, azure, cobalt, sapphire, turquoise, electric blue or steel blue when describing blue flowers. Hybridizers have tried for years to produce a true blue rose or blue daylily. Blue plant pigment is hard to manipulate. It occurs in the daylily as a sap-soluble pigment and is difficult to segregate. Lilacs, purples, orchids and mauves we have and working with them hybridizers may eventually get near blue, but pure blue probably never. Recently, some companies have found a way to insert some blue in the center of their daylily flowers but a totally blue daylily has never been produced.

Rose hybridizers striving for true blue have come close by

hydrangea macrophylla

crossbreeding lavender hybrid teas in order to produce offspring having optimum amount of cyanidin, the pigment that imparts purple or magenta tones and flavone, the pigment that gives light yellow tones.The results have been more of a silvery lilac or mauve. A blue rose is still in the future although labs in Australia and Japan are genetically modifying the pigments from petunias to produce a blue rose. Their results are not yet perfected and these roses are more of a lilac in color and can not survive conditions outside the lab. It is apparently very difficult to isolate the pigment cyanadin. Delphiniums have a monopoly on it.

omphaloides

The color blue is calming and tranquil. It is the color of serenity and peace and is said to slow down the metabolism and reduce the appetite. When brightened with white or combined with yellow or orange in a complementary color scheme the results of blue in the garden are breathtaking. The great English gardener Gertrude Jekyll used plants with golden leaves or clear yellow flowers to spice up blue gardens. Just remember that blues and purples are the first flowers to fade as darkness falls so be sure to have those whites and yellows to carry your garden into evening.

There are many blue perennials as handsome as they are durable that we can enjoy in our gardens today.
Some of my favorites are old fashioned hydrangeas, violas and campanula. Both are valuable in the shade garden along with omphaloides and brunnera. The blue spikes of a long blooming peach-leaf campanula just go together with the white and green variegated foliage of Jack Frost Siberian bugloss.

agapanthus africanus

In early spring we are dazzled by our native ceanothus which bloom with deep blue, sky blue or electric blue flowers. Emerald Blue phlox subulata carpets the ground in spring with clear blue flowers that top creeping stems. Penstemon Blue Springs, a California native hybrid, carries dense spikes of bright blue, bell-shaped blossoms.

Make sure your garden has a blue section to cool you on a hot day.
