How to Create a Butterfly Garden

Butterflies are magical creatures. They captivate us with their beauty and freedom of flight. Often I’m asked when designing a garden to include plants that will attract them and design areas to provide habitat. Recently there was a hatch of orange Militta Crescent butterflies in our area. I’ve seen hundreds of them up here in Bonny Doon alone. What can I do to increase the chances of them sticking around ?

We have about 90 species of butterflies in the Monterey Bay area. Many of these occur only in our mountains, forests and chaparral environments. They are easy to attract and make a permanent feature of your landscape.

A butterfly garden should include plants that accommodate all stages of the life cycle – egg, larvae, pupa and adult. When both adult nectar and larval host plants are available, they will attract and support a butterfly population. In addition to the right plants, your garden should also have sun, a water source, protection from wind and clusters of plants. When maintaining your garden avoid the use of insecticides, including BT.

As adults, most butterflies feed on the nectar of flowers. Some local butterflies, however, like the Mourning Cloak and Red Admiral, feed primarily on rotting fruit or tree sap for moisture and nutrients and the California Sister also feeds on aphid honeydew.

In the larval stage, most butterfly species are limited to a single plant family and occasionally a single genus. To attract more Western Tiger Swallowtails, for instance, provide larval host plants such as willow, sycamore, alder, Big Leaf maple, sycamore, plum and ash. Common Buckeye lay their eggs on mimulus and verbena while California Sister prefer coast and canyon live oak. Planting a variety of grasses, perennials and shrubs like ceanothus, buckwheat, coffeeberry, bush lupine, manzanita. redwood violet, California aster and wallflower will attract many of the local butterfly species. If your garden is near a wild area that naturally supports the caterpillar stage, you can plant just the nectar plants to attract butterflies to your garden.

Filling your garden with nectar producing flowers is the fun part. Adult butterflies rely on sugar-rich nectar for their daily fuel. Different species have different flower color and shape preferences. Many butterflies produce scents that attract the opposite sex and many of these scents smell like the flowers that they are attracted to and visit. The scent of these butterfly pollinated flowers may have evolved as an adaptation to ensure their survival. Did you know that butterflies taste with their feet?

Butterflies typically favor flat, clustered flowers that provide a landing pad although larger butterflies can feed on penstemon and salvia while hovering. Butterflies have good vision but a weak sense of smell. Unlike bees, butterflies can see red and are attracted to brightly colored flowers. Pink, red, orange, yellow and purple are the most attractive nectar source colors but they also use blue and white.

Consider the blooming time of each plant. Having plants blooming in the sun for many hours in the day will lengthen your viewing time. Nectar rich flowers include yarrow, aster, verbena, scabiosa, buckwheat, toyon, salvia, erysimum, zinnia, lantana and coneflower.

In addition to nectar, butterflies need a source of water and salts. A patch of mud kept wet year round or a shallow depression lined with pebbles and kept moist will work fine. Also provide some flat rocks for them to bask in the sun in an area protected from the wind by shrubs.

Having your own butterfly garden will enable you to witness close-up the wonder of butterflies and the flowers on which they feed.

Watering Tips when Planting for the Birds & Bees

Western Tiger Swallowtail butterfly

I may not be so fond of gophers but I never tire of the birds, butterflies and bees that visit my garden. I’m always on the look out for plants that will attract even more of these exquisite creatures and it’s one of the top requests for nearly every garden that I design. Fortunately there are many plants that fit the bill and have low water requirements for our summer dry climate.

Trees that provide fruit, seeds, nectar and protein from insects attract many kinds of songbirds. Our native Big Leaf Maple is a favorite of the Evening Grosbeak who relish the seeds and early spring buds. Another bird magnet is the dogwood. Our Pacific dogwood as well as the Eastern dogwood and even the hybrid of the two, Eddie’s White Wonder, all are very valuable sources of food for many birds. Their summer berries are high in fat and important for migratory and wintering birds.

Lesser goldfinch

There are many great low water-use shrubs and perennials that attract birds. My favorite Lesser Goldfinch is partial to the seeds of yarrow, buckwheat and aster. Kevin’s mahonia is favored by Western bluebirds. Blooming now in our own neck of the woods is Mexican elderberry. Their butter yellow flowers will form purple berries rich in carbohydrates and protein and attract an incredible number of birds. And I always can find space for another variety of manzanita or ceanothus.

Mimulus ‘Jelly Bean Gold’

Both hummingbirds and butterflies are attracted to flowers that provide nectar. Among their favorites that won’t break your water budget are natives such as penstemon and salvia. galvezia, mimulus, monardella. California fuchsia and ribes are also important nectar sources for birds in your garden. Add a couple non-native, drought tolerant perennials like lavender, gaura, coreopsis, verbena, scabiosa, lantana and wallflower and you’ll provide a feast for all your winged visitors.

So how much water do different types of plants need during the heat of summer?

As a rule of thumb, trees and large shrubs need deep but infrequent waterings. They should be on a separate valve than your smaller shrubs and perennials. Water ornamental trees 1-3 times per month depending on the type and soil. Tree roots grow 12-36” deep and require 10 gallons of water per inch of trunk diameter.

Sambucus nigra berries

Apply with a soaker hose, drip system emitters or hand held hose with shut off and soft spray attachment according to your water districts restrictions. Don’t dig holes in the ground in an effort to water deeply. This dries out roots even more. Be sure to water the root zone to the indicated root depth every time you water. Watering deeper than the root zone only means you are wasting water. You can test how deep you watered by pushing a smooth rod -1/4” – 3/8” in diameter- into the ground soon after you irrigate. The soil probe should easily slide through the wet soil but become difficult to push when reaching dry soil.

The roots of smaller shrubs are 12-24” deep in the soil. Established native shrubs may need only monthly irrigation to keep them looking their best while other shrubs may need watering every 7-10 days during the heat of the summer. Perennial roots only go down 12” or so and may need watering once or twice a week depending on type.

With lots of mulch and the above watering tips you can keep all your plants happy and healthy for the birds, butterflies and bees to enjoy.

Drought Tolerant Plants for Birds & Butterflies

red_breasted_nuthatchI admit I’m spending way too much time watching new birds come to the feeder. Every time I pass a window I check to see if the pair of purple finches is gobbling up the sunflower chips. She seems to love the safflower seeds, too. The pygmy nuthatches are the bullies of the feeder. Guess no one has told them they are teeny tiny little things. Spotted towhees come when the juncos are done and the stellar’s jays are gone. The Anna’s hummingbirds were really prolific this spring. Their young are drinking nectar almost faster than I can refill the feeders. I have lots of mimulus, salvia and ceanothus flowers for them to enjoy but I need more plants that attract hummingbirds and butterflies.  I want to conserve water and also enjoy my winged friends.

Unthirsty plant choices are high on my list this year. Some of my favorite plants are survivors- easy to grow with minimal water use once established while also attracting hummingbirds and butterflies to the garden.

Everyone should have some lavender in their garden. Hummingbirds and butterflies both favor this plantlavender_West_Zayante and there are new introductions every year from growers. There are dozens of new varieties to choose from. Hidcote Superior forms a bushy compact mound with sensational purple flowers in early summer. Or you might try Royal Purple, Betty’s Blue, Violet Intrigue, Sachet or Royal Velvet. Goodwin Creek is an old stand-by that blooms from spring to late fall with deep violet blue flowers. For midsummer bloom plant Grosso which is a widely planted commercial variety in France and Italy. It’s possibly the most fragrant lavender of all. Spanish lavender blooms spring into summer if sheared. By planting an assortment of lavenders you can have a succession of flowers throughout the season.

Penstemon also lure hummingbirds and butterflies to the garden. They come in a wide range of colors and varieties from native species to garden hybrids. I especially like the red flowers of Garnet and the blossoms of the natiOLYMPUS DIGITAL CAMERAve Blue Bedder.

Another long blooming, tough plant is achillea Moonshine. Butterflies love to alight on their yellow flat landing pads of this yarrow.  The dense flower clusters make good cut flowers and the gray-green foliage blends with all color in the garden. Yarrow need only routine care once established. They can take some watering although they endure drought once established. Cut them back after bloom and divide when clumps get crowded.

There are so many salvias to choose from and all are great additions to a tough love garden. Autumn sage blooms summer through fall in colors ranging from deep purple through true red to rose, pink and white. Purple Pastel is especially beautiful covering 3-4 foot plants with blossoms filled with nectar for hummingbirds and butterflies.

Those who seek true blue flowers for their gardens might try planting salvia chamaedryoides. This elegant front-of-the-border plant has silvery foliage which sets off the brilliant blue flowers. Heaviest bloom is in late spring and fall. Deadheading encourages re-bloom.  This salvia is drought tolerant but blooms longer and better with a little occasional summer water.

More un-thirsty bloomers that attract either hummingbirds, butterflies or both and are easy to OLYMPUS DIGITAL CAMERAgrow are gaura, coreopsis and homestead purple verbena. Asters, Russian sage, black-eyed Susan, bee balm, mums, autumn joy sedum and cosmos are also on the menu of our winged friends.  Many of these also make good cut flowers.

Plant some new water efficient plants for color that attract hummingbirds and butterflies. Afterwards spread  fresh bark or compost to mulch the soil. This insulates and protects shallow roots from the heat of the summer sun. While keeping the soil cool, mulch slows the evaporations of water from the soil so it stays moist.
