The Micheal A. Hall Park Pollinator Garden and Rain Garden was installed in early 2024 by the Town of Windsor as part of a larger detention basin project taking place in the park. The pollinator garden was designed by Landscape Architect, April Owens, with the intention of using California native plants to create a thriving habitat for our local pollinators. The Town of Windsor is committed to creating drought tolerant living landscapes that promote both water conservation and biodiversity in our environment. We hope this garden inspires residents to apply similar functional and beautiful designs in their own home yards and gardens.

The Michael A. Hall Park Pollinator Garden features 100% California Native Plants. Key plants include Narrow Leaf and Showy Milkweed to support the Monarchs, California Fuchsia which attracts hummingbirds, and Groundcover Buckwheat which the Bees can’t get enough of. The garden is irrigated by a drip irrigation system, resulting in maximized water efficiency.

Just beside the pollinator garden is a beautiful and functional rain garden. The rain garden was installed as an offset to another town construction project and has resulted in a wonderful addition to the park. Using intentional topography, bio-engineered soils, and specially selected plants, the rain garden works to filter pollutants form the street out of storm water runoff and slowly infiltrate the water back into the ground.

In just one year, both of these gardens have grown into important habitat for birds, bees, and butterflies, and have served as important educational opportunities for the entire community.

On the day of the garden tour, the California Native Plant Society, the Town of Windsor and other will be present to display this new garden and help answer your own gardening questions.

Plants in this Garden

Plant Picker

Sambucus spp

Elderberry
Organization

Fast-growing shrubs and small trees for sun or part shade that attract pollinators from far and wide to large clusters of cream flowers in spring, followed by berries in summer that provide food to many types of birds. Fruit can also be used for culinary purposes. While naturally fairly wild-looking, elderberries can handle being cut back to the ground in the winter or pruned to maintain size and shape.

Examples:

  • Blue elderberry (S. mexicana [nigra] spp. caerulea, 8-25’) is native from Oregon to Baja California and beyond.
  • Black elderberry (S. nigra, 20-30’) is native to Europe, North Africa, and Asia, and is available in nurseries in the form of many named cultivars. Cut leaf black elderberry (S. n. ‘Black Lace’, 8’ x 8’) has intense dark, fine foliage. Cut leaf elderberry (S. n. ‘Laciniata’, 10’ x 10’) has green leaves, and variegated black elderberry (S. n. ‘Marginata’, 6-12’) has variegated leaves.

Zauschneria [Epilobium] spp

California Fuchsia
Organization

Group of highly variable, semi-evergreen subshrubs and herbaceous perennials distributed over a wide geographic area, including California. Epilobiums bloom in late summer with tubular flowers providing a food source for hummingbirds migrating south and are also attractive to bees and butterflies. Epilobiums range from low-growing groundcovers to upright plants of several feet. Flower colors include orange-red, white, pink, and salmon. Most can be pruned back in late autumn to maintain a more compact form and be rejuvenated for the following year.

Low-growing examples: E. ‘Schieffelin’s Choice’; E. canum ‘Calistoga’, a selection from Phil Van Soelen from California Flora Nursery from the Palisades east of Calistoga; E. canum ‘Cloverdale’, a selection from U.C. Santa Cruz Arboretum from along the Russian River north of Cloverdale with exceptionally orange flowers; E. c. ‘Everett’s Choice’, E. c. ‘Summer Snow’ with white flowers, and E. septentrionale ‘Select Mattole’, a somewhat redder flowering selection that is more shade-tolerant.

Upright examples: E. c. ‘Bowman’s Hybrid’ (2-3’), E. c. ‘Catalina’ (3-4’), E. c. ‘Liz’s Choice’ (3’) selected by Milo Baker Chapter CNPS Fellow Liz Parsons, E. c. ‘Marin Pink’ (2’) with pink flowers.

Heteromeles arbutifolia

Toyon
Organization

California native, evergreen shrub or small tree often seen growing in Sonoma and Marin county wildlands. Lacy, white flower clusters in spring attract pollinators; red berries in winter provide a splash of color and an important food source for birds. The name “Hollywood” was born from the abundance of toyon in the hills of southern California and its resemblance to European holly. The cultivar ‘Davis Gold’ has yellow berries and may be more disease-resistant than the species.

Manzanita bush

Arctostaphylos spp & cvs

Manzanita, 'Dr. Hurd'
Organization

Manzanitas vary from carpet-forming groundcovers to small trees. Manzanitas have varying shades of striking, reddish brown bark and can provide structure to a garden. These plants have evergreen foliage, small white-to-pink, urn-shaped blossoms in late winter to early spring, and then small fruits that resemble tiny apples.

Groundcovers: A. ‘Emerald Carpet’ (1’ x 3-6’), A. ‘Pacific Mist’ (2-3’ x 6-8’), A. nummularia ‘Bear Belly’ (1’ x 3’), A. uva ursi ‘Radiant’ (6” x 4-6’), A. uva ursi ‘Wood’s Compct’ (1’ x 3’).

Shrubs: A. ‘Howard McMinn’ (5-7’ x 6-10’), A. ‘John Dourly’ (3-4’ x 5-6’), A. ‘Lester Rowntree’ (8-10’ x 10-15’), A. ‘Sunset‘ (5-7’), A. bakeri ‘Louis Edmunds’ (8-10’), A. manzanita ‘Sentinel’ (6-8’ x 5’), A. hookeri ‘Wayside’ (3′ x 8′).

Trees: A. manzanita ‘Dr. Hurd’ (10-15′)

Penstemon heterophyllus

Blue Foothill Penstemon, California Penstemon
Organization

Penstemons are a large group of woody or herbaceous perennials with narrow leaves and tubular flowers. Foothill penstemon is a widely known and grown California native with iridescent purple-blue flowers during spring and early summer that are attractive to hummingbirds. The cultivar known as ‘Margarita BOP’ is widely available, reliable, and garden- tolerant. Remove spent flower spikes to encourage more flowers.

Salvia spp

Sage
Organization

Salvias are a huge group of more than 900 species that include annuals, perennials, and shrubs adapted to a variety of climates and have varying water requirements. Salvias are attractive to hummingbirds, butterflies, and bees, and are generally ignored by deer. Sages that are native to California are generally drought-tolerant, prefer full sun, and little to no fertilizer. Annual pruning in late summer or fall generally helps to keep plants tidy and healthy.

CA native sages:

  • S. apiana, white sage (3-4’ x 4-6’), silvery-white, aromatic leaves with tall flower spikes of white flowers, popular for honey production and in bundles as a natural incense.
  • ‘Bee’s Bliss’ (1-2’ x 6-8’), superb, light gray groundcover with light purple flowers on long spikes; damp conditions can cause mildew which will clear with warm weather and sunny conditions.
  • S. clevelandii, Cleveland sage (3-5’ x 3-5’), medium-sized shrub for hot, dry locations known for pleasant fragrance and deep blue whorls of flowers; popular cultivars include S. c. ‘Allen Chickering’, S. c. ‘Pozo Blue’, and S. c. ‘Winnifred Gilman’.
  • S. leucophylla, purple sage, includes plants with both an upright growth habit, such as S. l. ‘Amethyst Bluff’ (3-5’ x 3-5’) and others with a sprawling form, such as S. l. ‘Point Sal’ (2-3’ x 6’), both of which are from Santa Barbara county.
  • S. sonomaensis, Sonoma sage (1-2’ x 3-4’), groundcover that prefers light shade and will not tolerate damp conditions; cultivars include S. s. ‘Dara’s Choice’, S. s. ‘Greenberg Gray’, and S. s. ‘Hobbit Toes’.
  • S. spathacaea, hummingbird sage (1-2’ spreading), herbaceous groundcover that grows well in dry shade and spreads slowly by underground rhizomes; large leaves have a wonderful fruity fragrance; the only red-flowered native sage.
  • S. mellifera, black sage (6′ x 10′), evergreen shrub that grows well in full sun and well drained soils. Dark green leaves with pale purple flowers in late spring and early summer.

Non-native sages:

  • S. chamaedryoides, germander sage (2-3’)
  • S. chiapensis, Chiapas sage (1-2’ x 3-4’)
  • S. greggii, autumn sage (1-4’ x 1-4’)
  • S. leucantha, Mexican bush sage (3-4’ x 3-6’)
  • S. microphylla, cherry sage (3-4’ x 3-6’)

Gardening Tips

Plant a Foundation of Shrubs

In a native garden, it is important to plant a foundation of shrubs like those on our favorites list so that in any season the garden looks beautiful, even when some of the plants may be deciduous. Using California native plants provides so much habitat, and it’s important to let them go to seed and be a little messy by typical standards. The delight of providing food for butterflies, bees, and birds is well worth it. We can all save biodiversity one garden at a time.
