Wildflower Seed Planting

Grow Wildflowers - Grow Butterflies!

Acmon Blue ButterflyCNPS Santa Clara Valley Chapter is promoting biodiversiity by giving free wildflower seeds to new native plant gardeners in our chapter area (Santa Clara and San Mateo counties) to re-energize the ecosystem in their home gardens. Together, we can bring back butterflies, bees, and birds. Find us at events to receive free seeds.

poppies & goldfieldsEach seed packet you receive from us contains California native wildflowers in rich hues of gold, orange, pink, purple and blue that, depending on their mix, will cover an 80-130 square foot area if scattered thinly and allowed space to grow to their natural dimensions.  The flowers will bloom in succession from early spring through late summer. You can disperse these seeds in an area planted with native grasses for a meadow effect. 

Scattering a packet of native wildflower seeds is a joyful way to restore lost essential habitat while enhancing your gardening experience. We hope you revel in the beauty of the flowers, colorful caterpillars, variety of pollinators, baby birds, and the dance of life in your garden. We offer several varieties of seed packets containing mixes from Larner Seeds:

clarkias-crop2-small.jpgThe beauty, color, and scent of flowers fill us with joy. Yet, very importantly, to the bees, butterflies and birds, flowers are an essential source of nourishment for their survival. The plants and flowers provide pollen for bees, nectar for butterflies and moths, and essential food for their young, the caterpillars. Butterflies drink nectar from many different types of flowers, but lay their eggs on just one or two types of host plants that will feed their offspring. The Variable Checkerspot, Silvery Blue, and other butterflies and moths rely on plants in these seed mixes as a caterpillar food source. The caterpillars, in turn, are essential for the survival of our local birds, since 96% of the birds that visit your yard depend on caterpillars to feed their young. Read New York Times Best Seller Nature’s Best Hope by Doug Tallamy or tune into the video. Spread the word to your friends and neighbors. Some neighborhoods are creating “butterfly corridors” with patches of wildflowers and native plants in each of their gardens. Enjoy!
