Seed Packet Information: Hills of California
Hills of California
We hope you enjoy your seeds from the CNPS SCV Wildflower Ambassadors program. This plant mix is designed to provide flowers over a period of three months in the spring and early summer in a sunny area.
Planting Instructions
Fall through winter is the ideal time to start growing California native wildflowers as these have adapted to capitalize on the fall and winter rains (October-February is best) and bloom in spring. They may be planted through April, but after that it is best to wait until at least September to plant them as they do not do well when planted in late spring or summer.
Choose A Site & Prepare Your Soil
- Choose a spacious site in full sun.
- Prepare your soil (or several very large pots), by removing all existing growth and debris. If your soil is clay, break it up with some compost or cactus soil (sold at nurseries).
- Water thoroughly to help seeds settle into the soil. Continue to water a few times a week, unless it rains, so they don’t dry out after germinating. Seeds should sprout in one to three weeks.
- After you plant your seeds, let the area ‘go natural’ by leaving the leaf litter on the ground. While many butterflies go into chrysalis on stems or other hard surfaces like branches, many others go into chrysalis in the debris. If you rake or blow it, you could accidentally kill or throw them away.
Avoid using pesticides anywhere in your garden, it will kill the beneficial insects such as bees, butterflies, moths, and ladybugs that you are trying to attract. Try to ignore bugs, as they are part of the ecosystem (for instance, hummingbirds eat aphids). If you hose the plant or try to remove pests you may dislodge butterfly or ladybug eggs or kill tiny caterpillars. Avoid using herbicides as they also poison the ecosystem you are trying to nurture.

CNPS SCV Wildflower Ambassadors
CNPS SCV Wildflower Ambassadors (WFA) hand out free native seeds and information at events and library talks, join and assist with tours of local native gardens, enjoy seed packing parties together, pitch in at pollinator gardens and restoration projects and promote native gardening on social media. Above all, they have a good time while inspiring people to start their own native gardens and create habitat for our native bees, butterflies, birds and more.
The program is lead by Jennifer Dirking, the founder and inspiration for the Bring Back Bay Area Bees and Butterflies (BBBABB) group on Nextdoor. In the BBBABB Nextdoor group, members share ideas and upcoming events, invite friends to join, and post pictures of their gardens and of wildflowers they saw on hikes.

Wildflower Seed Planting
Grow Wildflowers - Grow Butterflies!
CNPS 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.
Each 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:
Click on the links above for detailed planting instructions and descriptions of the seed mixes. For more information, check out the instructions at the Larner Seeds website.
The 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!
