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.
For more information and questions email us at This email address is being protected from spambots. You need JavaScript enabled to view it.. We can only accomodate seed requests for our chapter area. If you are not in Santa Clara County or southern San Mateo County, please contact your local CNPS chapter. Want to join? Apply here: https://forms.gle/nWTo5MN19VqPzg9s7

Wildflower Seed Planting
Grow Wildflowers!
CNPS Santa Clara Valley Chapter is promoting biodiversiity by giving free wildflower seeds to 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 our Wildflower Ambassadors 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 will cover three to four square feet or several large pots. You can scatter 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.
Planting Instructions
- Choose a site in full sun to partial shade.
- Prepare your soil by removing all existing growth and debris. If your soil is clay, break it up with some compost or cactus mix (sold at nurseries).
- Scatter your seeds over the prepared area. For more even coverage, you can mix your seeds with a little sand before scattering them.
- 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 your plants are several inches tall, 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.
The beauty, color, and scent of flowers bring us joy. However, it's crucial to remember that for bees, butterflies, and birds, flowers serve as a vital source of nourishment for their survival. Plants and flowers provide bees with pollen, butterflies and moths with nectar, and caterpillars with essential food in the form of leaves. Butterflies, for instance, sip nectar from various flowers but lay their eggs exclusively on certain host plants that will nourish their offspring. The Variable Checkerspot, Silvery Blue, and other butterflies and moths depend on these plants as a food source for their caterpillars. In turn, these caterpillars play a crucial role in the survival of local birds, as 96% of the birds that visit your yard rely on caterpillars to feed their young. To learn more about this fascinating relationship, consider reading Nature's Best Hope by Doug Tallamy or watching this video. Share this information with your friends and neighbors. Some neighborhoods are even creating "butterfly corridors" by planting patches of wildflowers and native plants in their gardens. So, take a moment to appreciate the beauty and importance of flowers in our ecosystem.
