Wildflower Seed Planting
Grow Wildflowers - Grow Butterflies!
CNPS Santa Clara Valley Chapter is promoting biodiversiity by giving free wildflower seeds to enthusiastic gardeners who can re-energize the ecosystem in their home gardens. Together, we can bring back butterflies, bees, and birds. 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.
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.
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 the plants in this packet 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.

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:

Seed Packet Descriptions and Planting Instructions
These plants are designed to provide a bloom over a period of 3 months. The moths and butterflies hosted by these plants is just a sample, these plants are a host to many more.
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).
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.
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 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.

*”Host” = key food source for the caterpillars of these particular butterflies, that co-evolved to specialize over thousands of years. Butterflies die out without these plants.
The moths and butterflies hosted by these plants is just a sample, these plants are a host to many more.
Planting Instructions
Fall is the ideal time to start growing California native wildflowers, so they can become established and bloom sooner. But you can also sow them in winter or as late as early spring. This packet covers 80 sq. ft.
Choose A Site & Prepare Your Soil. Choose a site with a minimum of 6 hours of sun or dappled shade. Prepare your soil by removing all existing growth and debris.
If your soil is clay, break it up with some compost or cactus soil (sold at nurseries). You could opt to cover the area 4” thick with cactus mix to smother potential weed seeds.
Don’t fertilize the area, as this will not mimic the native soil these plants are used to and could impede their growth
Scatter seeds very thinly and rake them gently into the soil. Don’t cover them with any more soil or they may not germinate.
Water thoroughly to help seeds settle into the soil. Continue to water a few times a week so they don’t dry out after germinating. Or simply wait for the rainy season and water on the dry days.
Try to let the area ‘go natural’ by leaving the leaf litter on the ground. Many butterflies go into chrysalis in the debris and if you rake or blow it, you could accidentally throw them away.

Native Plantings in Jeffrey Fontana Park
A beautiful selection of mature and new native plant gardens can be found in Jeffry Fontana Park in San Jose. Wandering through the park, you will find plants from both northern and southern California in a variety of settings.
This is the perfect place to view plants that grow well in San Jose and find ideas for your own gardens.
From buckwheats to monkeyflowers to California fuschias, you’ll see something in bloom year-round. Many of the plants are labelled, making it easy to identify your favorites.
The two original berms were planted in 2011 as an alternative landscape feature to tall trees under PG&E power transmission lines. The plants are well-established and no longer need irrigation.
Five Islands
This garden was planted at the beginning of 2018, although the concept was conceived years before. In the words of Patrick Pizzo, its founder:
The concept of the Five Island Project was born about six years ago. We wanted to create islands or berms much like the two that we first introduced into our park, Jeffrey Fontana, as an alternative landscape feature to tall trees, which have impact on the safe delivery of power transmission by PG&E. You see, our two parks, T.J. Martin and J. Fontana are contiguous along the PG&E power transmission easement in south San Jose. Our contribution, toward potential loss of trees, was to develop native plant and shrub alternatives. This was our first effort.

Now near this island is an open area between heritage coast live oak trees, Quercus agrifolia. Our vision was to have a network of islands/berms in this open area. Neighbors wanted to have an alternative to weeds and summer dust storms. The area is about 120 foot by 120 foot. We envisioned five CA native plant islands in this open area.
Part of the reason for the passage of time was due to the drought. The City policy became ‘no new plantings’. Then, a couple of years ago, with MFPA postured financially to support a major project, the idea came to the fore and I was asked to implement the proposed project. During the four years leading up to this okay, we had been in multiple conversations with our Parks Department in San Jose about the Five Island Project. About a year ago, we broke ground.
The elongated islands are about 35 by 15 foot and of elliptical shape. The spine is about 2 foot high, tapered to ground level, providing good drainage. The native soil was removed or ‘dished’; and this native dirt (sand and adobe) was mixed with ‘garden soil’ from Evergreen Supply in San Jose. It is the lowest grade of organic soil on the market. The combined soils were used to create the islands/berms. Each island is sponsored, to raise money to implement the project. We have five sponsors: East Bay Wilds, DGDG, Almaden Valley Nursery, PG&E and the past presidents of our organization: MFPA (Martin-Fontana Parks Association):
https://martinfontanaparksassociation.blog

After forming the islands, plants were planted. Each sponsor selected plants and designed their own gardens. Directly after planting, drip-irrigation was installed. We are using Techline drip line with pressure-opened emitters: 1 gallon per hour per emitter. The emitters are spaced 18 inches apart. I designed the irrigation system and will relate at the site-visit. Currently, due to low rain (nothing Jan and Feb), we irrigate every 8 days for 1/2 hour and this is working out fine. We have a variety of water-need plants on the island, by design, so it will be a challenge to fine-tune any summer watering. The islands were planted from mid-Jan through the end of February, which worked out great as you recall the beautiful weather (minus rain). The plants seem very happy with their new homes.
