What's Blooming in the Nursery
Most of the time, these articles will be about specific plants that we think you would enjoy adding to your garden. But sometimes, we can't resist sharing the wonders that we see as we work in the nursery. This week the Grindelia camporum (Great Valley gumweed) was a pollinator magnet. Skippers, bees and flies (masquerading as bees) were busily feasting.
Of course, the parade of flowers didn't end there. A few of the others on display included:
- Achillea millefolium (common yarrow) - the Island Pink variety was eye-poppingly bright
- Corethrogyne filaginifolia (common sandaster)
- Dendromecon harfordii (bush poppy)
- Diplacus X (hybrid monkeyflower)
- Epilobium canum (California fuschia)- in addition to the usual reds, 'Summer Snow' brings white into the mix
- Ericameria nauseosa (rubber rabbitbrush)
- Eriogonum (buckwheat) - a huge selection of these wonderful summer and fall bloomers continue to put on a show.
- Monardella macrantha (hummingbird monardella)
- Monardella villosa (coyote mint)

Useful Vines for the Garden [August 8, 2015]

Two of the great vines available at the nursery are Vitis californica (California wild grape) and Clematis lasiantha (chaparral clematis). They are both useful habitat plants and can be grown as a ground cover or trained over a trellis or fence. They are tolerant of a wide variety of soils -- from clay to sandy soils.
Clematis lasianta (Chaparral clematis)
Clematis lasianta, which is also known as chaparral or pipestem clematis, is a lovely vine that is covered with gorgeous white flowers in the spring. The flowers are followed by fluffy white seed heads that make the plants look like they're covered in cottonballs. It can grow fifteen to twenty feet tall. This plant loves full sun although it prefers some shade for its roots. It does not need supplemental water after it is established. It is deciduous and may die back in cold winters, but will quickly grow back in the spring. You can see these vines in flower on many local trails in the spring.

Vitis californica (California wild grape)
![Vitis californica (California Wild Grape) Vitis californica (California Wild Grape)](/images/stories/nursery/DSC00549-vitis-californica-nursery.jpg)
Vitis californica has beautiful, large green leaves that provide an excellent cover in the summer. In the wild, it is typically found along streams and other moist areas, but is adaptable to dry conditions after it is established. It is a deciduous vine that can grow over thirty feet tall. Since it sheds its leaves in the winter, it's great over an arbor or trellis for summer shade and winter sun. It produces bunches of small purple grapes in the fall. The grapes are edible, but tend to be tart.
Maintenance is easy. Agi Kehoe, an active member of the Gardening With Natives subgroup shares these simple pruning instructions:
Winter pruning: thin out the vine by removing all but the major canes that form the structure. Once finished, there should be one mature cane per wire line on a fence, and maybe 3 canes on a 2' wide arbor. Cut the canes back to 2-3 buds, each cut should be 1/4" above the leaf node. This is also the time to secure the large canes to the trellis with ties.
Active growing season pruning: maintain the fast growth. If trained on a fence, prune to keep it close to the fence; if trained on an arbor, leave some fresh green canes hanging down from the arbor to create a softer look.

Milkweed (Asclepias) [August 31, 2015]

Milkweed (Asclepias) is the primary host plant for Monarch butterfly caterpillars. Planting locally native milkweed in your garden will provide much needed habitat for these beautiful insects. There are fifteen species of milkweed that are native to California. The Nursery currently grows two of them. More information about California milkweeds is available from the Xerces Society.
Keep in mind that a single plant is usually not enough to provide habitat for butterflies, and providing multiple species of milkweed is better than one. In her book, The California Wildlife Habitat Garden, Nancy Bauer recommends including at least three plants of each species grown.
Asclepias fascicularis (Narrow-leaved Milkweed)
As one might guess from its name, this milkweed has narrow leaves that grow up to five inches long. They are fairly tall plants, growing up to three feet tall with multiple stems topped with clusters of white and pink flowers from June through September.
This is the most adaptable of the California milkweeds, growing well in both sun and shade, and tolerating both clay and sand. They even do well under oaks and can be found under them in the wild. With their striking flowers and long blooming season, these are ideal plants for any garden.
They are perennials, but will die back to their roots in the fall. They reemerge from their deep taproot in the spring, putting out additional stems each year.
Although they are known for their relationship with the Monarch butterfly, their flowers are also popular with bees and other pollinators.
More information is available at Mother Nature's Backyard and Las Pilitas.
Asclepias speciosa (Showy Milkweed)
This milkweed is native to the Bay Area and northern California. It has wide fuzzy grey to white leaves and spectacular 4 to 5 inch pinkish-white flower heads. It can grow three or four feet tall, although it tends to grow slowly and may take a couple years to reach full height. It prefers full sun and does not need supplemental water once established.
Like narrow-leaved milkweed, it will die down to the roots in the fall. It usually emerges a bit later than narrow-leaved milkweed, so give it time to come up in late spring to early summer. The bloom period doesn't last as long - flowers tend to appear in June and July. However, the huge, gorgeous flowers more than make up for the shorter length of time.
More information about Showy Milkweed can be found on Calflora and Las Pilitas.
