The first rains are falling, and that means it's time to plant native bulbs. Native plants perform the best when planted out before the rainy season moves into full swing. This allows them to establish a strong, healthy root system before the summer drought returns.
Before you rush to your local nursery to select your new treasures, survey your garden environment. Native bulbs are not difficult, but unlike cultivated "garden variety" bulbs, which are bred to enjoy a range of typical garden environments, native bulbs do have strict habitat preferences.
Here in the Bay Area, once-common native bulbs and bulb-like plants (those with rhizomes, tubers, or corms) include: mariposa lilies (Calochortus species), Blue-Eyed Grass (Sisyrinchium bellum), Wild Onions (Allium species), Fritillaries, Camas Lilies(Camassia species), and native Tiger and Turk's Cap lilies (Lilium species).

Pay attention to your bulbs' cultural needs before you plant them. Certain plant associations may sound beautiful in theory, but cannot be achieved. For example: Some bulbs, such as the mariposa lilies, require a period of dry summer dormancy, and should not be watered during the summer drought period. Other bulbs are indigenous to wet, riparian areas and require supplemental watering. Mariposa lilies must rest during the summer drought, and should not be planted with Turk's Cap or Tiger lilies, which are native to moist, woodlands and enjoy a year-around watering regime.
If you have a Mediterranean garden, consider planting Brodiaeas, Triteleias, and Dichlostemmas in your borders. Plant them with Mediterranean plants, such as lavender and sage, or mix them into a native meadow. Also try them with conventional bulbs that do not mind a dry summer climate, such as miniature narcissus, or species tulips. Keep in mind that most California native bulbs are smaller in scale, and more delicate, than garden-variety tulips. They work well in rock gardens and perennial borders.
- Brodiaeas, also known as "Harvest Lilies," bloom in springtime. Low-growing, with grassy leaves, they resemble daylilies but exhibit a more delicate form. Brodiaea blossoms are typically pink or lavender. Most species enjoy a sunny site and can take clay soils. The owners of Far West Bulb Farm, a specialty grower of native bulbs in Colfax, California, note that plants from the Brodaiea and Triteleia groups "actually grow more robustly if they receive occasional watering during the dry season."

- Triteleias have small, star-like flowers. They typically grow in grassy, open meadows, but can also be found in open woodlands and on rocky cliffs. In the Sierra foothills, Foothill Pretty Face (Tritelaia ixiodes) adds a charming butter-yellow accent to the area's beautiful spring wildflower show.

- Dichlostemmas are commonly known as "Wild Hyacinths." They produce clusters of delicate flowers in spring, in umbels or racemes. Dichlostemma capitatum (Blue Dicks) were an important food source for Native Californians. They can take some sun and heat, and perform well in a range of soils and climates.
Buy your bulbs from a reputable nursery or garden center. It is illegal to gather bulbs from the wild. You may gather seedheads from wild plants, so if you are exceptionally patient or enjoy experiments, you could try starting your own bulbs from seed. If you gather from your local area, you will be propagating -- and planting -- the subspecies or variety native to your local ecosystem.
Nurseries sometimes carry hybrids of Triteleia and Brodiaea. Brent and Becky's Bulbs is a reliable, mail-order source for these unusual bulbs. Mail order catalogues, like Brent and Becky's, carry cultivars like Triteleia ixiodes 'Starlight,' a selected form that exhibits brighter flowers, and a taller form than its wild cousins, as well as wild varieties of Triteleia.

I have a number of wild hyacinth growing on my property. We are going to be building a deck on the back of our house where a number of them come up each year. Can I transplant them to another area? Obviously it would be easier to move them in the spring when I can see them. Is this possible or do I need to stake them for identification later in the year like summer or fall? Any info would be appreciated.

Wild hyacinths are pretty hardy. You can transplant them to another area. While it is possible to transplant bulbs while in bloom, the easiest time to dig and move bulbs is either in the fall, when they are dormant, or just after their bloom season.
Wait until the flowers are finished, and the foliage begins to yellow and die, and dig your hyacinth bulbs. The plants need their leaves to manufacture food for the next season, so don't cut/mow/move until the plant returns to dormancy. If you move your wild hyacinths while the leaves are still on, but yellow (when they first begin entering their summer dormancy), you should be fine.

In most cases I do not make comments on blogs, but I want to say that this post really forced me to do so. Really nice post!
