Erigeron glaucus, the aptly named seaside daisy, is an herbaceous perennial or subshrub with composite flowerheads that blanket the plant from spring into fall. Native to coastal bluffs and dunes from northern Oregon south to Santa Barbara County, California, its flowers are wildly popular with bees, butterflies, and other pollinators. Erigeron glaucus (seaside daisy) The species is somewhat variable. Habit ranges from a nearly flat mat to a mound more than two feet tall. The semi-succulent leaves can be grayish green, dark green, or bright green and broadly lance-shaped to oval, spoon-shaped, or spatulate, often with wavy
Most longtime gardeners know this low, velvety, gray-leaved subshrub as Dorycnium hirsutum, by which name it is still often referenced today. Described by Linnaeus as Lotus hirsutus, it was recently returned to that genus, but the name change has been slow to receive wide acceptance. Lotus hirsutus (Dorycnium hirsutum) with Aloe striata in Ruth Bancroft Garden Assuming that the plants I’ve seen and grown over the years are all the same species, Lotus hirsutus seems to be quite variable. The plants in my garden today are mostly upright and mounding, two feet tall and three to four
Cedros Island verbena puts on quite a show. Tiny, five-petaled, star-shaped flowers with a faintly sweet-spicy fragrance are tightly packed into round-topped, inch-wide clusters. Clusters are continuously refreshed as older flowers discreetly disappear and new buds open at the tips of short spikes. The small, deeply divided, bright green leaves on wispy-looking but sturdy stems lend a delicate, almost lacy effect. Glandularia lilacina 'De La Mina' flowering with muhlenbergia and ceanothus Cedros Island verbena (Glandularia lilacina) was formerly known as Verbena lilacina and is still popularly known by and marketed under that name. The plant is native
It is perhaps not surprising that bulbines and bulbinellas are often mistaken for one another. Both form clumps or rosettes of grasslike or straplike basal leaves and both bear tiny, star-shaped, yellow, orange, or white flowers in cylindrical or cone-shaped clusters atop tall stems. Most of both genera are native to South Africa with a few bulbines from Australia and a few bulbinellas from New Zealand. Bulbine latifolia has succulent leaves resembling an aloe without spines There are, however, significant differences between the two that may affect how they are used in the garden. Almost all bulbines
It might seem that hellebores are for expert gardeners and collectors only and a few of them are. The rest may look delicate, fussy, and difficult to grow but are quite amenable to cultivation in a fairly wide range of soils and situations. Hellebores, especially species but also many of the hundreds of cultivars, lend a connoisseur’s cachet to gardens in summer-dry parts of the world. Helleborus orientalis, beautiful in its own right, is the main parent of many hybrids If you are a newcomer to hellebores, there are several things it might be helpful to know.
You will hear that Matilija poppy (Romneya coulteri) is hard to start and hard to stop, and to some extent this is true. But if you plant this magnificent California native from one-gallon cans in late fall or early winter, and the spot you choose has excellent drainage (hillsides, mounds, raised beds), you should have self-sustaining plants by the second year. Plant carefully without disturbing the roots. Water thoroughly at planting and weekly through the first summer. The huge (4-6 inches across) white, crepe-papery flowers with bright yellow stamens each last about a week and then cleanly drop all their
If you're looking for a perennial that feeds many butterflies, birds, and bees and serves as a host plant for many caterpillars, you can't do much better than a native solidago. With one or more species native to every state in the United States and much of Canada, the genus is high on the list of "keystone" plants for every ecoregion in North America. Painted lady (Vanessa cardui) butterflies on solidago With the common name of goldenrod, solidagos could be confused with half a dozen other plants that share the name but do not have the same stellar
