2023-10-05T12:24:33-07:00Categories: Blog, California Native, Nora Harlow, perennials, subshrubs|Tags: , , , |

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

Lotus hirsutus

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

2023-07-05T23:59:01-07:00Categories: Blog, Nora Harlow, perennials, subshrubs|Tags: , , |

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

Scented Geraniums

2022-09-30T16:55:04-07:00Categories: Blog, Garden Plants, Nora Harlow, subshrubs|Tags: , |

Plants commonly known as scented geraniums are species and cultivars of the genus Pelargonium with especially fragrant leaves. Most pelargoniums have at least lightly aromatic leaves, but some are grown primarily for their fragrance. Minty, fruity, spicy, nutty, lemony, or other distinctive aromas are released when leaves are touched or bruised. Pelargonium 'Orsett', with mint-scented leaves, cascades over rocks and walls Scented geraniums are small, tender, fast-growing, semi-woody subshrubs native to summer-dry, winter-wet climates of southern Africa. They are easily grown where winters are mild and where, if summers are hot, some afternoon shade can be

Jerusalem Sage

2021-12-14T18:29:30-08:00Categories: Blog, Garden Plants, perennials, subshrubs|Tags: , , |

Although each species has a common name of its own, plants of the genus Phlomis are often called Jerusalem sage whether they hail from Portugal, Morocco, Turkey, or Israel. These are summer-flowering shrubs, subshrubs, or perennials with felted or woolly, sagelike leaves, many with serrated margins and silvery undersides. Whorled clusters of small, usually downward curving, two-lipped flowers are displayed at intervals along upright stems. Flowers are followed by ornamental seedheads that persist through the winter. Phlomis fruticosa (Jerusalem sage) In the garden Jerusalem sages blend well with many other low-water, sun-loving plants, especially the salvias and other

Evergreen Euphorbias

It may seem surprising that evergreen euphorbias aren't used more often in commercial and public landscapes, where year-round good looks and ease of maintenance are so highly valued. Euphorbia characias (Mediterranean spurge) All of these evergreen subshrubs have fairly predictable shapes and sizes, a neat, almost architectural habit, and extraordinary color combinations that both offset and complement many other plants. Although the floral show is a spring and summertime event, the sculptural quality of the leaves and stems makes evergreen euphorbias especially effective in the winter garden. Perhaps the failure to include the shrubby euphorbias in commercially maintained
