Leucadendrons for the Garden

2022-01-22T05:13:41-08:00Categories: Blog, Nora Harlow, shrubs|Tags: , , |

Familiar to many as a knockout component of floral arrangements, leucadendrons are every bit as impressive in the garden. Most are best grown where winters are mild, soils are acidic, and excellent to perfect drainage can be provided, but some are less fussy than others. Dozens of these South African endemics are native to varied habitats, from damp coastal flats to frosty mountain slopes and from the summer-dry Western Cape to summer-rainfall KwaZulu-Natal. Leucadendron 'Little Bit', a hybrid of L. salignum and L. discolor, is a delicate offset here to the bold blue leaves of Agave americana  Most leucadendrons

Aloe arborescens

2022-01-05T08:23:53-08:00Categories: Blog, Garden Plants, Nora Harlow, shrubs, succulents|Tags: , , |

There is nothing timid about Aloe arborescens. At six to eight feet tall and at least that wide, with multiple, densely packed rosettes of thick, succulent, bluish gray-green leaves, this adaptable, shrubby aloe takes the stage wherever it is planted. Native to summer-rainfall southeastern Africa, the torch aloe, as it is often called, also thrives in mild-winter, summer-dry climates. Aloe arborescens Not content to dominate by size alone, in winter this aloe sends forth upright spikes of intensely red or red-orange, tubular flowers that rise two feet above the leaves. A mature plant with dozens of flowering spikes

Jerusalem Sage

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

Sasanqua Camellias

There was a time, not that long ago, when sasanqua camellias were less well known to most gardeners and less often grown in gardens than japonicas, but that time has surely passed. Of the dozens of sasanquas available from specialty nurseries and online, a few can even be found in the gardening sections of big-box stores. 'Yuletide' on a frosty winter morning There are many reasons for the popularity of Camellia sasanqua and its abundant offspring, especially in summer-dry climates. Most camellias do best in mild, humid climates with regular summer water, but established sasanquas, with afternoon shade

Parrotia persica

2021-10-09T09:16:47-07:00Categories: Blog, Garden Plants, shrubs, trees|Tags: , , , |

A connoisseur's tree, Parrotia persica or Persian parrotia offers a virtual kaleidoscope of colors and textures from one season to another and over the years. Through the seasons the deeply veined, serrated, broadly oval leaves of this deciduous, multitrunk or low-branching tree turn from spring's bronzy purple to summer's rich green to a sometimes astonishing fall combination of reds, oranges, yellows, and even pinks. Individual trees can vary widely in their fall display, and not every year brings the exact same colors at the same times on the same tree. Parrotia persica leaves in fall color Adding to

Wild Buckwheats

What could be more emblematic of the summer-dry/winter wet, semi-arid, and arid climates of western North America than the wild buckwheats? Annuals, perennials, and low to medium or tall shrubs, one or more species of Eriogonum is native from western Canada to Baja California and throughout much of the intermountain west. More than 100 species are native to California, from seaside cliffs to rocky alpine outcrops. Eriogonum grande var. rubescens Most of the buckwheats commonly available to gardeners are shrubs or shrubby perennials with green to gray-green or silvery gray leaves and masses of tiny flowers in small,

Eucalyptus macrocarpa (mottlecah)

2021-05-13T17:27:49-07:00Categories: Blog, shrubs|Tags: , , |

With its large, tightly packed, silvery bluish white, mint-scented leaves and outsized, scarlet, pink, or rarely yellow flowers, this shrubby eucalyptus brings show-stopping drama to almost any summer-dry garden. Its features are decisively eucalypt, but its effect, especially at full height and in full bloom, is Alice-in-Wonderland. Eucalyptus macrocarpa can be pruned to maintain it at almost any size. Here it combines perfectly with Agave americana.   One of several Australian shrubs called desert mallee, mottlecah can reach eight to ten feet tall and wide, sometimes erratically upright but more often sprawling. Mallees are shrubby eucalypts native primarily
