Bupleurum
|
Widely distributed around the temperate Northern Hemisphere and extending to the Canary Islands and South Africa, Bupleurum is a genus of the carrot (umbellifer) family which includes evergreen shrubs as well as annuals and perennials. It differs from most of its close relatives in having leaves that are simple and undivided. The shrubby species are many-stemmed from ground level and have somewhat leathery or succulent foliage. Flowers are small, mostly greenish or yellow, borne in neat compound umbels that may be grouped into larger panicles. The small dry fruits are similar to those of many other umbellifers such as parsnips and hemlock. |
CULTIVATION: The shrubby species come from warmer drier regions around the Mediterranean, and the Canary Islands. They grow best in a sunny exposed position in well-drained soil and are tolerant of salt-laden breezes near the seashore. Due to their manner of sprouting from the base they withstand hard pruning and may be trained into hedges. Propagate from cuttings, root divisions or seed. |

Washingtonia

This genus in the palm family Arecaceae consists of 2 species which come from southwest USA and northwest Mexico. These single-stemmed robust palms have fan leaves in which the leaf stalk extends into the blade as a midrib. The trunks are clothed in old leaf bases that hang like a skirt or petticoat; the decaying foliage can build up into a dense thatch over many years. The leaves are deeply lobed with fibrous margins, while the small, bisexual, tube-shaped flowers can be creamy white or creamy apricot-pink and occur in slender hanging clusters among the leaves. The small fruits are drupes, and each contains a single seed. They come from desert areas where they obtain moisture from springs or streams, and can be seen cultivated in drier parts of tropical and subtropical regions as well as in temperate areas. Both species are best grown in regions that do not experience year-round humidity, and Washingtonia filifera is the more cold tolerant. They are useful for lining roadways and for planting in parklands. |
CULTIVATION: These are very hardy and adaptable palms in a well-drained soil. They tolerate full sun, exposed conditions and, once established, drought. Decaying foliage can be a fire risk and is best removed. Propagate from seed. |
