GENUS INDEX

GENUS CODE: KALMI
GENUS SCIENTIFIC: Kalmia
GENUS AUTHORITY: L.
GENUS COMMON: Laurel
GENUS SUMMARY: A genus of 9-11 species, shrubs, of North America and Cuba, except the circumboreal K. procumbens (formerly Loiseleuria). Leiophyllum, traditionally treated as a monotypic or small genus of se. United States, is better treated as a part of Kalmia along with the northern Loiseleuria, based on molecular and morphological studies (Kron & King 1996, Kron et al. 2002). While this idea may initially seem outlandish (particularly to those whose concept of Kalmia is based only on Kalmia latifolia), the morphological and habital similarities of Leiophyllum to Kalmia are striking. The foliage and wood of all species (and the smoke from burning them) are poisonous.

FAMILY INDEX

FAMILY CODE: ERICAC
FAMILY SCIENTIFIC: Ericaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Heath Family
FAMILY SUMMARY: A family of about 107-124 genera and 3400-4100 species, primarily shrubs, small trees, and subshrubs, nearly cosmopolitan. The Ericaceae is very important in our area, which is one of the north temperate centers of diversity for the Ericaceae, with a great diversity of genera and species, many of them rather narrowly endemic. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.

HORTICULTURAL
Plant Sale Text: Mountain-laurel is among our showiest native shrubs and makes a wonderful landscape plant. Its extravagant spring floral display peaks around mother’s day with flower clusters ranging in color from white to pink with lots of variations in between. The evergreen foliage is dark green, glossy, and ornamental. Like many shrubs in the heath family (Ericaceae) this one does best in moist acidic well drained soils though it is actually fairly tolerant of dry conditions. It thrives in light shade but again, is tolerant of sunnier spaces as well.
