Common Name: Corkwood
Leitneria floridana is a deciduous shrub that can grow up to 6.00 metres tall.
It is harvested from the wild for local use as a source of materials.
South-eastern N. America - Florida to Texas and Mississippi.
Borders of swamps and wet ground[
], also on muddy saline shores[
]. Open or forested swamps, wet thickets, roadside ditches, saw-grass-palmetto marshes, estuarine tidal shores[
Requires a moist lime-free humus-rich soil[
], succeeding in badly-drained soils[
]. Plants grown in Britain tolerate drier conditions than their native habitat, but they still require plenty of moisture[
Plants are hardy as far north in America as Boston, Massachusetts[
]. They are unlikely to be fully hardy in all parts of Britain.
Plants produce suckers[
]. Vegetative reproduction is predominant, forming large clones from adventitious buds on shallow roots[
Dioecious, male and female plants must be grown if seed is required.
Wood - very light, soft, close grained. The layers of annual growth are hardly distinguishable[
]. This is one of the lightest known woods, it weighs about 12½lb per cubic foot, is lighter than cork and is used for floats etc[
The seed germinates better if it is given 3 months cold stratification so is probably best sown in the autumn in a cold frame. The seed can also be sown in late winter in a greenhouse but the germination is variable[
]. Prick out the seedlings into individual pots as soon as they are large enough to handle. Young plants should be overwintered in a greenhouse for their first year and can then be planted out in late spring after the last expected frosts[
]. Give some winter protection from the cold for their first year outdoors.
