LEUCADENDRONS are evergreen woody perennials with growth habits that range from small trees to spreading shrubs and prostrate groundcovers.
Plants are dioecious with the female being the most useful as commercial products.

Potplant products have compact growth habits with showy foliage or cones.
Garden varieties make excellent screens or hedges.
In general LEUCADENDRONS are sensitive to Phytophthora and are best grown in sandy well drained soil. The optimum pH is 5.5 to 6.5.
LEUCADENDRONS are best planted in the autumn and no later than spring. Recommended planting density is 5000 plants per 1000m2.
HARVEST
The first harvest varies depending on the variety. Most varieties will give the first crop in year two if planted in Autumn. Some varieties are biannual and will only give a crop every second year and need to be pruned accordingly.
Plants can be harvested for approximately 10 years.
Cone products need to be sprayed for botrytis pre and post harvest.
Foliage products are susceptible to Lepidoptera damage in the spring and autumn.

Flowering time in certain varieties can be scheduled through pruning and hormone treatment.
Plants can be harvested for about 15 to 20 years.
Care should be taken when bud formation takes place that borers do not damage the developing flower buds. Leaf miner can be a problem on new growth.
