Their flowers are great cut and dried too, and are produced in dense inflorescences surrounded by colorful bracts, with separate male and female plants.
The seed heads of Leucadendron are woody and cone-like - hence the common name cone-bush. About half the species store the seeds in fire-proof cones and release them only after a fire has killed the plant or at least the branch holding the cone, so many of these species never seed "in captivity."
Here are the species and cultivars we currently grow:
Leucadendron salignum "Red Tulip" Up in the brights bed this one's growing in a bit of shade - I might need to move it to a sunnier spot. 4-5 feet high and wide, with deep red bracts surrounding the cones on the branch tips.
Leucadendron salignum "Golden Tip" - Sitting at the top of the steps, this cultivar has cream and lemon yellow bracts and grows 3-4 feet high and wide.
Leucadendron "Jester" - This variegated stunner sits in the middle front bed, and sports showy variegated leaves in shades of red, cream and yellow. It'll grow to about 4' high and wide.
Common names for this plant are Silver tree, Silver leaf tree, Witteboom, or Silwerboom.
UPDATE: No thanks to the drought we lost a few of these, sadly: L. argenteum,
"Safari Goldstrike" and "Red Tulip" all bit it.
