Dracaena derived from the romanized form of the Ancient Greek
δρκαινα - drakaina, "female dragon", is a genus of about
**0 species of trees and succulent shrubs. [3] In the APG III
classification system, it is placed in the family Asparagaceae,
subfamily Nolinoideae (formerly the family
Ruscaceae).
It has also formerly been separated (sometimes with Cordyline) into
the family Dracaenaceae or placed in the Agavaceae (now
Agavoideae). The majority of the species are native to Africa, with
a few in southern Asia and one in tropical Central America.
The segregate genus Pleomele is now generally included in Dracaena.
The genus Sanseviera is closely related, and has recently been
synonymized under Dracaena in the Kubitzki system.
Species of Dracaena have a secondary thickening meristem in
their trunk, which is quite different from the thickening meristem
found in dicotyledonous plants and is termed dracaenoid thickening
by some authors. This characteristic is shared with members of the
Agavoideae and Xanthorrhoeoideae among other members of the
Asparagales.
D. americana, D. arborea, D. cinnabari, D. draco, D. ombet, and D.
tamaranae are commonly known as dragon trees and grow in arid
semi-desert areas. They are tree-sized with stout trunks and stiff,
broad-based leaves. The remaining species are known collectively as
shrubby dracaenas.
They are smaller and shrub-like, with slender stems and flexible
strap-shaped leaves, and grow as understorey plants in
rainforests.
Uses:
Ornamental
Some shrubby species, such as D. deremensis, D. fragrans, D.
godseffiana, D. marginata, and D. braunii, are popular as
houseplants. Many of these are toxic to pets, though not humans,
according to the ASPCA among others. Rooted stem cuttings of D.
braunii are widely marketed in the U.S.A. and the UK as "lucky
bamboo", although only superficially resembling true bamboos.
Other uses:
A bright red resin, dragon's blood, is produced from D. draco and,
in ancient times, from D. cinnabari. Modern dragon's blood is
however more likely to be from the unrelated Daemonorops rattan
palms.
How To Plant:
Dracaenas compose of a large group of popular foliage plants.
Most grow strongly upright with long, straplike leaves variegated
with white, cream, or red. Dracaenas grow well at average room
temperatures but don't like cold drafts. Give plants medium to
bright light to maintain best leaf color. Allow the soil to dry to
the touch between waterings.
