Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). They are contrasted with nonvascular plants such as mosses and green algae. Scientific names for the vascular plants group include Tracheophyta, [11][4]: 251 Tracheobionta [12] and Equisetopsida sensu lato.
Cordyline fruticosa. (L.) A.Chev. Cordyline fruticosa is an evergreen flowering plant in the family Asparagaceae.
