Growing Notes

Cordylines are versatile in the garden. These upright cordylines have a clean vertical form, but also respond well to a hard pruning back (even all the way to the ground) and will send new growth out wherever they are cut back. By cutting multiple canes at different levels you can get a nice staggered effect and maximize screening.
Cordyline ‘Glauca’ also suckers from the base, creating a bamboo-like clump over time.
Once the older lower leaves dry up they can be pulled cleanly away, exposing a textured trunk.
Cordylines are an excellent choice for a pot, where they are low-maintenance plants for the long term.
In particularly windy conditions cordylines may develop brown frayed tips.

Special Interest

Most cordylines aren’t grown for their flowers, but they do occasionally bloom with pleasant clusters of fragrant white to blue-amethyst flowers.
