Gardeners' Notes:


On Jul 25, 2009, fullsun007 from Gainesville, FL wrote:

This is a great plant for a shady part of a garden. It can get to 3-4 feet tall with a 6" flower spike which can last almost 1 month. The flower is attractive to hummingbirds and sphinx moths. It is possible to see little roots growing right on the stalks of this plant, making propagation by cuttings very easy. It is very hardy, mine get no winter protection and endured 2 back to back nights of 21oF and came back and one has already flowered in my zone 8B yard. A great splash of color for a shady area.

Does great and grows aggressively even in hot climates like mine but benefits from afternoon shade, moist soil and misting. Produces spikes of golden-tongued flowered brachts as tall as a foot or more that last as much as 2-3 weeks if protected from wind and sun.

This plant has huge, dark green leaves and the flower is similar in appearance to it's cousin, the Brazilian Plume plant except that it is about 6-8 inches long and bright yellow. It will take more sun than the pink variety and is a much more showy plant for shady areas. It is extremely easy to grow from cuttings and I have found no major problem insects or diseases.
