Firespike adds a big pop of red to any landscape, making some gardeners suggest that it's the equivalent of red salvia, but on steroids.

 

Known botanically as Odontonema strictum, firespike grows 3-5' tall and produces clusters of 3-inch-long, tubular red flowers. It grows as a herbaceous perennial in Gainesville and is coming into bloom right now!

 

The foot-long spikes of showy flowers appear year-round in South Florida and during fall and winter in Gainesville. 

 

They attract hummingbirds and several species of butterflies that feed on the nectar.

Because of its overall height and large, glossy foliage, firespike makes a great anchor when massed at the back of a garden bed. It also works well in cutting gardens.

Planting and care

Firespike can be planted year-round in gainesville, fl landscaping and will tolerate a variety of soil conditions—from slightly acidic to slightly alkaline, and from sandy to loamy. Plants should be spaced 24 to 36 inches apart.

Although it will grow in part shade or part sun, place firespike in full sun for best blooming. Once established, firespike is moderately drought tolerant.

A hard freeze can kill the above-ground growth, but the plant will typically return in the spring. Firespike often re-seeds itself and can also be propagated by cuttings.

If the plant gets too tall, you can prune it several times during the growing season or hire aGainesville landscape miantenance professional to prune them.
