Firecracker Russelia equisetiformis
Introduction
Firecracker Plant is a weeping shrub that, when
in full bloom, looks as if it is raining
flowers . These slender, red, tubular flowers
appear in the summer and hang on the plant
like little firecrackers during most of the
year. The flowers occur in 12-inch-long sprays
and are a delight to the onlooker. The slim
and pendulous branches of this plant lack
foliage; the leaves are reduced to bracts.
However, the branches and bracts are of fine
texture and have a very pleasant color. The
fruit of Firecracker Plant are small, inconspicuous,
and also hang in clusters.

Use and Management
This 4-foot-high shrub can be used as an unclipped
hedge if there is enough space to accommodate
its wide spreading habit. It is also useful as
a tall ground cover. It is quite charming in
a container or large hanging basket and is lovely
when cascading over a wall. Branches droop several
feet down the side of a container. The Firecracker
Plant is tolerant of different types of soils
as long as they are well-drained. It does require
full sun for best flowering and fullest growth.
Plants tolerate extended drought once established.
Unfortunately, plants can excape cultivation
and have been found forming thickets on disturbed
sites such as along roadsides and embankments.
Propagation of Firecracker Plant is by simple
layers and cuttings.
