A true fire-engine red, 'Firestorm' is probably the brightest orange-red hibiscus ever grown.
The flowers are big, 7-9" across, and well presented, facing outward, for viewing on the bush.
The flowers last for 2-3 days, do not fade in the sun, and do not blacken the way many red hibiscus blooms do.
The bush itself is very pretty, with glossy leaves and a good, upright growth habit.
It blooms a lot, often with two flowers at a time.
'Firestorm' is expected it to be a typical mid-sized hibiscus that reaches 4-5 feet in height within a few years.
The flowers of 'Firestorm' show three clear rings of color in cooler, cloudier weather, an orange edge blending to red, then a fuchsia halo surrounding the eye.
In mid-summer heat and sun, the red becomes more vivid, a true fire-engine red, that takes over most of the flower.
In the hottest weather, the flower is almost completely red, with an intense color that holds up against the heat and sun.
