[1][3] The inflorescence consists of a tall floral spike whose individual flowers extend their anthers around the stem axis as in the bottle brushes.

Depending on the species, the spike consists of many densely-arranged, small flowers in shades of orange, yellow, white, pale pink or red-orange.

The blooming spike is notably tall and relatively narrow, rising from 3 to 9 or 10 feet above the foliage, depending on the species.

Plants are readily affected by winter root rot, so that a layer of sand or gravel beneath is recommended to ensure drainage.
