Growing in both full sun and part shade, however to grow at its best, locate this plant in full sun. It is sensitive to heat and does not perform well in dry conditions.
Its young branches are green and hairless. As the branches age, they become brown and woody. Its upper side of the foliage is medium green, while the underside is a pale green.
It 1/4" flowers bloom from the top downward. Flowers have 5 petals and many long stamens that surround a center ring. The ring ranges in color from orange to pink to yellow. Long stamens are fuzzy in appearance. Removing flower clusters after they are finished blooming will promote additional blooms. Pruning can be accomplished in the winter months.
