Fanpetals (Sida spp.)
Click on terms for botanical definitions.
Fanpetals are a genus of annual and perennial wildflowers. Of the 11 species of Sida that have been vouchered in Florida, only five are native. The most common native species are common fanpetals (Sida ulmifolia) and Cuban jute (Sida rhombifolia). Flowers are usually five-petaled and pale yellow to deep yellowish-orange. Petals are often notched or lobed and may be reddish-orange at the base, particularly in S. rhombifolia. Sepals are hairy and also occur in fives. Leaves are either unlobed with serrated margins or lobed. Fruits are disc-shaped schizocarps, divided into sections that each section contain one seed. Stems may be herbaceous or woody.
Fanpetals can bloom year-round and are attractive to butterflies and moths. They occur in dry uplands as well as ruderal and disturbed areas.
Fanpetals are in the same family as hibiscus, okra, cacao and cotton.
