About Hairy Abutilon
Hairy Abutilon (Abutilon grandifolium) is recorded as an established shrub on Kauaʻi. A spreading shrub generally one to three metres tall. Its large toothed leaves have a deep heart-shaped base and conspicuous hairs. Yellow flowers have five petals around a staminal column. Dry mature fruits darken to brown or black and usually divide into ten compartments. Reported alternative host of rusts affecting native ʻilima, Sida fallax. No Kauai infection event or island loss is inferred.
