Ecology and Distribution
Flowering from May to October; fruiting from August to November.
Jasminum floridum is occurring in Gansu, N Guizhou, Hebei, Henan, Hubei, Shaanxi, Shandong, Shanxi, Sichuan of China.
Phylogeny of Oleaceae were assessed by a cladistic analysis of DNA sequences from two noncoding chloroplast loci, the rps16 intron and the trnL-F region (Wallander and Albert, 2000). Results indicated that the Tribe Jasmineae is monophyletic, but Jasminum is paraphyletic with Menodora nested within it, as Kim and Jansen (1993) and Rohwer (1996) have suggested.
Growing in slopes, valleys, woods, thickets; below 2000 m.
Jasminum floridum is planted as ornamentals.
