The flowering and fruiting phenology and pollen activity of 9 species of Epimedium were observed, the results showed that the flowering period was distributed from early March to late May, with a flowering rate of 6.5%-46.0%, and the fruit period was distributed from midMarch to early June, with a fruiting rate of 8%-36%. There were also differences in the time and length of flowering and fruiting period among different cultivars of Epimedium, and the duration of full flowering period was different.
