Rainy Side Notes
Found growing on moist, limestone cliffs and next to streams, Epimedium davidii is a native of western Sichuan Province, P.R. China. It tolerates our acidic soils even though its nativity is on wet, limestone cliffs.
The demure E. davidii spreads slowly, eventually reaching two feet across in five years. A mass planting of this charming perennial, under trees or shrubs, makes an appealing effect. Its main flush of blooms is in mid spring to early summer; however, by keeping your plants well watered and rich in organic matter, you will be rewarded with flowers throughout the season.
