April Index

Epimedium x rubrum

Other cultivars/species:  
Other species include the parents E. grandiflorum and E. alpinum, as well as E. perralderianum, E. pinnatum, and many other species and hybrids.

Extra notes and interesting information:  

Especially suited for the woodland scene.  Also good for rock gardens, containers, and as an edging for walkways.

Cut flowers and foliage are long lasting, good for arrangements.

Tolerates heavy shade.

Cut back the leaves in late winter so that flowers will not be hidden by the foliage.

D. odora ‘Aureomarginata’ is more common and hardier than the plain leaved varieties.
