Growing & Maintenance Tips
Best grown in dappled shade, in moist conditions. Fruiting is better in full sun, leaves are darker in some shade. Sometimes our season is long enough to allow them to self-seed, thickening the clump. Seedlings are easily removed. Prune foliage in late winter.
Notes
Almost native to Ontario.
