Friar's Cowl: Ground Cover Plant
Arisarum vulgare
An easy, low-maintenance woodland perennial. Grow in shade to semi-shade in organically rich, well-draining soil, and keep the soil lightly moist without letting it become waterlogged -- this species is prone to root rot in soggy conditions. Water regularly through the autumn-to-spring growing and flowering season, then reduce watering (without letting the rhizome dry out completely) once the foliage dies back for summer dormancy.

Separate the rhizome into sections, each with at least one growth point.
- 3 Replant
