Arisaema triphyllum

 

Jack-in-the-pulpit

Arisaema triphyllum is a perennial plant growing from a corm. It is a variable species typically growing 65cm in height with three-parted leaves and flowers contained in a spadix that is covered by a hood. The outside of the hood is usually green or purple and the inside is usually striped purple and greenish white, though many colour variations exist. Grow in moist but well-drained humus-rich soil in a cool site, although it should not be too dry in summer.

Planting Outdoors

From Late Winter TO Early Spring

Plant container grown plants in deep fertile, well-drained soil in a sunny site, in late winter/early spring. Surrounding the corms and root in a mix of coarse bark, shingle and sharp sand when planting will help to prevent it rotting in a wet climate.

 

Propagation by seed or offsets

From Late Summer TO Late Autumn

Propagate by seed, sowing them in containers in a cold frame in autumn. Offsets may be removed in late summer
