Arisaema candidissimum
white spathed jack in the pulpit
Unusual and eye-catching, this perennial sends up hooded, candy-pink and white spathes in early summer, striped like pyjamas and lightly scented. The flowers emerge first, followed by bold, trifoliate leaves that create a lush, exotic effect in shaded borders.
Arisaema candidissimum prefers sheltered conditions and is suitable for woodland-style planting or shaded containers. This plant is slow to emerge in spring but worth the wait. Orange berries may appear after flowering, adding late-season interest.
If planting in pots, use a loam-based compost like John Innes No. 2, as it provides better structure, moisture retention, and stability—especially important for container growing.

How to care for Arisaema candidissimum:
Plant in humus-rich, moist but well-drained soil in partial shade, ideally in a sheltered spot with protection from strong winds. It prefers dappled or or woodland-like conditions and benefits from consistent moisture during the growing season.
Mulch well in autumn to insulate the soil and protect the tubers over winter if planted in milder, coastal areas of the UK. In colder areas or if growing in a pot, move to a sheltered, frost-free place during dormancy. In spring, protect emerging shoots from late frosts, which can damage young growth. Avoid letting the soil dry out completely, even when dormant, but also ensure it's not waterlogged.
Tubers can be slow to emerge in spring, so be patient and avoid disturbing the soil. Feeding isn’t usually necessary, but a light application of balanced fertiliser in spring can support growth.
