Ovale was new to us in 2017 and has performed really well in the garden. It is a Japanese form of A. amurense. Not as difficult to grow as you would think, Arisaema's are unusual plants but once established in a shady spot with good drainage and plenty of leaf mould, will require little attention. They are quite spectacular plants for any garden and are easy to grow, being well suited for the UK market.
Aspect: A shady spot in the garden.
Soil type: Free draining humus rich soils that do not dry out.
