Arisaema

The species that we offer are hardy plants for the open garden, unless specifically noted in their individual descriptions. They will almost all be happy in light, partial or dappled shade. Again, exceptions are noted.

Soil structure is important for long-term success in Arisaema and they enjoy a fertile garden soil but one with an open, porous structure. You you can aid this by incorporating plenty of organic matter into your soil. Lime or acid is acceptable but drainage must be good. Again, organic matter worked in will create the correct open, airy, well-drained, soil structure. Provide a well-drained soil and do not bother with elaborate pockets of gravel below the tuber “to aid drainage”, in fact this simply creates a sump into which water from the surrounding soil will drain, the exact reverse of what you are aiming for.

Plant with the rounded side of the tubers facing down, the upper surface is usually flat with a small, sharp shoot pointing up. Aim to have the top of the tuber 5-10 cm below the soil surface depending on the size of the tuber (larger ones need deeper planting, smaller tubers can be more shallow in the soil).

Arisaema are available for ordering from both our Autumn and Spring lists, though the selection and range of species will vary between lists.
