Cultivation instructions:

Indoor planting: Not suitable for growing indoors. Can be started off in pots inside and moved or planted outside once you see growth.

Planting outside: Ensure they are planted quite deep as doing this will protect the tubers and rhizomes from frost. Arisaema are happiest in soil conditions that are neutral to slightly acid. Cultivate soils to a depth of 20cms if possible and add plenty of grit and humus matter to the soil. Plant bulbs so that they are 10-15cms below the soil surface.

Can also look great if grown with martagon lilies, hostas or wood anemones.

Care tips:

Protect from severe frosts over winter by giving a good layer of mulch.

Remember to mark the position you plant them in as they can easily get lost.

Using bulb starter or root grow when first planting will help them to establish for future years flowering.

Hardy in UK gardens that do not become waterlogged.

Keep arisaema’s in a cool damp free area before planting
