A great Arisaema!

It is easy to grow; and multiplies pretty fast. The tubers can be lifted like Dahlias in frost-prone areas and stored in moist soil, in a cool room etc. during the winter. Plant it outside in early spring; or grow it in a pot indoors. Fertilize regularly.

A tuberous Arisaema from China.

Has 1, palmate, mid to deep green leaf which makes it's appearence after the spathes. Bears a pink and white striped spathe which is suprisingly (for Arisaema) quite pleasantly fragrant.

Flowers late June - August

Needs a constantly moist but well-drained, neutral to acid soil in light shade, although it will tolerate some sun. It does need cool growing conditions and doesn't tolerate heat well. It will need winter protection in frost prone areas.

Don't worry if you've spent half a fortune on a tuber and it still hasn't appeared by May. It is a lazy tuber and will often remain dormant until mid June and disappear quite quickly in the autumn.
