This is another easy Aroid to grow and it's readily available. It's always fun waiting for the inflorescence to pop up, a bizarre thing. The spadices I've seen are up to 18 inches long with the spathe not much shorter. The larger the tuber the larger the inflorescence...and leaf, which emerges several weeks later. This is supposed to be a stinker, which I suppose is correct given the number of flies it attracts. So far I've been growing them in dappled to full shade, as the literature suggests, but will try a few in a sunnier location this year.

The tuber shrinks considerably while producing the inflorescence and leaf and then a "new" tuber is produced. Fertile, well draining soil helps the process along. I add time release granules and occasionally use a water soluble as well. While I mulched several tubers in ground this winter, as usual I lifted most of them for dry storage in the basement. I find removing the loose "skin" on the bottom of the tuber, the left-over of the old tuber, reduces the risk of rot.

Lots of offsets are produced every year which I remove in the spring. I like to do this in the spring to minimize the number of scars on the parent tuber and hopefully the amount of water loss while it's dormant. Occasionally they'll reach flowering size in a single season.

While some growers report them as zone 6 hardy, I continue to lift most of my tubers in the fall. Many of the tubers I've left out overwinter the last few years have done fine however I wouldn't consider them reliably hardy in my climate.
