Arisarum – Mouse plant


What are my chances in growing this guy in the summer and putting it in the ground in my greenhouse for the winter? It would grow good because I have a damp and shady garden in Oak Ridges. Plan #2 bring it in the house for the winter ?
Thanks, John


Thank you for conatcting the Toronto Master Gardeners.

Arisarum proboscideum (mouse plant) is a small tuberous-rooted woodland perennial in the Arum family native to woodlands of the Mediterranean. Cousin to our native Jack in the Pulpit (Arisaema triphyllum) it produces dense clumps of long-stalked, heart- or arrow-shaped leaves and tiny spring flowers wrapped in curious hooded spathes. Mouse plant is best grown in humus-rich, moist but well-drained soils in part to full shade. Unlike Jack in the Pulpit which is hardy in our region, Mouse plant is hardy in zones 7-9 and is considered a tender perennial in our growing region.

It would survive in a heated greenhouse as long as the roots do not freeze, however, if your greenhouse is not heated my advice would be to bring it indoors before the first frost for the winter.
