Arisaema amurense

Cobra lily, Jack-in-the-pulpit


Add to wishlist Remove from wishlist
Very hardy Jack in the Pulpit which is the Asian equivalent of our eastern US Arisaema triphyllum. This Jack is native to the Russian Far East, northern China and Korea and is a variable species but always has green flowers with stripes that are usually white but can be sort of a chocolate purple. Good bulb for light shade to morning sun. We sold this for some years as triphyllum ssp. pusillum before being enlightened that it is the closely related Arisaema amurense. Similar but different. An easy Jack in the Pulpit increasing nicely my offsets. Good moist soil.
