At last count Oklahoma City has lost 5 independently owned nurseries in the past fifteen years. Consumers are more than happy to buy all their plants from Lowe's, Home Depot, Walmart and other big-box stores. For as long as they last, however, specialty nurseries are the ones to visit... they will have a much more diversified inventory of plants than the big-box stores. And it is always fun to find a plant no one else has.
I found two pots of Chinese Rice Paper Plant at Warren & Sons Nursery in 1999. Mr. Warren had no idea what they were or which grower had shipped them to him. I couldn't buy one fast enough. I planted it in my sisters garden and have been harvesting root shoots off of it for the past twenty years. The plant in the image is the latest off-spring. More friends and fellow gardeners want pups from this plant than from practically anything else I grow.
Chinese Rice Paper Plant is native to Taiwan... it is typically found growing on hillsides in mixed forests and shrub thickets at elevations of 100 - 2800 metres. But it is also grown extensively in several SE Asian nations. It is commonly rated as hardy to zone 8... but central Oklahoman gardeners [zone 7] have no trouble getting it back from the roots each spring.
The plant adapts well to a wide range of soil types. It also handles a wide range of soil pH ratings. It can grow in some shade or in full sun.
The Royal Horticulture Society website lists this plant... and then lists 39 nurseries you can buy it from.
I know of no American nursery carrying this plant.
If you do, I'd like to hear from you.
