Gardeners' Notes:

Positive Sneirish On Jun 2, 2008, Sneirish from Swansea, MA (Zone 6b) wrote:

At this year's local Spring Garden Show in Providence, RI there was a vendor selling tubers for "Flowering Ferns." I suspect they probably are at most of the shows around the country. Of course, I knew that ferns do not have flowers, and I have been trying to identify what the plant really was. Thanks to DG I was able to find that it was the Hardy Gloxinia. The plant is pretty, and different looking. First blooming about mid-May in my Zone 6 garden, after planting on April 13. I hope this might help someone else who fell for the sales pitch and is interested in the proper identification. By the way, they also sell "Japanese Wonder Flowers" which are Four-O'clocks.
