Calopogan tuberosus 'Fluffy'
Found in Eastern Canada as well as all of the United States to the east of the Mississippi river as a swamp grower. Likes full sun and acidic soil. I got this one from Carson Whitlow who gives a very good talk on American terrestrial orchids. With a Ph meter ($10 from eBay), I titrate a watering can of water with fertilizer to a Ph of 4.5 by adding a little vinegar. I have one other plant, Cypripedium acaule, also from the northeast, which is the only other plant that gets the acid treatment. Started out with 2 bulbs last year, now there are about 10 plantlets, only 2 will bloom. Carson says that in time, they will form a dense colony and with multiple blooms will look quite spectacular for a terrestrial plant. Check back in a couple of years.
I know fluffy Blcs and Lcs look good, I hope to some day have a colony of these guys that also grabs one's attention.
