Whoever he bought the plants from probably just doesnt know anything about CPs..
why any CP would be considered a "companion plant" to African Violets is beyond me! although I suppose D. Capensis could be happy under the same conditions as african violets..(except with different soil and water..)
but anyway, its very clueless and irresponsible to sell CPs as "African Violet Companion Plants"
I just did a google search for ""CARNIVOROUS Drosera African Violet Companion Plants"
it brought up...Ebay.
that explains it!
