What plant gives you the biggest pain?
Inquiring minds would like to know which genera/species has proven the toughest for you to grow?
My take is that if after 3 attempts I've had it..no mas...that's it!
Aechmea zebrina for the terrestrials.
For the Tillandsias; andreana, plumosa and globosa, and believe it or not...pruinosa, a good 'ol American native and I can't grow the thing!
