'Black Magic' colocasia
What the secret to growing these? I bought one last year, but all I got from it before frost was a 2" spike emerging above the ground. I really wanted this, and it wasn't cheap. It was so disappointing, I didn't even bother to dig it up last fall.
It was planted in nice soft dirt, in a very large pot; and I picked a big one (for that variety) that showed obvious life, and was planted in May.
Should I have started it indoors?
Some tender bulbs I have no luck with (like cannas: same result: all I get is a leaf spike before frost). Some are so easy (like dahlias). Start Indoors, start outdoors, I get flowers.
