I don't pinch - I HACK, LOL. Here's last years results of a stringy 4 inch pot that I split into four. (BTW, I had 4 little sprigs overwinter by themselves and have another jungle started this summer - I'll have to take some pics tomorrow, they're overtaking my Sunpatiens)
I was rooting the clippings in water, but for the heck of it, tried just poking them in containers here & there - worked like a charm.
I haven't grown any here of the pink and green. Have Marguarite, the chartreuse color and blackie the dark color, not heart shaped. Will have to experiment with them here in the South. Always pretty much full sun. Helene
I just pulled "Cousin It" up from my back yard. The original "potato" was planted in a pot two years ago - it was the size of a soccer ball when I pulled it up. I am sure I will have it coming up in the beds for quite a while.
We planted 1 each of these at church to cover some open dirt areas, they took over and had to be whacked back hard. When I dug the tater, one was as big as a football, the other a long snake, and the third a tiny thing. It was strange that something that small could have such a large leaf area.
