I fell in love with these plants in Italy a few years back. I could never get them grow up north. I put a small one in the ground here back in March. I haven't done any watering or feeding to it and it is huge. I tried to put a trellis in to hold and it has pulled the trellis down. I love the plant and it has bloomed off and on since March but sometimes you just have to be careful what you wish for.
