My healthiest Aunt Molly's Ground Cherry plant is a VOLUNTEER!
It measures to just over 8 feet across and it has nearly taken over a small flower bed, with no growth letup in sight. The main stem is nearly 1 inch in diameter.
Fruit production from the 130 intentially planted ground cherry plants is finally starting to pick up again. They've really been struggling in the heat (another record high today, 103°), but now perhaps their root systems are large enough to support the high rate of transpiration.
