I saw that you posted this the other day and I've been meaning to reply to it. I ordered these pineberries about 3 years ago. However I made the mistake of planting them in rather small containers (8" pots). Most died but I had 2 that have held on over the past 3 years with just a few pitiful leaves. Last fall I transplanted them into the strawberry tower. Two SMALL pitiful plants, mind you, with no more than 5 leaves between them.

That front tire is those two plants now... They have completely taken over the entire tire and are now sending runners over the side. Leaves are bushy and big, approximately 10 - 12 inches tall. HOWEVER it has produced less than a handful of flowers, none of which have created a berry bigger than my pinky nail. Disappointing but if you read the comments section on the sites that sell them you will see my experience seems to be the norm. Many people end up tearing them out and planting something else. I haven't decided if I want to use it as a trap crop, give it another year, or pull them.... I planted two Ozark Beauty on one side of that tire because I didn't realize how much those two pitiful plants were going to go overboard. The Ozark Beauty are completely engulfed and likely crowded out.... I might pull some plants just to save the Ozark Beauty which ARE producing nice berries...
