Growing the Florida everbearing (either from PIN or Top), and it has been great thus far. In ground over a year now, constantly fruiting. Fruits are sour until they turn totally black; then they are almost entirely sweet. Like awesome blackberries without large seed hulls to chew through.
Just cut it all down to about 6 feet, and it started flowering more aggressively. Seems like you could chop it down small every year, keep it manageable, and reap delicious berries. Not planning on letting it get big.
Have been told by someone with several varieties that the best flavor is from the Illinois everbearing. Unfortunately, after I gave away all my extra cuttings, then mine bit the dust.
