While my Jack's haven't reached their full potential this year, they never fail to bring on a smile. On two plants the 4th leaf to emerge was over 3 feet long, easily living up to its name. They've been happy exposed to mostly sun as well as bright shade, in well amended soil with lots of water.

Mine grew to almost five feet or so, but I may be to blame, since I planted it upside down and it had to work its way back around. When in doubt, lay it on its side! Lost growth time that way. But the leaves are a very impressive presence. Can't wait to try again this season.

They overwintered just fine through the 2014-2015 winter, which was a typical Zone 8 winter with plenty of freezes.
