Echoes, when I lived in philadelphia I missed the tropics so much, I orderded some hibiscus from a mail order garden supplier, I remember they were described as being dinner plate sized hibiscus, I did not think they would make it but I was willing to try. Same mail order had bamboo they claim would grow.
To my surprise they not only grew but were amazing, much larger really dinner plate size, and vibrant than the ones I am used to down here. When it got cold they turned into dead sticks, but, come end of next spring they flourished again, and the bamboo grew and was also beautiful, it was a major selling point when we sold the house to come back to Florida. Let me see if I can find the name of the mail order company.
