I planted 5 - 5 gallons in a row. after the first winter almost lost 2 but they recovered. Proven to be very cold hardy just bent back and covered with tarp for some winter protection nothing else. Cant wait to have a mature grove of these in Illinois !!!

Purchased a five gallon pot of Henon from on May 30, 2009. The plant was dug up and potted, then spent a few days in the car, a month in the pot and then planted in summer heat.

Don't confuse the 'nigra' term with the bamboo being black, it is not.

It is now April 11, 2010. The bamboo not only performed well, but in the last few days our miniature 'grove' has now sprouted over a dozen shoots, including several which are four feet from the initial planting. Needless to say, hubby and I looked at the number of shoots and the extent to which this small two gallon plant traveled well, thinking we may have created a monster. We are very pleased!

Update. It is now May 4, 2012. About to upload a new image to show the spread and growth of our Henon, which is filling in quite nicely!
