Q. Where could I buy mature ivy, helix or canareinsis, dark green?
Dear Gardener: There is a very good web site for locating nurseries local to you: Plantsourse-Where to Buy Plants in the Greater Delaware Valley Region. You could try there first. However, online is another good source: type in the botanical name, Hedera helix or Hedera canariensis and several sites will pop up with the desired plant.
