Hi Susan!
I found a claim that "Sprainbrook Nursery" used to sell it, but they've been out of business for some time.
I wonder if this would help you propagate the plants you have left? If cuttings from adult plants won't root, maybe this would let you revert one plant or one shoot, and then take cuttings from it.

Abstract:
Plants of arborescent Hedera helix sprayed with gibberellic acid produced juvenile shoots. Juvenile characters appeared in December to March from applications of gibberellic acid made from May to July. Gibberellic acid modified inflorescences toward a vegetative condition. Previous reports that seeds of arborescent Hedera helix produce juvenile plants were confirmed. Seedlings of a variant, Hedera helix `238th Street,' which has adult-shaped leaves on a vine type of growth produced vines with lobed leaves. Heavy pruning of arborescent Hedera helix caused the production of juvenile shoots.
