i'm looking for antique hydrangeas?

Answer 1

Why? Is there a particular bloom form, growth habit, stem pattern, or leaf that you particularly want?

There are one or two older hybrids which are mildew resistant, but most of them that are resistant are modern hybrids. Some very modern hydrangea hybrids sometimes are remontant, which means you get a rebloom if the frost kills off some of their buds. It also means you get an another batch of bloom here in California (just now!) in addition to the early summer one.

Given how long you have to wait for them to bloom, and how long the bloom heads stay dormant and vulnerable to bad things happening to them, you'd have to want something really special about the antique ones. There's lots of different hydrangeas, so you could give us some help on what speficially you are looking for, we could answer you better.
