Looks like the bloom is color changing as it ages. very nice. in which website did you first see it at?

@luis_pr,

From this webpage:

Today in the Gardens – Hulda Klager Lilac Gardens

look at the October 15 2023 entry.

Nice website for that conservation project north of Portland, Dorian. Good photography as well. The only to get a duplicate hydrangea is to obtain cuttings from the shrub in the picture and identically replicate the soil nutrients and environment. If they can only figure out how to let me smell those lilacs via the Internet, they will be rich!

@luis_pr and @gardengal48 (PNW Z8/9), thank you for sharing your insights on this. I am a beginner hydrangea grower and did not till now internalize how variable hydrangeas can be based on the micro enviornment they are in. This is very helpful. I will hold off on wanting this hydrangea that it is a two-hour drive :) I did look up how to propagate hydrangeas. I am going to try that on hydrangeas I do have on hand.

My guess is a reblooming mac. They were probably late season blooms. I've never had a once blooming mac have blooms that looked that nice in the fall.

It's very common to see older, old wood flowering macs looking like that in the PNW. Mine are often still opening blooms into late summer and early fall and then fade into glorious shades of teal, pale green, mauve and rose, depending on their inseason coloring. And usually with a degree of iridescence. I often cut them then and make wreaths with the dried flower heads.
