They were probably hybrid seeds to begin with. The offspring would be very different with odd characteristics. Some may be nice if you give them a chance to flower.

Kayenta,

Cross pollination can happen any time you open pollinate.

Susan is spot on with hybrids. My large African hybrids I saved seeds from are not blooming either. I have had them take 12 weeks to bloom. Always a treat to see what you can get.

New to forum...I hope this response gets seen by the people who answered my question...
Thanks to you both for responding. I'll wait to see what happens!

I remember I have another question:
I live in Colo. at about 7500 feet in elevation. Very warm during summer. I bought a pink hydrangea at a garden store and it did well for about a month...but now the petals have been starting to turn a dull yellow-green and it's getting worse.
I know the hydrangea only likes a bit of sun in the a.m; too much and it wilts. It's in a big pot so I can bring it in in winter.
Any ideas on what it need to be pink and healthy again? I have NOT fertilized it yet.

Thanks!!

How much water is it getting? A couple of mine started to do that after weeks of rain. A picture would help a lot. A lot of very knowledgeable people on here that will know when they see it.

Thank you, I took a pic but I can't upload it, for some reason. I'll try again at some point.
