Unseasonable warm winter

I live in Denver, CO. We are having a very mild warm winter. 20 plus degrees warmer than average. I planted a ton of tulips and hyacinths this fall. How might this warm weather affect the bloom outcome. Or even worse, the bulb itself? Any thoughts?

We are too. For what it's worth, my hyacinths are coming up slightly earlier, but they are coming up. I doubt any of us know for sure till we see what happens...

RE: Unseasonable warm winter

There may be no connection at all - however - we had a very rare, lasted for days, snowfall this winter past, in mid-August. All the spring things were into putting up flower stalks. Typical zone 9 spring, then snow.

Hyacinths were fine. Tulips were hopeless. They either didn't flower or went to mush. Some daffodils didn't bother showing up at all. Seedset was patchy. Very patchy.

They can manage the warmth, but the cold bursts can throw things out of kilter, as far as I can tell.

RE: Unseasonable warm winter

In Denver also. I think the warm winter is fine - this is a little warmer than average but it's not a record-breaking warmth. Denver is Zone 5, and I'd say we have had maybe a Zone 6 winter. All tulips and daffodils I know of still grow fine in Zone 6. Also, despite the warm days it's still getting pretty cold at night, and the nights are long, meaning the cold penetrates deep so the ground is staying pretty cool throughout the day.
