Spring bulbs growing in Fall???

Champaign, IL(Zone 5b)

I have some spring bulbs(daffs, crocus, tulips, grape hyacinths, hyacinths....) in a shade garden. I just noticed that there are some that are starting to sprout again. They had all completely died back and there was no foliage. Based on the location and and leaves, its not the crocus or hyacinths...it could be grape hyacinths or daffs. Either way, I thought they were spring bulbs...they bloomed this spring, so what are they doing now? The temps have been hot, then we had a few cooler days(mid to upper 80s) and that's when I noticed them. What's going on?

Thanks for any help!

I've had that happen with my daffs. After it's been real hot and then cools down to the 80's, it fools the bulbs into sprouting again. Mine usually just grow a couple of inches and then quit. They will die back again when it gets good and cold and they'll be back to normal come spring. It's never had an adverse affect on mine.

Muscari/grape hyacinths send out leaves late in Summer, it is normal.

Ahhh...that's good to hear...thanks guys...I've never had it happen before...of course this is my first year with daffs...I had grape hyacinths before, but they were old...I just planted new ones last fall. That must be it. Good to hear they'll be ok. Thanks a lot!

Hi Kristie

Yes, I too have muscari bulbs with a couple of inches of new growth again this Sept. (it also happened last yr) My leaves stayed somewhat green under the snow last winter & then the normal Spring growth on top of that made for a mass of foliage but still got lots of blooms. I had intended to thin the bulbs out this fall & still hope to find the time to do it so maybe the leaves won't be quite so dense & fall all over the lavender. Are your new bulbs the ones that are sprouting? Am wondering if this happens because of crowding?

Yes, I think it is the new bulbs that are sprouting...however, they are definately not crowded. Everything is spaced out about 6-12 inches apart( I keep getting a few bulbs each year and adding them; the bed is pretty long). Right now it is in shade because it is under a tree. However, the ones that are sprouting are on the side that gets some evening sun. So far I haven't seen any on the East side of the bed that have sprouted. Other than that, I don't know what the difference would be.....

Hi Kristie,
There is an article from the Aug.26 Chicago Tribune (Home & Garden section, page 6) that talks about shrubs at the Morton Arboretum and Chicago Botanic Gardens that are putting out spring blossoms on plants that already have fruit from last spring's blossoms. Quoting from the article:

"The heavy rains seem to have startled these shrubs into sudden activity after the long dry spell in May and June sent them into a winter-like slowdown. They've been fooled into thinking it's spring."

As Naturelover previously stated, that might be what's happening to your bulbs.

Interesting....thanks for sharing that....who knew?! I've noticed that almost all of them have sprouted(its only one type of flower). Good to know they'll be ok for next spring though.

Just noticed my grape hyacinths today. They are about 2 inches tall. The weather has not cooled down nor have we had much rain. Did the same last year & scared me. They didn't do exceptionally well this year but our spring weather was so messed up I'm surprised they bloomed at all. Anyway, I think it's normal.

Good to hear this is normal...I thought I'd done something wrong!

I didn't know there were flowering crocus in the fall! I bet that's what they are. Cool
