Grape hyancinths are re-blooming. What's up?

Question

After the huge downpours of last week all of my grape hyacinths are sprouting up again. Why? Does this mean they'll die and not re-bloom next spring?

Answer 1

Here's some answers:
Some top growth in the fall is normal for grape hyacinths and some other bulbs.

Don't worry about bulbs sprouting now. That happens with many spring blooming bulbs planted in the fall, when the weather conditions are right. When the temperatures turn cold, growth will stop. You'll probably notice that the leaves will turn yellow, then brown and shrivel. Not to worry. The bulb should have plenty of energy for next year's growth. In fact, a true bulb is mainly leaf material.
Usually they sprout when planted on the shallow side, and not really deep.

Don't forget to mulch the bulbs either way for the winter. Some bulbs, such as grape hyacinths, produce foliage in the fall in the first place. Don't worry about them.

Another source:
Some bulbs such as grape hyacinth routinely sprout in the fall; others may show some leaves if the fall is a long warm one. Over winter, although the foliage may become a bit bedraggled, it will not hurt the plants as long as the flower buds are not showing. Adding soil might cause them to rot. You might toss a bit of straw or other light fluffy mulch such as evergreen boughs over the area, but in most cases it isn't necessary. Of course, you will certainly need to remove any mulch layer in the spring so they can sprout normally as the weather moderates.

Good luck! Hope this helps.

Probably not die but may not bloom as well this coming spring.......depends if they will have time to restore the energy in their bulbs. So don't be pulling off the foliage until it dies back naturally. Apparently they had enough chilling last spring and were primed and ready to bloom and mistook the rains as spring weather rain. Silly plants. Try sprinkling some bone meal or superphosphate around the area to help them along.
