Hyacinths sprouting in November
We live in south-central Wisconsin (zone 5) and have been surprised to see our potted hyacinths (re)sprouting this week (late November). They had bloomed normally in the spring, the foliage had thrived, then died back, and the pots appeared inactive. But with sustained warm weather this past month we've seen fresh sprouts appearing. Hard freezes will probably begin here right after Thanksgiving (next week).
We have seen this phenomenon on a fairly regular basis with the small grape hyacinths in the flower beds and woods, but never before with the potted large showy hyacinths.
Is this a cause for concern? Will it significantly sap the resources of the bulbs? Can we suppress the sprouting?
Thanks in advance.
