Perennial bluebells overwinter
Many annuals are perennials in their homeland, but regularly freeze to death in our climatic conditions and therefore have to be sown anew every year. However, you can overwinter such specimens without any problems under cold house conditions: bluebells need a frost-free, maximum cool and dark environment of up to 10 ° C. Other, quite hardy species, however, remain in the garden and are only provided with winter protection. It is important to protect the root area in particular, as the plant will sprout from it. If the above-ground parts freeze away, this is not a big deal.
