I came across these Snowdrop bulbs coming into growth even though I forgot to plant them last autumn. A bulb is a storage organ so already has "food" for the growing season. I potted them up and hopefully they will settle in, flower and begin storing sustenance for the following year.
NB I have noted before that Snowdrops should be planted when freshly lifted because they do not like to dry out. That is generally true but these are Galanthus elwesii whose natural habitat is the Taurus mountains in Turkey. This species is adapted to drying out in the parched summers there which no doubt explains why they are going strong despite several months in a paper bag.
