Sorry, not the Snowdrops. They are what is called 'naked' bulbs. Unlike say Daffodils or Tulips Snopwdrops do not have a coat to preserve moisture when out of the ground. They slowly dehydrate and perish. Best thing to do with them would be to find a quiet shady corner of your plot and plant them out in the soil, now. Ditto the crocus, but once the leaves and stems of them have withered, you could dig them up and dry store till Autmun.
