This morning, the birds are singing, the grass is greening and the scilla are in full, blue bloom. Scilla siberica, to be exact. This little flowering bulb reaches about 3" in height in my garden and it naturalizes beautifully. I have heard the word 'invasive' in reference to scilla but I prefer 'naturalize'. It does spread. That can be a positive. What makes one plant invasive and another a desired naturalizer? Well, this one has beautiful flowers of bright blue and they attract honeybees. It might crowd out grass but in my 'Freedom Lawn' that is just desirable. I do think its best use is as a naturalized ground cover. There is nothing as blue as the electric, black light blue of the scilla flower en masse. It blooms about the time of the daffodils and what could be better than that complement of yellow to enrich the tone of the blue or vice versa? Scilla is planted in the fall. Plan now to order some if you want your own carpet of blue. This is not a native bulb but then few are native to the USA. It is very hardy and it grows in Zones 4-8. The bulb contains a toxic substance so the deer do not eat it. That is a win around here. The bees however do love it. This plant is the first to bloom on which I see the honeybees. And, the honeybees have blue knees. Blue knees on the honeybees is a sight to see. They work the flowers as bees do and they end up with a nice cap of blue on their pollen baskets. I have long noticed the blue pollen but it was Kris Green, Interpretive Horticulurist and blog writer at Blithewold, who told me to look for the blue bee's knees. Persistence paid off. Yesterday was warm and windy and the bees were busy...well one bee was busy. I spent quite a while trying to get a shot of this busy bee. They move quickly from flower to flower wasting no time at all. I guess that is the definition of 'busy'. On my part, watching the bee was time well spent. I think there might be a children's story in that title, The Bee's Knees, what do you think?
