Frits are just waking up here in Maryland. Last week there was snow and single digit F temperatures. Today the first frits are appearing above ground - F. stenanthera, F. biflora and F. pluriflora. Temperatures in the 60 degree F range are predicted today and tomorrow. To put things in context, tommies and Crocus korolkowii and winter aconites are blooming, too.
