About 3 years ago we planted several dozen crocus in our lawn. These have been starting to show up for about a week now. Not particularly early, as our yard warms up slowly.
Crocus are pretty easy way to get early spring color...plant the bulbs in the fall (a typical bulb-planting rule is to plant the bulb at a depth that's the same as 3x the width of the bulb). Just plant them and walk away.
Easy: they multiply, they return year after year, the squirrels don't seem to eat them. But the deer will nibble on the flowers.
One of the easiest gardening projects there is!
