I love my lawn in late winter when the crocuses I've planted begin to bloom. I love seeing them, and so do the bees.
Your best bet is to plant new corms come fall and protect them with ... often six weeks after blooming. This is a sign that your crocus corms have started to enter dormancy, making them safe ...
Bulbs are one of my favorite things to grow in the garden, in side beds, or wildly in large swaths of the lawn and fields.
