Late fall, a new raised deck off the first floor was constructed over this area. Construction debris was left about throughout the winter, and only the early morning sun penetrated into this area. But the crocuses came back, diligently poking through the pieces of wood and straining to bloom again in a newly- shaded spot. I believe this is finally the year to move them. A new location must be found where they can be better-appreciated in early spring, and where they can enjoy the early spring sun and thrive.
Years ago, hybrid Dutch crocuses were planted. These had larger flowers, bloomed later, and came in more variety of colors than the species crocuses. However, these hybrids did not multiply much, and the plants and blooms shrunk more and bloomed less each year.
For The Record:
Heavy compacted soil
Partial sun, now mostly shade
Blooming: species crocus
