Lucy : I have discovered that also. I have plants appearing I thought were done for.
Daffs seem to have multiplied and a oriental poppy that withered in last summers drought ,is putting up a decent bunch of leaves.
Here is what's blooming now:
Redbud second year since planting and blooming like crazy.
Corydalis is popping
I think this is White Medal double daff. It's part of a mix.
