Fully 6 wks after my first post announcing the arrival of spring, I think it has arrived for real this time. We had a month or longer revival of winter which has finally given way to spring-like temperatures. My woodland is beginning to pop. I have several corydalis species starting to flower (pics #1-3). Eranthis started 6 wks ago in some parts of my yard, just re-awakening this weekend in other areas (#4). A nice carpet of cardamine heptaphylla is blanketing an area of my woodland in lavender (#5).
#1 Corydalis nudicaulis
#2 Corydalis malkensis
#3 Corydalis solida Dieter Schacht
#4 Eranthis hyemalis
#5 Cardamine heptaphylla
