It is a shame that this Veronica only blooms in the spring! Its explosive blue blooms are like an official announcement that a new growing season has begun. I also enjoy how the ground around the plant turns blue as the blooms fade and drop.
In both zone 5 and zone 6, this plant has grown vigorously for me. I use 12 inch tall border fencing to make cages for my 'Crater Lake Blue' because it can be quite floppy. It grows to hide the cage very quickly. I cut it back by about 4 inches after it blooms. Sadly, it has never rebloomed for me.

'Crater Lake Blue' is so beautiful, it's a must-have plant. Even if it only blooms for a very short time, the color of the blue makes up for it. It is a gem in the spring garden. The flowers shine and glow in the sun.
