Like most upright veronicas, this cultivar needs good drainage and consistent moisture---it is fairly sensitive to drought, but it needs good drainage too, especially for winter survival.
Deadheading finished flower spikes weekly extends the season of bloom.
The color is a light violet-blue, not the color of twilight. The spikes are long and good for cutting.
The foliage is mid-green, not silvery or gray.
In my garden, the height is more like 18" in bloom.
Will bloom from July into September if spent bloom spikes are deadheaded weekly.
Like most veronicas, this requires good drainage and consistent moisture. Not drought tolerant.
This hybrid of V. spicata and V. longifolium was bred in the Netherlands by Jan Verschoor and introduced in 2005.
