Harvest Tips
Bowles Blue is grown as an ornamental rather than for harvest. Cut stems for fresh arrangements during peak bloom in spring. Deadhead spent flower spikes to encourage continued flowering throughout the season. Cut back the entire plant by one-third after blooming concludes to maintain compact form and health for next season.
Fun Facts
- 🌱 Bowles Blue was selected and named by the legendary English gardener E.A. Bowles in the early 20th century, who was renowned for discovering and breeding exceptional garden plants
- 🌱 The bright blue color of Veronica flowers is so striking that they were sometimes called 'bird's eye' in old herbals, as the white centers resembled eyes
- 🌱 Unlike many speedwells that self-seed prolifically and can become weedy, Bowles Blue is much better behaved in gardens while still providing reliable color
