Sisyrinchium ‘Devon Skies’


This plant is no longer for sale directly from TERRA NOVA® Nurseries. However, it may still be available through one of our Licensees or Retail Sources.


This showy, grass-like clumper is covered with dozens of large, sky-blue flowers for weeks in early summer atop deer resistant foliage. It blooms all summer in the NE and South tolerating heat, humidity, poor soils, and drought as long it has good drainage. Super in the rock garden or front of the border. (It's sterile too!) 'Devon Skies' was found in Edmund and Rita Heaton's UK garden (the National Collection Holders for Sisyrinchium).
