We have taken about seventeen years to get a small stock of this amazing sterile, pale blue flowered beauty. We offered them for the first time 2 years ago and we quickly sold out. Only a few will be available this year whilst we continue to increase them further. Very special. April / May 3'6" (90cm)
Planting instructions
Plant them about 5" (12cm) deep, 6-12" (15-30 cm) apart in a humus-rich, moisture retentive soil, in a sunny position, which will not dry out till mid summer.
