Description:

A herbaceous perennial, with stems (to 40cm) dying back to a woody base during winter. Leaves lanceolate and with 3-5 prominent veins. Flowers are solitary, nodding, broadly campanula-like. Sepals 4, generally blue but recent introductions include alba and rosea.

Historical Background:

Aside from its compact habit and pretty flowers it is of interest to collectors because it is the only member of the Viorna Section (whose members mostly reside in North America) native to Europe. It was introduced into maintstream gardening in 1573. Since then the species has remained very popular and is used as a parent plant in hybridising processes; particularly with C. viticella. Probably one of the better hybrids to come out of these programs is “Hendersonii”.

Availability:

Species is available from the nursery now. Alba and rosea hybrids will be available late 2016.
