Light green leaves, with small clusters of light blue flowers which appear in mid-late May.
Grows about 20 cm in height. We grow this in shade / partial shade.
Described as a short-lived perennial or as a biennial. Easy to grow.
Very heavy self-seeder, a nuisance really. We clip off many of the flowers after blooming to try to limit the number of new plants the next year.
Hardy zone 3.
Glen's score: 6.
