Vitex agnus-castus “V12-2-1” (ROCK STEADY) – long-lasting flowering and extremely heat-resistant
Vitex agnus-castus “V12-2-1” (ROCK STEADY) is a vigorous, long-flowering addition to the Proven Winners® range. This well-branched and compact shrub flowers for months on end – from early summer to autumn – with graceful light blue-purple flowers. A true continuous bloomer, ROCK STEADY flowers on new wood and only forms its flower buds in spring. Once flowering begins, it does not stop
The flowers are attractive to bees and butterflies, but also particularly decorative in bouquets. In addition, ROCK STEADY is extremely robust in hot and dry conditions: a future-proof choice for both private gardens and public green spaces.
The selection was developed by Dr Carol Robacker (USA) and is marketed by Spring Meadow Nursery. In Europe, it will be introduced by Valkplant BV in 2026. Plant breeders’ rights protection is pending.
