Vitex agnus-castus 'V12-2-1' (ROCK STEADY) – long-lasting blooms and heat resilience
Vitex agnus-castus 'V12-2-1' (ROCK STEADY) is a powerful, long-flowering addition to the Proven Winners® range. This well-branched, compact shrub delivers colour in the garden for months – flowering from early summer right through to autumn. As ROCK STEADY blooms on new wood, it forms its flower buds in spring and then keeps blooming non-stop once it gets started.
Its soft light bluish-purple flowers not only attract pollinators like bees and butterflies, but also look great in floral arrangements. On top of that, ROCK STEADY is highly tolerant of heat and drought – making it a future-proof choice for gardens and landscapes alike
This variety was developed by Dr. Carol Robacker (USA) and is marketed by Spring Meadow Nursery. European introduction will be handled by Valkplant BV in 2026. Plant breeders’ rights have been applied for.
