If you’d like to spend literal months enjoying flowers, Rock Steady™ vitex is meant for you! We trialed it next to other popular options and it bloomed anywhere from 6-16 weeks longer. Since it blooms on new wood, it has to grow its flower buds in spring, but once it starts flowering in late spring it doesn’t stop until fall! Its light purple, candelabra-like blooms attract pollinators and look lovely in a cut flower arrangement. It is very reliable, as it flowers on new wood. So even if it experiences winter dieback in a colder region, it should still pop back up and present flowers. Pop a Rock Steady vitex into your garden for a seasons-long floral show!

Our deciduous shrubs are entering their natural dormancy phase. As part of this process, foliage is turning colors, drying out, and falling off—this is completely normal! Shedding leaves helps the plants conserve energy and prepare for the next growing season. Rest assured, your shrubs will wake up and thrive again when it's time in your growing zone. Dormancy is how they prepare for a healthy, vibrant comeback as the seasons change!

Care: Fertilize with Proven Winners Continuous Release Plant Food in spring and mid-summer. Prune as needed in spring.
