24-36" x 24" wide, (cutting propagated). This English Lavender is destined for greatness. 'Royal Velvet' is very showy when blooming plants are covered with long stemmed, dark navy-blue and lavender flower spikes. The 3 to 4 inch long flower spikes, which are much longer than "Lavandula 'Hidcote'":/catalog/search/plants/lavandula+hidcote/, hold their dark color superbly as a dried flower. Home gardeners will enjoy it for its rapid growth, its long bloom period in late spring/early summer, and tolerance of wet winters. Not recommended fall planting in zones 5 and 6. Zones 5-10. 5" deep Premium pot.
