Lupine My Castle

Winner of the Royal Horticultural Society's prestigious Award of Garden Merit, My Castle Lupine displays dense racemes of rich red blooms and a fine fragrance that leaves gardeners and homeowners in thrall. Add to that, My Castle's exceptionally attractive foliage, and it's no wonder this winning perennial is so popular. Spectacular spikes of brick red create a magnificent scene in mid spring to early summer, whether exhibited in borders, cutting beds or pollinator gardens. Lupines make excellent additions to fresh floral arrangements thanks to their tall, upright habit and bright colors. The plants are easy to grow and drought tolerant. A particular favorite of butterflies and other beneficial pollinators. Plant in dry, sunny sites for best results.
