Sisyrinchium x ‘Stripey’
PRECIOUS and showy blue eyed grass. Sometimes variegation really works on a plant and this is one of those cases. Grassy leaves are soft green with prominent ivory stripes. This backdrop virtually glows in combination with the relatively large purple/blue flowers. Blooms April-July and appreciates rich soil with regular water to really get going and colonize. Excellent rain garden subject. Its best position is possibly in containers. Upright leaves have a pointed top to 6″ tall in bloom. Excellent contrast between the variegation and the flower color. Full sun. Moderate deer resistance. Showy, sweet perennial. Mix with other low perennials. Combine with Acaena inermis ‘Purpurea’ and Dianthus ‘Pink Pyrenees’. Fun to grow. Flowers close tightly at night.
