Cerinthe major purpurascens
25 Seeds |
Sometimes referred to as 'Blue Kiwi' and 'Pride of Gibraltar', the Blue Shrimp Plant is one of the most asked for different plants for the garden. Its almost steel blue-green foliage and sensational deep blue bracts and small purple flowers make a wonderful impact in the garden. Early in the season this unusual plant resembles a garden pea but as the stems lengthen, they branch to produce showy blue flower bracts with small purple bells that seem to grow out of the leaves and stems. Very attractive to bees. Heat tolerant throughout the summer and also hardy down to at least 23 degrees F. Cooler nights in fall produce an even deeper blue color. While technically an annual, this self-sowing hardy plant will drop its large pea sized seeds throughout late summer and early autumn and will grow in and around the same patch for quite some years. Growing to approximately 18-24 inches tall, this rare heirloom variety is a subtle but beautiful plant that is quite easy to grow and low maintenance. Biennial to tender perennial with blue-green foliage growing to a height of 16-24". Plant in full or partial shade in a well drained soil and deadhead frequently to encourage repeat flowering. Hardy zone 7-10.

A half-hardy perennial that freely reseeds, in all but the warmest parts of North America it should be considered an annual.
