Eryngium planum 'Jade Frost'
Jade Frost Variegated Sea Holly
This drought tolerant variegated Sea Holly is putting on quite a show this winter. Almost like sparkling snowflakes, it boasts shades of cream, powdery blue, and pink as the blooms mature. This particular Eryngium has variegated leaves at the base as well as the bracts surrounding the flowers adding to its long term interest and contrast with other plants. Eryngiums are grown for their 'everlasting' spiky flowers- they can be used fresh or dried in arrangements. They even keep their charm when left up to catch frost or snow during our winter. In the spring they can be cut to the base to clean them up. The leaf base should remain evergreen and in general they are very cold hardy plants if given good drainage. Performing best in full sun with sharp drainage and little water. A layer of gravel mulch will keep the base from rotting out during the wetter winter months. This sea holly can reach 24-30" tall and spread 15-20". A great choice for a hot, dry spot where the spiky texture and upright form can contrast with softer leafed plants like sage, artemesia or phlomis.
