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.

 

Geranium x 'Brookside'

Brookside Hardy Geranium (Cranesbill)

We're into the purples this month it seems and this eye-catching purple is hard to capture in a photo.  This lovely hardy Geranium has deep lavender blue flowers with a white eye that is one of the easiest perennials we have grown.  It is similar to the more familiar 'Johnson's Blue' variety but is slightly more compact at around 2' x 2' and has sturdier stems.  Soft foliage surround the everblooming flowers that seem to complement most other perennials or grasses.  The strongest bloom comes in June but it will bloom most of the summer especially if it gets cut back after the first flush of bloom.  Not many perennials get nice fall color but this one gets brilliant red and orange as it fades out into winter dormancy.  We have it on the west side of our house in full sun, where it looks best with moderate water and well draining soil, but it can be drought tolerant in part shade.  Could be deer resistant but we think the smellier Geranium varieties (Biokovo) are better for that, but let us know what you find out!  We also carry Geranium 'Rozanne' a newer variety with a compact habit and darker purple flowers.
