The following seven perennials were recently selected by the Perennial Trial Garden Sub-committee as being superior after 3 years of growth and two winters. Plan to utilize these in your designs and home gardens in 2017 and I think you will be happy with the results.
WINDWALKER® Big Bluestem from Plant Select®
(Andropogon gerardii 'P003S')
This is an ornamental grass with great multi-season interest with beautiful soft blue foliage that changes to a dark maroon lavender that persists even into the winter. The plant adds impressive height to the border with a narrow growth habit that reaches about 6’ tall. This is a great choice for a xeriscape area, as it can thrive with little or no supplemental irrigation. Avoid overhead watering and over-fertilization to maintain compact plants and prevent lodging.
Alexander’s Great Brunnera from Terra Nova Nurseries, Inc.
(Brunnera macrophylla ‘Alexanders Great’ PP25,789)
