This new penstemon has very full spikes of rich purple blooms with white throats. The two foot tall stems will hold their flowers for up to eight weeks in summer. Drought tolerant, easy to grow, and attracts butterflies and hummingbirds. Remember not to cut back until spring - the foliage protects it through the winter. Penstemons are great for late summer colour so consider one, or a few, for your garden.
