This long-blooming English introduction has attractive leaves that are entirely silvered. We looked at 'Majeste' and 'Cotton Cool' in our trials and of the two, 'Cotton Cool' never mildewed. Nice clusters of small blue flowers appear in April. A cool addition to shady areas but will take morning sun.
