Does any perennial lavish more bold blue color over such a long period than the massively popular Mizz ‘Rozanne’? I think not! From late Spring till frost, a plentitude of intense 2” blooms fill out to 3’ (or more), trailing and mingling as they go. EASY, robust and reliable, provide decent drainage and a 1” boost of compost for massive display. Cut back to 2” tall anytime. To 18” tall. May ship dormant until May.
