ℹ Want to bring vibrant, tropical blooms to your cold-weather garden? The jaw dropping and highly anticipated Summerific series Hibiscus 'Edge Of Night' is a true showstopper in the landscape with its nearly jet black foliage and contrasting pink blooms that look like they belong in the tropics! Hardy all the way down to Zone 4! (-34c) Prolific and huge bubblegum pink flowers have darker veining through out. A long bloomer from summer to frost 'Edge Of Night' Hibiscus will be a star performer in your garden. Low maintenance, perennial hibiscus ('Hibiscus Moscheutos') gets cut back within a couple inches from the ground before each winter and although a later plant to break dormancy in Spring it quickly grows to its full height again each season from its roots.
