Sempervivum ‘Unicorn’ is a 1979 introduction from our friend, the late Crazy Ed Skrocki of Ohio. Sempervivum ‘Unicorn’ has proven to be a good grower even in our difficult, humid climate. Sempervivum ‘Unicorn’ makes a large, vigorous 18″ wide clump (in 5 years) of 5″ olive green rosettes. Good drainage is the key with all hen and chickens.
