A most outstanding hybrid lily known worldwide for its hardiness, vigor, and overall dependability in the garden. ‘Scheherazade’ was one of the first interspecific hybrids introduced on the market and began a trend that would revolutionize the world of lily breeding. Bred by L. Freimann using tetraploid (double the number chromosomes a plant typically has) forms of a cultivar called ‘Thunderbolt’ and a tetraploid form of the famous ‘Black Beauty’, you get a most unusual mahogany crimson edged in gold and later fading to cream born in profusion over stalks that have often been referred to as “Lily Trees”. 

It’s finally beginning to feel like summer; fairly consistent warm temperatures, scrambling to get containers adequately watered, and gravitation towards shade when working outdoors!
The past few weeks have been so busy and incredibly productive as we’ve been fortunate to have an arsenal of interns, work study students, and volunteers help us out in grounds several times a week this summer.
