The Schick hybrids are derived primarily from crosses of Harry Johnson's Paramount hybrids, created in the 1930s and 40s, and from successive crosses of their progeny. Like the Paramount hybrids, the Schick hybrids can flower several times in a season and, with increasing age, can produce greater numbers of flowers. Under the Huntington's growing conditions the first flush of flowers is typically in April with successive flushes occurring in May, June and July, and, in some hybrids, even into August, September and October. These horticultural-significant cultivars are also available through The Huntington's ISI program.
