Best grown in moist, organically rich, well-drained loams in full sun to part shade. Generally intolerant of soil extremes (dry or wet). Intolerant of most urban pollutants. Best sited in a location protected from high winds, but generally avoid southern exposures where the buds may be induced to open too early in late winter. This cultivar blooms about 2 weeks later than the species is accordingly less susceptible to frost problems.
