It flowers relatively early in comparison to other lilacs, often flowering mid-April at Kew, while most other lilacs flower in May.[3] The plant produces loculicidal capsules. Syringa × diversifolia is fully hardy to temperatures of -15°C.[4]
Syringa × diversifolia is a hybrid which arose at the Arnold Arboretum in 1929. Alfred Rehder, Arnold Arboretum taxonomist, noted that Syringa pinnatifolia seedlings showed that the flowers had been pollinated by a Syringa oblata growing nearby.[5]
The first clone produced, 'William H. Judd',[6] is noteworthy mainly because of its variable foliage, which may produce, entire, pinnatifid or three- to five-lobed leaves.[7] [8]
