Sorbus helenae is one of the rarer rowan species, its leaves are larger than other rowans, but with fewer leaflets, giving it a distinctly different appearance.
Dense clusters of white flowers appear in early summer, and are followed by clusters of pink-speckled white fruitlets. The size of the flower clusters tends to be larger than other rowan species.
The leaves also take on orange and red hues in the autumn.
Unusually for a rowan, Sorbus helenae also has some winter interest, with pink-tipped buds showing against the bare branches.
