It is a large shrub or small tree growing to 8 m
tall. The leaves are arranged alternately, 12–30 cm long, and are
pinnate, with 9–17 leaflets, the leaflets 3–6 cm long, with a
sharly serrated margin. The flowers are 2–3 cm diameter, with
five white petals, and are produced in erect panicles 10–20 cm long
in mid spring. The fruit is an oval leathery capsule 5–6 cm
diameter, which splits into three sections at maturity to release the
6–18 seeds; the seeds are black, 1.5 cm diameter, resembling a
small horse chestnut seed.
The genus (which translates as "yellow horn")
is considered to be the most basal member of the family. The specific
epithet refers to the leaves, similar to those of rowans (Sorbus). It
was originally spelled as sorbifolia, but this is a grammatical error
that was corrected to sorbifolium under the ICBN.
X. sorbifolium has gained the Royal Horticultural
Society's Award of Garden Merit.
The leaves, flowers, and seeds of yellowhorn are
all edible.
