|Sambucus racemosa ssp.
sieboldiana is a deciduous shrub or small tree that grows as tall as
6m and branches well from lower parts; the branches extend as if to
draw a parabola. Leaves are of opposite phyllotaxis, of an
imparipinnate compound leaf of 8-30cm in length. The leaves on the
branches that set flowers have 2-3 pairs of leaflets, while those
without flowers have 3-6 teams. The leaflets measure 3-10cm long,
1-4cm wide, long-oblong-shaped, with sharp tips and bases round to
cuneate, and margins with fine serrations. New branch's tips give
3-10cm wide panicles and set many 3-5mm across flowers that tinge
yellow-white, occasionally light purple. Drupes mature in dark red.
