BUDS Terminal and axillary present, dimorphic, scattered along stem; terminal bud oblong, 3.5-10 mm long, pointed, terminal flower bud swollen at base and longer than vegetative bud; axillary buds 1 per axil, oblong, 1.5-5 mm long, pointed.

LEAVES Opposite, simple, spiral, 2 per node, spaced somewhat evenly along stem, divergent from stem. Stipules absent. Leaves petiolate, petiole furrowed, 0.6-2 cm long, glabrous or with long and unbranched hairs or with sessile scales, spreading, sparse or moderately dense, distributed throughout. Not glabrescent, eglandular, often deep red, extending into midvein. Leaf blades: abaxial surface light green or green, adaxial surface green or dark green, elliptic or ovate or obovate, bilaterally symmetric, 3-8 cm long, 1.5-5.5 cm wide, chartaceous, base acute or cuneate or obtuse, margin toothed, serrulate, apex acute or obtuse, abaxial surface glabrous or with sessile scales, reddish orange, sparse, distributed throughout or distributed along midveins, eglandular. Adaxial surface glabrous or with sessile reddish orange scales, sparsely distributed along midveins, eglandular; midvein often proximally deep red. Often reduced leaves present.
INFLORESCENCES Bisexual, compound, terminal umbelliform cyme, often orange-red scurfy throughout below ovaries except on bracteoles. Peduncle absent, inflorescence sessile. Rachis absent. Bracts sessile, linear triangular, apex acute, caducous. Pedicel 1.5-2 mm long, glabrous or with sessile scales, reddish orange, sparse or moderately dense, eglandular. Bracteoles 0 or 1, at base of pedicel or at apex of pedicel, bracteoles: abaxial surface light yellowish green or light reddish violet, linear triangular or ovate, 1-1.5 mm long, 0.5-1 mm wide, margin entire, apex acute, glabrous, eglandular, distally light reddish-violet, caducous.
FLOWERS Serotinous, formed on last season's growth, bisexual, with sepals and petals readily distinguishable from one another, 5-merous, fragrance absent. Calyx actinomorphic, tubular, of fused sepals, persistent, abaxial and adaxial surfaces light yellow or white. Sepal lobes 5, deltate, 0.5-1 mm long, 0.5-1 mm wide, margin entire, apex obtuse, abaxial surface glabrous, eglandular. Corolla actinomorphic, acetabuliform, of fused petals, deciduous, abaxial and adaxial surfaces light yellow or white, 4-7 mm wide. Petal lobes 5, very widely ovate, 2-2.5 mm long, 2 mm wide, margin entire, apex obtuse, eglandular; abaxial surface glabrous, adaxial surface glabrous. Gynoecium syncarpous. Carpels 1. Locules 3, 2 abortive, 1 fertile. Stigmas 1, 3-lobed on a short stylopodium at the top of the ovary. Styles 1, short, conical, glabrous. Ovary inferior, glabrous, eglanular. Placentation axile or parietal. Androecium alternate, epipetalous, exserted, haplostemous. Stamens 5. Anthers yellow, glabrous, eglandular. Filaments straight, white, glabrous, adnate to base of petals. For a morphological analysis of pollen see Donoghue, 1985.
FRUITS Drupe, red and green when immature, turning dark blue or black, often glaucous, ellipsoid, 9-12 mm long, 7-8 mm wide, eglandular.

Viburnum seed is slow to germinate and most species have embryo dormancy as well as seedling (epicotyl) dormancy. Germination is epigeous. Stratification at a constant 20 degrees C or a daily alternating temperature of 20 to 30 degrees C for germination followed by a low temperature pre-treatment for seedling production generally gives the best results. Seedling dormancy might be overcome by removal of the cotyledons or by a treatment of gibberellic acid (GA3). Stratification for 150+ days at 68[night]-86[day] degrees F followed by 30-45 days at 41 degrees F in moist sand or peat has given good results. Stratification for 6-8 months at a constant 20 degrees C or a daily alternating temperature of 20 to 30 degrees C in moist soil or peat has given good results. Seed can probably be stored in a sealed container at 41 degrees F with little loss of viability after one to two years.
Dried seeds can be stored at low temperature for several years. Young, 1992
