Aronia (modification of Aria, a subgenus of the allied genus Sorbus). Rosaceae. Chokeberry. Ornamental shrubs grown for their attractive white flowers and for their handsome fruits, and also for the bright autumnal tints of the foliage.
Low plants: Lvs. deciduous, short-petioled, finely and crenately serrate, glandular on the midrib above, convolute in bud: fls. in small corymbs, white; calyx 5- lobed, petals 5, spreading; stamens numerous; ovary 5-celled, woolly at the top, with 5 styles united at the base, the carpels connate but partly free on their ventral suture: fr. a small pome, flesh without grit-cells top hemispherical.—Three closely related species in E. N. Amer. Closely related to Sorbus, which is easily distinguished by the sharply or doubly serrate, often pinnate Lvs. folded in bud and without glands above, by the usually 2-3-celled ovary with the carpels connate on their ventral suture, otherwise often partly free, and by the conical top of the fr.: quite distinct in general appearance and habit and suggesting more an affinity with Amelanchier.
The aronias are small shrubs with simple deciduous leaves turning bright red in autumn and with white flowers in small corymbs followed by berry-like, red, purple or black fruit. Well adapted for borders of shrubberies and quite hardy North. A. melanocarpa is handsomest in foliage and bloom, particularly the var. grandifolia; its fruit ripens in August, but soon shrivels and drops, while A. atropurpurea and A. arbutifolia have showier and usually more numerous fruits; those of A. atropurpurea ripen in early September and shrivel at the beginning of the winter, while those of the last- named species ripen later and remain plump and bright far into the winter.
They prefer moist situations, but A. melanocarpa also grows well on drier and rocky soil. Propagation is by seeds sown in fall or stratified; also by suckers and layers, or by greenwood cuttings under glass.

The '''chokeberries''' (''Aronia'') are two species of [[deciduous]] [[shrub]]s in the family [[Rosaceae]], native to eastern [[North America]] and most commonly found in wet woods and swamps. The two species are readily distinguished by their [[fruit]] color, from which the common names derive. The [[leaf|leaves]] are alternate, simple, and oblanceolate with crenate margins and pinnate venation; in autumn the leaves turn a bold red color. Dark trichomes are present on the upper midrib surface. The [[flower]]s are small, with 5 petals and 5 sepals, and produced in [[corymb]]s of 10-25 together. Hypanthium is urn-shaped. The fruit is a small [[pome]], with a very [[astringent]], bitter flavor; it is eaten by [[bird]]s (birds do not taste astringency and feed on them readily), which then disperse the [[seed]]s in their droppings. The name "chokeberry" comes from the astringency of the fruits which are inedible when raw.

''Aronia'' is closely related to ''[[Photinia]]'', and has been included in that genus in some classifications (Robertson et al. 1991).
