    Symphyotrichum lateriflorum (common name calico aster[1] or starved aster[2]) is a species of flowering plant in the daisy family Asteraceae, native to eastern North America. In the British Isles it is still widely referenced under its old name, Aster lateriflorus syn. A. diffusus, A. vimineus.[3]


    Growing to 120 cm (47 in) tall by 30 cm (12 in) wide, S. lateriflorum is a clump-forming herbaceous perennial with alternate, simple leaves on stiff, hairy, purplish stems. Small white or pale lilac composite daisy-like flowers are borne in corymbs up to 15 cm (6 in) across in late summer and fall (autumn).

    Like other asters, this plant is valued in gardens for providing late colour after the main flowering season has finished. The cultivars S. lateriflorum var. horizontale[4] and 'Coombe Fishacre'[5] have gained the Royal Horticultural Society's Award of Garden Merit.

    Symphyotrichum lateriflorum has been reported in British Columbia as an ephemeral that did not persist. G. L. Nesom (1994b) and J. C. Semple et al. (2002) recognized several varieties within the complex: var. lateriflorum (syn. Aster vimineus Lamarck); var. angustifolium (Wiegand) G. L. Nesom (syn. A. lateriflorus var. angustifolius Wiegand); var. flagellare (Shinners) G. L. Nesom (syn. A. lateriflorus var. flagellaris Shinners, A. lateriflorus var. indutus Shinners); var. hirsuticaule (Lindley ex de Candolle) G. L. Nesom [syn. A. hirsuticaulis Lindley ex de Candolle, A. lateriflorus var. hirsuticaulis (Lindley ex de Candolle) Porter]; var. horizontale (Desfontaines) G. L. Nesom [syn. A. horizontalis Desfontaines, A. lateriflorus var. horizontalis (Desfontaines) Farwell]; var. spatelliforme (E. S. Burgess) G. L. Nesom [syn. A. spatelliformis E. S. Burgess, A. lateriflorus var. spatelliformis (E. S. Burgess) A. G. Jones]; and var. tenuipes (Wiegand) G. L. Nesom (syn. A. lateriflorus var. tenuipes Wiegand, A. acadiensis Shinners). Much genetic and phenotypic variation is encountered within the complex; a thorough study is needed before a coherent taxonomy can be achieved.

Heads in ample, open, diffuse, ± pyramidal, paniculiform arrays, branches divaricate to long-arching or ± ascending, slender, wiry, secund; usually sessile, sometimes peduncles 0.1–1 cm+, ± pilose, bracts 1–7, linear or subulate to oblong-lanceolate, foliaceous, grading into phyllaries. Involucres cylindro-campanulate, (3.5–)4–6(–7) mm. Phyllaries in 3–4(–6) series, appressed or slightly spreading, oblong-lanceolate or -oblanceoalte (outer) to linear (inner), unequal, bases indurate 1 / 3 – 2 / 3 , margins scarious, erose, hyaline or sometimes reddish, ± ciliolate, green zones lanceolate to ± diamond-shaped, apices (outer) acute, callus-pointed, (mid) acute to acuminate, or obtuse, sometimes purplish, abaxial faces glabrous (outer), mid sparsely puberulent. Ray florets 8–15(–23); corollas white, rarely pinkish or purplish, laminae (3–)4–5(–8) × 0.9–1.2 mm. Disc florets 8–16(–20); corollas cream to light yellow turning pink or reddish purple, (2.5–)3–5 mm, tubes shorter than funnelform-campanulate throats, lobes strongly reflexed, lanceolate, 0.9–1.7 mm.
