Genus Tagetes

Annuals , perennials , subshrubs , or shrubs [perennials], mostly 10-80(-200) cm. Stems erect , branched distally or ± throughout. Leaves cauline; mostly opposite (distal sometimes alternate) ; petiolate or sessile; blades mostly lanceolate to oblanceolate overall, usually 1-3-pinnately lobed or -pinnatisect, ultimate margins toothed or entire, faces glabrous or hairy (oil-glands scattered and/or submarginal ). Heads radiate or discoid , borne singly or in ± corymbiform arrays. Calyculi 0. Involucres narrowly cylindric or fusiform to turbinate or broadly campanulate , 1-12+ mm diam. Phyllaries persistent , 3-21+ in 1-2 series (connate to 7/8+ their lengths , usually streaked and/or dotted with oil-glands). Receptacles convex to conic, smooth or finely pitted , epaleate. Ray florets 0 or 1-8(-13+; to 100+ in "double" cultivars), pistillate , fertile (except "double" cultivars) ; corollas yellow or orange, red-brown (with or without yellow/orange), or white. Disc florets 6-120+, bisexual , fertile; corollas greenish yellow to orange, sometimes tipped with red or red-brown, tubes much longer than or about equaling funnelform throats , lobes 5, deltate to lance-linear (equal or 2 sinuses deeper than others). Cypselae narrowly obpyramidal or fusiform-terete, sometimes weakly flattened, glabrous or hairy; pappi persistent, of 2-5(-10 dissimilar, distinct or connate scales in ± 1 series: 0-5+ oblong to lanceolate, erose-truncate or laciniate plus 0-2(-5) longer, subulate to aristate . x = 12.

Species 40+: tropical and warm-temperate America, especially Mexico; introduced in Old World.

Some Tagetes species (e.g. , T. erecta) produce nematicidal thiophenes in their roots and have been shown to be effective controls for nematodes in diverse crops (cf. , http://www.ncagr.com/agronomi/nnote1.htm).Reports of "Tagetes minima L." for Pennsylvania (cf. http://plants.usda.gov) are evidently rooted in an error for T. minuta. Report of T. pusilla Kunth (= T. filifolia Lagasca) for Maryland (http://plants.usda.gov) was not verified for this treatment.[1]

Physical Description

Species Tagetes erecta

Annuals , 10-120+ cm. Leaf blades 30-120(-250+) mm overall, principal lobes/leaflets 9-25, lanceolate to lance-linear , 15-25(-45+) × 3-8(-12+) mm. Heads borne ± singly. Peduncles 30-100(-150+) mm. Involucres 10-22+ × (3-) 5-12+ mm. Ray florets (3-) 5-8+ (to 100+ in "double" cultivars) ; laminae yellow to orange, red-brown (sometimes particolored: yellow/red-brown), or white (some cultivars), ± flabellate to oval-quadrate, (2-) 12-18(-25+) mm. Disc florets (10-) 50-120+; corollas 7-12+ mm. Cypselae 6-11 mm; pappi of 0-2, ± subulate-aristate scales 6-12+ mm plus 2-4 distinct or connate , linear-oblong, ± erose scales 2-6+ mm. 2n = 24, 48. [source]

Cultivars of Tagetes erecta are widely grown in gardens and, commercially, for cut flowers. They often persist after abandoned plantings . Tetraploid plants (2n = 48) with smaller involucres and wholly or partially red-brown corollas included here in T. erecta have been called T. patula by some botanists. [source]
