Discussion | Solanum dulcamara is widely distributed across Eurasia and boreal North America. The North American populations are thought to be introductions, but it is possible that the species has a truly circumboreal distribution. A white-flowered form has been recognized by some authors as S. dulcamara forma albiflorum House and an especially pubescent form as S. dulcamara var. villosissimum, but variation in a number of morphological features is continuous across the range of the species and these and other variants are not recognized in the latest monograph of the group (S. Knapp 2013). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The tomato is a major agricultural crop and is commonly grown in home gardens. The fruits can have a variety of shapes, sizes, colors, and flavors and are used raw or cooked in a vast array of dishes. Other parts of the plants are considered to be poisonous. The flowers can commonly be six- to eight-merous, especially in varieties selected for very large fruits. The ancestors of Solanum lycopersicum were originally from western South America, but the species is now known only from cultivation. Tomatoes frequently escape from cultivation or germinate in compost piles or garbage dumps but are very susceptible to frost, rarely persist, and are not invasive, even in warm climates.
