This sprawling annual (the tomato) is much cultivated, especially in warmer regions. In Ky. there are occasional escapes, but the species is not truly naturalized. Many cultivars are known (2n = 24 and 48), and the "cherry tomato" is often treated as var. cerasiforme (Dunal) Spooner, J. Anderson & R.K. Jansen (= L. esculentum Miller var. leptophyllum (Dunal) D'Arcy). That variety tends to reseed itself rather frequently within gardens, but still does not spread significantly away from gardens. Note that replacement of the "tomato" genus (Lycopersicum) into the "potato" genus (Solanum) is an excellent example of objective cladistic thought (versus sentimental attachment to distinctive fruit)!
