Micro Dwarf Tomatoes (Solanum lycopersicum )
Micro Dwarf tomatoes have very small plants. Many varieties only grow to around 30 cm tall. The fruits however can be of different sizes, from cherry to beefsteak. One advantage is that they grow well in pots, which makes it easier to grow them for those who don't have much space. Many varieties can even be grown on your window sill in winter (but with lighting).
