Lycianthes solanum rantonetti - Blue Potato shrubs


  • This South-American plant opens masses of blue-violet flowers (with yellow stamens) throughout the Summer. It is an ideal patio or conservatory plant if one can overwinter it frost free in a conservatory or in an unheated room. The plant is not fussy to soil and is somewhat drought tolerant. It can even be shaped into a bonsai. It may reach 1-2m in height in a larger container and can be trimmed, however it is also good to leave some stems to grow as the flowers prefer to develop around the end of the stem.
