Bolusanthus speciosus (tree wisteria) is a a small deciduous tree native
to southern Africa. In Spring it blooms with drooping, blue-mauve,
fragrant flowers hanging from the branches (Pics 3&4). Its appearance is similar
to the true wisteria, but instead it is a tree and not a vine. The tree can be trained as a bonsai, as can be seen in Pics. 5 & 6 (from internet). I offer the young seedling in Pics. 1 & 2. In Sweden, it will need protection from the cold.
