Description: Only one Toka plum is required because it self-pollinates. Tons of pollen is produced that gives you a heavy harvest of fruit that also pollinates other plum trees. The fruits ripen in August - September. The skin is reddish-bronze and the flesh of the plum is an apricot-color. It takes extremely sweet, like candy, which is why it is sometimes called bubblegum plum.
Creamy white flowers bloom in spring giving your landscape a beautiful display. The green foliage turns burgundy-purple in the autumn. Toka plum has a vase-shaped form and medium growth rate. Any soil type is fine for this tree. It like full sun to part shade, well-drained soil, and medium moisture. Toka plum was introduced in 1911, a cross between American plum and the fragrant apricot of China.
