Dwarf Japanese Knotweed Growing and Maintenance Tips

Grows best in an average to moist, well-drained soil, in full sun to partial shade. Holds foliage colour and flowers best in full sun, however, will thrive in drier, partly shady locations as well. Spreads semi-aggressively by underground rhizomes in optimum conditions.
