ASI­ATIC KNOTWEED

NZ Lifestyle Block - - A Country Life -

THIS THICKET-FORM­ING peren­nial shrub from Asia has zig-zag­ging, bluish to red­dish stems, and oval, pointed leaves on dark crim­son stalks. From De­cem­ber to April it has hang­ing clus­ters of white flow­ers that are fol­lowed by glossy brown nuts.

It grows rapidly and ex­ten­sively from rhi­zomes and mul­ti­ple stems that take root when they touch the ground, pro­duc­ing long-lived and well-dis­persed seed and can tol­er­ate a wide range of con­di­tions. The dense thick­ets it forms, es­pe­cially around wa­ter­ways, crowd out other species and block ac­cess.
