Persicaria Kawagoeanum, also known commercially as Persicaria sp. 'Red', Polygonum sp. 'Kawagoneum', and mistakenly as Persicaria sp. 'Sao Paulo', is a narrow-leaved, fast-growing knotweed native to Asia. Its precise species affiliation remains uncertain. Many knotweed species thrive both in and around water bodies, often in nutrient-rich, muddy soils. Underwater, Persicaria sp. 'Kawagoeanum' displays stunning orange-red to pink hues under good lighting. The leaves, resembling willow leaves, typically reach 8 to 12 cm in length and 0.6 to 1 cm in width. In its terrestrial form, the leaves are more green.

Key Features:

  • Stunning Colors: Displays orange-red to pink hues underwater under good lighting conditions.
  • Leaf Structure: Willow-like leaves, 8 to 12 cm long and 0.6 to 1 cm wide, green in terrestrial form.
  • Growth Habit: Upright growth with moderate branching; long stems may become bare at the base and develop water roots.

Optimal Conditions:

  • Lighting: Thrives with abundant light.
  • Nutrient Supply: Requires a robust supply of macro- and micronutrients, including CO2 supplementation.
  • Water Parameters: Prefers nutrient-rich, muddy soils.

Aquarium Benefits:

  • Striking Contrast: Provides a light orange-red contrast, especially against light green plants.
  • Solitary Grouping: Best used as a solitary group in the middle ground, reaching heights of 30-40 cm.

Care and Maintenance:

  • Pruning: Pruning can lead to weak new growth; better to remove unattractive stems and replant healthy tips as cuttings.
  • Emersed Cultivation: Easily cultivated emersed in moist, nutrient-rich soil; older shoot sections will lay down and root at the nodes.


  • Aquariums: Ideal for the middle ground, adding vibrant color and texture.
  • Open Tanks, Paludariums, and Wabi Kusa: In emersed form, creates a charming, wild shrub-like appearance.
