Red silk cotton tree

Native

Commonly known as Red-Silk Cotton, Silk Cotton Tree, Malabar Semul, Red Kapok Tree, Shimlo.

An imposing deciduous giant up to 25 metres tall, with a spiny, buttressed trunk and, at flowering time, an almost completely leafless crown covered in large, scarlet, fleshy flowers. The tree's silky seed fibres are the source of kapok-style stuffing material, giving it its 'silk cotton' name.

  • Sow seed fresh, without pre-treatment, for a high germination rate; if seed has dried somewhat, soaking for 12 hours first helps.
  • Sow in a sunny position, in situ or in nursery beds, sprouting takes 10-25 days.
  • Transplant seedlings once they reach about 5cm tall into individual containers, and plant out around 12 months later.
  • Half-ripe wood cuttings are another option.

Ayurveda describes the tree (called Shalmali) as cooling, sweet, and rejuvenating, its gum (Mocharas) especially valued as astringent, colour-enhancing, and useful for dysentery, diarrhoea, and blood disorders.

  • Flower buds and the calyx of unopened flowers are a valued curry vegetable, and young leaves are also cooked and eaten.
  • Ripe seeds are roasted, seed oil is extracted, and young roots, rich in starch, are eaten raw or roasted.
  • Flowers are astringent and cooling, used for skin troubles; young roots are diuretic and tonic, treating cholera, tubercular fistula, cough, urinary complaints, and impotency.
  • Gum from the tree treats dysentery, coughing blood in tuberculosis, influenza, and heavy menstrual bleeding.
  • Leaves are used to lower blood pressure and blood sugar, and, combined with various other plants in specific traditional formulas, treat enlarged spleen, oedema, and foot corns.
  • Bark is considered aphrodisiac and is used against cholera, pleurisy, stings, and toothache, and in bandages for fractures.
