Siam Splash - Tropical Flowering Curcuma

Growing Flowering Curcuma

Curcuma is easy to grow. Siam™ Splash Curcuma loves warmth and is happiest during spring and summer. The bulbs of the plant (called rhizomes) are edible. The plant is Curcuma, the herb is turmeric and the active ingredient in the herb is curcumine. The Curcuma has an exotic appearance and can be recognized by its large extravagant flowers and long bracts. This stately plant has strong slender stems, large arching leaves and flowers that appear in profusion. If you look closely, however, what look like flower petals are actually bracts that accommodate many tiny flowers. A Curcuma can produce 2 to 5 new flowers, each of which lasts for about 3 weeks.

Care Tips for your Curcuma

  • Light - 6+ hours of direct sunlight per day is ideal.
  • Blooms - Vibrant blooms, dense spikes of clustered flowers.
  • Colours - Available in shades of pink.
  • Water - Water once to twice per week - only water when the soil is dry to touch. If your Curcuma gets brown leaf tips, this is a sign that the soil is too dry.
  • Size - This plant grows 45-60 cm (18-24”) in height.
  • Fertilizer - For best results use a balanced liquid fertilizer every 2 weeks.
  • Deadheading - Remove spent flowers and seed pods to promote blooming (see image below).
  • Tips - When receiving sufficient light, water and nutrients, a flower will remain in bloom for about 3 weeks. Once the flower has faded, cut the flower stem as close to the soil level as possible so that the plant can devote all of its energy to a new flower.
  • Other - Treat as annuals in cooler climates - they will not survive a frost but can be overwintered indoors. Once the blooming period is over they become dormant. Pruning helps maintain a nice shape and size and this will also encourage a fuller plant.

    Outdoor Care
    Outdoor curcuma flourishes best in warm and sunny places. The plants will be enjoyable in container gardens or freely planted in beds in the garden.

    Indoor Care
    Curcuma prefers a light, sunny location – on a window sill, for example. A spot directly over the radiator is no problem. At a minimum temperature of 15° C, you can also put your Curcuma outside on the balcony or in the sunroom, but just be sure that no water settles in the cavities formed by the bracts since the Curcuma cannot tolerate this.

    Deadheading is the removal of spent blooms and seedpods. Removing faded blooms will help to promote further blooming by directing the plant's energy to produce new blooms. When receiving sufficient light, water and nutrients, a curcuma flower will remain in bloom for about 3 weeks. Once the flower has faded, cut the flower stem as close to the soil level as possible and discard. so that the plant can devote all of its energy to a new flower. A Curcuma plant can produce 2 to 5 new flowers so that you can enjoy it for a long time.
