Growing and caring Gomphrena Plant

  • The gomphrena plant blooms constantly all the way through summer and early fall. It is an out-crossing species that can be pollinated by bees, butterflies, and other insects. At maturity, the flowers heads of the plant are about 4 cm long and the plant grows up to 24 inches in height.
  • The plant requires very low maintenance and is almost resistant to diseases and pests. You can grow this plant very easily from seeds. To cultivate gomphrena in your garden, wait until the last average frost date for spring has passed before transplanting the seeds.
  • For both annual and perennial cultivation, soak the seeds overnight. And, the rate of germination of the seeds is low. Maturity takes place between 85 to 100 days.
  • Sow the seed 1/8th of an inch deep and scatter a few every four to six inches and then cover them lightly with soil. Throughout the growing process, cutting flowers inhibits leggy growth and also encourages further blooming.


Plant your gomphrena plant in a location where it receives full sunlight. The plant can tolerate partial shade too, but keeping the plant in sunlight makes for more vibrant blossoms. Keeping the plant in too much shade will make it lanky because of the reach for the sun.


  • Try touching the topsoil, if it feels dry, water the plant. Although the plant-like dry conditions, it is better to water the plant when they are in drought conditions and when they are young.

Before planting your gomphrena, mix a light application of a balanced organic fertilizer into the soil. During midsummer, saturate the plant with a liquid fertilizer to extend bloom time. Fertilize the plant with a balanced, slow-release fertilizer with an N-P-K ratio of 14-14-14 at the time of planting.

Vadamalli flower plants do not require much feeding, so if you mulch the soil with compost it will respond well to that too, and may not require any fertilizing.

It is not compulsory to fertilize the plant, and if you do so, make sure that the nitrogen content is low. Otherwise, the plant will grow lots of leaves but very few flowers.
