They are also ideal for wildlife areas where their later season flowers are popular with bees and other pollinators. Some of the taller varieties can lean forward or topple in high winds and these may need staking support later in the season. They also make an excellent cut flower.

For best results grow Helenium Mardi Gras (Sneezeweed) ground cover in full sun in fertile, moist and well-drained soil.  Water regularly to prevent the soil from drying out. Deadhead any spent blooms to prolong the flowering period and then cut the plant back as it dies off in Winter. Divide congested clumps every few years, in Spring or Autumn to avoid the middle dying which can weaken the entire plant.

As a rough guide when planting Helenium Mardi Gras as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
