Description
Helenium 'Hot Lava' is a fiery, clump-forming perennial whose flowers open yellow streaked with red, deepen to rich crimson and then soften to burnt orange, so the plant carries several shades at once. The petals are held flat rather than drooping, giving each bloom a bold, full-faced look from midsummer well into autumn. Bees, hoverflies and butterflies visit constantly, and the sturdy stems make excellent cut flowers.

Planting & care
Help it thrive
Planting guide
Plant in fertile, moisture-retentive soil in full sun, adding plenty of organic matter to lighter soils. Space plants around 45cm apart and water in well. Avoid very dry, thin soils, which heleniums dislike.
Care tips
Keep well watered in summer dry spells and deadhead regularly to extend flowering. A Chelsea chop in late May gives bushier plants that flower slightly later. Divide clumps every two to three years in spring to keep them vigorous.
Winter care
Fully hardy. Leave the stems standing over winter for structure and wildlife if you like, then cut all growth back to the ground in late winter or early spring before new shoots appear. A mulch of garden compost in autumn feeds the soil and protects the crown.
