Description
Heliopsis 'Sizzling Summer' lives up to its name—radiating pure sunshine with a rich palette of golden yellow to orange blooms that seem to glow even on overcast days. Each double flower bursts with layers of silky petals surrounding a warm, amber-toned centre, creating the kind of cheerful display that can lift the dullest mood. Its dark green foliage provides the perfect contrast, adding depth and texture to the glowing blooms. Standing proudly upright, Heliopsis 'Sizzling Summer' brings height and warmth to borders, containers, or even as a cutting-garden favourite—after all, who wouldn’t want a vase of summer on the kitchen table?
This lively false sunflower is as robust as it is radiant. Blooming tirelessly from midsummer well into autumn, Heliopsis helianthoides 'Sizzling Summer' offers months of colour when many plants have called it a day. It thrives in well-drained soil and full sun, rewarding gardeners with an easy, long-lasting show and an open invitation to pollinators. The strong stems and generous flowering habit make 'Sizzling Summer' a reliable garden performer that bridges the gap between late-summer perennials and early autumn hues. If your borders are in need of a touch more warmth—or you simply enjoy a plant with a bit of flair—Heliopsis 'Sizzling Summer' delivers exactly what its name promises: pure golden heat.

Useful information
-
Soak the Heliopsis 'Sizzling Summer' roots in water for 3-6 hours prior to planting
Plant your false sunflower bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
