Heliopsis helianthoides 'Sunburst'

The Story

Plant Bio

Heliopsis helianthoides, commonly known as false sunflower, is an upright, clump-forming herbaceous perennial native to North America. It features sturdy stems bearing daisy-like yellow flower heads and rough, sandpapery leaves, thriving in a wide range of soils from clay to sand.

'Sunburst' is distinguished by its cream and green variegated lance-shaped foliage that provides distinct early-season interest before the golden-yellow flowers emerge. The variegation is most pronounced in cooler spring weather and naturally greens up as summer temperatures rise.

Uses & Benefits:

Cream and green variegated foliage paired with bright golden-yellow daisy-like flowers that bloom over a long summer season.

Highly adaptable to poor, clay, or sandy soils and exhibits excellent cold hardiness down to zone 4.

Attracts native bees, butterflies, and other insect pollinators, while the mature seeds provide food for local birds.

Planting

How to Grow

Plant in a location that receives full sun to partial shade, prioritizing full sun for the strongest stems and most vivid foliage variegation.
Ensure the soil is well-drained, as the root system is highly intolerant of standing water or waterlogged winter conditions.
Water regularly until the root system is established, after which the plant exhibits good drought tolerance.
Apply a balanced, slow-release fertilizer sparingly once or twice a season to prevent weak, floppy growth.

Pro Tip

Avoid over-fertilizing or over-watering this selection, as excess nutrients and moisture produce weak, etiolated stems that flop and require heavy staking.

Care Guide

Do

Deadhead spent flower heads regularly to extend the blooming window into early fall.
Prune stems back by one-third to one-half in late spring to control the plant's height and encourage a bushier habit.
Divide congested clumps every three to four years in spring to maintain plant vigor.

Don't

Do not over-fertilize, as excess nutrients lead to weak, floppy stems that require staking.
Do not plant in poorly drained sites where standing water can cause root rot.
Do not crowd the plants; ensure adequate spacing to maintain airflow and minimize powdery mildew.
