Sunflower Special

Whorled Sunflower

Whorled Sunflower (Helianthus verticillatus) is a striking native perennial known for its tall stature, narrow leaves arranged in whorls, and cheerful yellow flowers that bloom in late summer to early fall. Rising well above many garden plants, its sunny daisy-like blooms create a dramatic display while providing an important late-season nectar source for bees, butterflies, and other pollinators.

This sunflower thrives in naturalized landscapes, native plant gardens, and meadow-style plantings where it can spread into graceful clumps. Its upright form and long-lasting blooms make it an excellent backdrop plant, adding structure and movement to the garden. Despite its height, Whorled Sunflower is surprisingly sturdy and low-maintenance, adapting well to a variety of soil conditions and tolerating heat and humidity once established.

Care Instructions

Planting:
Plant Whorled Sunflower in full sun for best flowering. Space plants 2–3 feet apart to accommodate their height and spreading habit.

Watering:
Water regularly during the first growing season to establish roots. Once established, it is moderately drought-tolerant but benefits from occasional deep watering during dry periods.

Pruning:
Cut back spent flowers if desired to maintain a tidy appearance. In late fall or early spring, cut stems back to ground level to encourage healthy new growth.

Pest Control:
Generally pest-resistant, though leaf beetles or aphids may occasionally appear. Minor damage is typically cosmetic; treat with insecticidal soap if needed.

Soil Tips:
Prefers well-drained soil but adapts to clay, loam, or sandy soils. Adding organic matter improves soil health, though overly rich soil is not necessary. Mulching helps retain moisture and suppress weeds.
