Description

False Sunflower (Heliopsis helianthoides), also known as Early Sunflower or Sweet Smooth Oxeye, is a short-lived native perennial that brings bright yellow, daisy-like flowers to the garden from early to mid-summer. Often one of the first prairie flowers to bloom, it helps kick off the season with a long-lasting display. The blooms attract bees, butterflies, and other pollinators, and later in the season, birds may feed on the seeds.

It grows upright on slender but sturdy stems, typically reaching a few feet tall, with flowers held above the foliage in a way similar to Rudbeckia. Unlike true sunflowers and many other asters, both the center disk and outer ray flowers can produce seed, which helps it reseed and persist in plantings.

False Sunflower thrives in full sun and is highly adaptable, growing in a wide range of soils from moist areas to dry, sandy or rocky sites. Once established, it is fairly drought tolerant and easy to grow. It works well in prairies, pollinator gardens, and mixed borders, especially where you want reliable early-season color.

It pairs well with other prairie natives that bloom alongside or after it. Purple Coneflower (Echinacea purpurea) adds contrast with its bold purple petals, while Wild Bergamot (Monarda fistulosa) brings in soft lavender color and continues strong pollinator activity. Prairie Blazing Star (Liatris pycnostachya) adds vertical interest with tall spikes, and Little Bluestem (Schizachyrium scoparium) provides structure and texture while helping support surrounding plants.

Live plants are available year-round while inventory lasts and ship to all states except California, Arizona, Oregon, Washington, Nevada, Alaska, and Hawaii. After your order is placed, we’ll contact you to coordinate a spring shipping window, as many plants are overwintered and ship once dormancy breaks.

Estimated shipping for 2026 plant orders begins in mid-April, weather permitting.

PLS stands for Pure Live Seed, an industry-standard measure of seed quality. It reflects the portion of seed in a batch that is viable and capable of germinating.

What this means for you: when you purchase 1 lb. of PLS seed, the physical weight of the seed you receive will be slightly more than 1 lb. That’s because we account for non-viable seed and natural inert material upfront, so you receive a full pound of live, plantable seed.

Many companies sell bulk seed by total weight, which can include filler and non-viable seed. By pricing based on PLS, we make sure you’re getting exactly what you paid for—high-quality native seed with more predictable, successful germination.
