Maximilian's Sunflower Seeds – 50 Helianthus Maximiliani Native Perennial Wildflower

Maximilian's Sunflower (Helianthus maximiliani) is a tall, native perennial wildflower prized for its brilliant golden-yellow blooms and late-season display. Growing on sturdy, upright stems, it brings dramatic vertical interest to meadows, prairie plantings, pollinator gardens, and the back of perennial borders. Its cheerful flowers open in late summer and continue into autumn, providing a valuable nectar and pollen source when many other plants have finished blooming.

This hardy North American native is well suited to naturalized landscapes, wildflower meadows, and low-maintenance gardens. Its tall, clump-forming habit and abundant blooms make it a standout choice for gardeners looking to support bees, butterflies, and other pollinators while adding reliable color to the landscape.

Planting & Care

Sow Maximilian's Sunflower seeds indoors 4 to 6 weeks before the last frost, or direct sow outdoors after the danger of frost has passed. Press seeds lightly into the soil surface and keep them moist but not waterlogged. Germination typically occurs in 10 to 21 days at temperatures around 65 to 75°F. Once seedlings have several sets of true leaves, transplant them outdoors after hardening off.

Choose a sunny location with well-drained soil. Water regularly during the first growing season to help plants establish a strong root system. Once established, Maximilian's Sunflower is relatively low-maintenance and drought-tolerant. Tall stems may benefit from staking in windy, exposed sites. Divide clumps every few years to maintain vigor and prevent overcrowding.
