Maximilian Sunflower is a tall (3-8 feet) perennial sunflower with yellow flowers up to 3 inches across. This plant’s tubers were an important food source for western tribes of Native Americans. Found from southern Canada south to North Carolina, Kentucky and Texas, this plant tolerates full to partial sun, dry to moderate moisture, and a wide range of soils. It blooms from late August to October and serves as an important wildlife plant: deer forage on leaves and birds eat the seeds.

Sowing: Direct sow Maximilian's sunflower seeds in late fall, planting the seeds 1/2" deep. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before direct sowing. To start indoors, sow seeds in a flat or individual peat pots, keeping the soil lightly moist and at a temperature of 65-70 degrees F until germination, which usually occurs within 10-20 days. Keep the seedlings moist. When the weather has warmed and the seedlings are well established, transplant outdoors. This plant adapts well to clay, rocky, or shallow soil.

Growing: This plant tolerates drought, though it flourishes with regular moisture. It spreads by rhizomes and can be aggressive, especially in moist or rich soil. Deadhead the flowers for prolonged blooming. Plants growing in partial shade or moist soil will reach taller than usual heights, and may need staking or support. This plant attracts bees and butterflies.

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.


If you can’t find germinating and instructions online you can find them on the item page. Our goal is to save money everywhere we can so we can pass those savings on to you.
