It is a true prairie forb that exists across much of North America from California to Quebec. Natural populations favor rocky or fertile prairies, limestone-rich soils, roadsides and old fields. The plants have tall, upright stems and form substantial clumps. The long, fuzzy, green leaves of Maximilian's sunflower curve backwards and look as if they've been folded upwards at the ends, so water funnels across them as if from a spout. Its fuzzy green stems are flexible and strong enough to support the numerous flowers of this late season bloomer. Flowering can occur from late summer to late fall, depending on geographic location. The tall stems become lined with many single, yellow daisies with yellow or brown centers. The small to medium-sized flower heads can be quite heavy and cause the tall plants to fall over, so staking is generally required. Another option is to cut its stems back by half in early summer, which will result in shorter sturdier plants. Full to partial sun is required for good health and flowering, but this tough, adaptable plant tolerates a wide variety of neutral to alkaline soil types. In poorer, rockier soils the plants tend be sturdier and require less staking. Established specimens can even withstand periods of drought. Maximilian's sunflower is great for wildlife; its flowers are highly attractive to butterflies, and its seeds are favored by seed-eating birds. Place this substantial perennial in large garden spaces. It is also ideal for roadside plantings and wildflower gardens. The flowers are great for cutting and have a long vase-life. Plants tend to self-sow. (info source: Learn2Grow.com) Extra seeds The seeds are hand-selected. You will never receive fewer seeds than stated. We include extra seeds always as possible !
