Maximilian’s Sunflower (Helianthus maximiliani) can grow anywhere from 3-10 feet tall and produces countless flowers throughout the late summer and fall. Maximilian’s sunflower is palatable to livestock and can be incorporated into grazing areas. This native produces a heavy crop of seed annually, which provides an important food source for birds and small mammals.
Wet and cold stratification required. Mix seeds with moist substrate (vermiculite, perlite or moss) and place in a plastic bag and refrigerate for 6-8 weeks. Sow seed at 1/8 inch depth. Do not let seedling dry out while it is establishing.
Sow directly outdoors in late fall to overwinter.
