Helianthus maximiliana (Maximilian Sunflower) - One of our north American native sunflowers. This plant is a wonderful large surprise for the back of the border where there is room for this beauty. From a basal cluster of foliage emerge 6 to 8 feet tall stems bearing 1 to 3 inch long lance-shaped and slightly-undulating green leaves and terminating in 3" to 4" wide bright yellow sunflowers in fall. Plant is full sun to light shade and give little to regular irrigation. The more you water the bigger it gets. Cut to the ground in late fall or early winter. Hardy into zone 4 (<-20). We received this plant from John Greenlee who received it from southern designer Ryan Gainey and grew this fun plant from 2002 to 2005. Though we no longer grow it we have plants in the nursery garden in bloom each fall. 

The information about Helianthus maximiliana displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
