Maximilian Sunflower
Maximilian sunflower is a tall, native perennial of the sunflower family. It has lance-shaped, green leaves that grow on upright stems.
In September, each stem produces a spike of golden yellow sunflowers that bloom up the stalk. It adds a brilliant, impressive splash of color late in the growing season.
This is a good plant for hot spots and can tolerate dry conditions once established.

Performance
There is one Maxamillian sunflower growing at the Mesa Water Wise Garden and another at the Cottonwood Creek Garden. They are both large plants that bloom just before the first fall frost.
The flowers are quite attractive. It is a good plant for warm microclimates that offers color from late summer to early fall.
The brown stems can appear a little messy over the winter, so we cut them back once they're not attractive any more.
Maintenance
Cut old stems to ground level in fall or late winter before new growth starts.
