Two of my favorite flowers for fall have to be helianthus and heliopsis. Both helianthus and heliopsis have a very similar look and growth habit. Though with hybridizing they are continually coming up with some interesting looks. We carry a nice selection of both in our greenhouses.
This helianthus is 4-5’ tall and blooms August through September . Its considered “the best of the genus” The flowers and leaves are small but it tends to grow into a large clump very quickly and is a vigorous bloomer.
Maximillian sunflower as it is commonly known is a tall specimen growing 5-8’ or taller. It blooms in late September or early October.
Helianthus salicifolius ‘First Light’
First Light is 4’ tall and blooms in late September into October.
Helianthus salicifolius ‘Low Down’
Low Down is new and unique in that it is short, just 18” tall. I never thought I would see one this short. With its short stature it would lend itself well to smaller gardens and container plantings.
Heliopsis ‘Summer Sun’
Summer Sun has lovely semi-double flowers strongly held at 3’ tall. It blooms late summer through fall.
Heliopsis ‘Summer Nights’
I love this heliopsis with its red stems. Its a bit more loose in growth and may be floppy in less than full sun. It tops out at 3-4’.
Heliopsis ‘Bressingham’s Doubloon’
I love this one as well with is fluffy semi-double flowers. It tops out at 4-5’ and blooms summer through fall.
