Usually Ships in 1 to 2 Business Days
This Russian sunflower dates from 1888 and deserves the title “Mammoth”. It can grow 10' tall with 12" flowers. You can eat the seeds or they make an excellent natural bird feeder if left out for winter. Historically used by indigenous people as source of cooking oil. Just a great big old-fashioned sunflower that grows well in our northern climate.

bees love the pollen and birds love the seeds!
plant scarlet runner beans around the sunflowers and they’ll grow up the stalks...very pretty
