Heliopsis ‘Summer Sun’, False Sunflower, Oxeye, zones 3-9
If you are looking for a lot of summer color without a lot of work Heliopsis is worth considering. False Sunflowers are native from Ontario to Florida and the Mississippi. They are beautiful carefree and reliable for their very long season of bloom. Plants form a tall, bushy clump of dark green leaves, bearing branching heads of large, semi-double, golden-yellow daisy flowers with a brown centre, from early summer to early fall. Outstanding cut flower. Removing faded flowers regularly will greatly extend the blooming season. May require staking, particularly when grown in very rich garden soil or too much shade. Easily divided in early spring. Easy and always rewarding. Don't allow to dry out. Attractive to butterflies.
