Ox Eye, Sunflower Heliopsis, False Sunflower, Orange Sunflower, Hardy Zinnia

Height 24" to 30" / 60cm to 75cm
Spread 24" to 36" / 60cm to 90cm
Growth rate Fast

Environment
This plant tolerates drought. This plant will grow in dry to moist soil. Suitable soil is well-drained/loamy or sandy. The pH preference is a neutral soil.


Leaf Color Green and variegated

This plant has attractive foliage. The flowers are showy, suitable for cut flowers and suitable for dried flowers.

Culture Notes Closely resembling the true sunflower, Heliopsis frequently needs staking. However, 'Loraine Sunshine' has sturdy stems and, generally, does not need this added support. Removal of spent flowers is needed to extend the blooming period, since spent flowers normally remain attached to the plant. Division can be done in the spring, but it will be slow to reestablish this plant. Seed can be gathered in the fall. It is normally found growing in open woods, scrub, and on dry hillsides.

'Lorraine Sunshine' has gorgeous green and white variegated foliage, which provides an excellent backdrop to its large, golden-yellow daisies.
