Interesting Notes
Oxeye is somewhere in between Helianthus and Rudbeckia in effect. It has a shrubby habit and yellow discs and rays of some sunflowers, but the blooms are produced in great quantities on this stems above the foliage, much like Rudbeckia. It is one of the finest large summer bloomers for the garden, growing in a range of soils and forming thick, nonspreading clumps of braching stems, with toothed, opposite leaves that are clean, medium green.

Growing and Maintenance Tips
H. helianthoides is found in flood plains, fields and at woods' edge in Quebec and British Columbia south to New Mexico and Georgia. Prefers moist, well-drained soil in full sun, but may tolerate drought. Propagate by cuttings or division every 2-3 years. Staking is necessary especially in shade. Deadhead to extend the blooming season. Best utilized in the back of a border garden to accent lower growing, brightly colored perennials, as well as wildflower and cutting gardens.
