Flowering at an amazing 8 feet in height, Flower Tower, fills the tall herbaceous border with masses of large clear yellow daisy flowers with inky dark centers from very late summer and into fall. Stout stems support the flowering display without need for staking and the plant is insect and disease resistant. It is important to plant in full sun, average soils and apply only low levels of fertilizer throughout the growing season. Pollinating insects are drawn to the flowers and songbirds follow up for the seeds.
