Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age

Shade-Tolerant Floral Shrub
Sixteen Candles Summersweet is a deciduous shrub with ornamental features. Plant a few of these in a naturalized area, especially near a stream or water garden. Sixteen Candles would also look outstanding in that shady spot in your yard where you'd like a splash of color.
Your Sixteen Candles will amaze you with its 6-inch long spikes of delicate blossoms that reach out amid the dark green foliage in mid-to late summer. The pristine white flowers are variable in orientation, with some gently arching, upright or horizontal.
The effect of the tall, straight spikes of blooms creates an appearance reminiscent of "candles" (thus the name). Each floral spike exudes a delightful fragrance, a popular draw for your yard's pollinator. Sixteen Candles' 4-inch leaves are toothed and oblong with an ornamental, glossy sheen. Transitioning to yellow and brown hues for fall, the foliage adds one last gasp of color for your yard.
