Adam's Needle features bold spikes of creamy white bell-shaped flowers rising above the foliage from mid to late summer. It has attractive grayish green foliage. The sword-like leaves are ornamentally significant but remain grayish green through the winter. The fruit is not ornamentally significant.
Adam's Needle is a multi-stemmed evergreen shrub with tall flower stalks held atop a low mound of foliage. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.
This shrub will require occasional maintenance and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;
Adam's Needle will grow to be about 30 inches tall at maturity extending to 5 feet tall with the flowers, with a spread of 3 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.
This shrub should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution.
This species is native to parts of North America.
