fern asparagus 'Pyramidalis'

A tender evergreen perennial with a bushy pyramidal upright habit found in woodland edge settings where it can become invasive, also used as a house plant, in container displays and floristry for its decorative foliage. The thorny stems have bristle needle-like leaves that form triangular upright plumes, 16 to 24 inches long, with a dense fern-like feathery quality. It has air-purifying attributes. Although best known for its feathery attractive foliage, it has also small, insignificant, off-white flowers in Spring.
