The Yucca Filamentosa, also known as Adam’s Needle, can be easily identified by its distinct needle-like leaves and tall, cream-colored flowers at its center. It grows best in dry and warm climates, but it can survive short, harsh winters as well. Therefore, it is best suited in USDA Hardiness Zones 4 through 10.
This plant is nearly stemless with dagger-shaped leaves that range in their color from green to blue. The flowers of the Yucca Filamentosa are edible and have a bitter taste and are often crushed and used in salads, stews, and soups.
The plant also produces a capsule fruit that is 1 to 3 inches in length. The fruit turns brown as it ripens and has many black seeds inside of it. Yucca Filamentosa does great in nearly all types of soil, but it does best in clay with a neutral pH balance.
Yucca Filamentosa is native to the southeastern United States, but it has spread to nearly all corners of the country because of its adaptability. Though a slow-growing plant, it can be cultivated easily from its seed.
