With its inherent resistance to drought and heat, Adam's needle basks in
sunlight.Preferred habitats are open areas such as open or thin woods, hills,
and prairies. Also bluffs and rocky or sandy coastal areas entice Adam's
needle.Adam's needle responds well to cultivation. Yucca filamentosa blends
beautifully into private and public landscapes, especially in garden or parking
lot borders and in rock gardens. Adam's needle thrives in xeriscapes (Greek:
ξήρος, xeros, "dry"), which minimize supplemental watering. Furthermore, Adam's
needle joyously accepts confinement in pots or urns. Propagation: a lover of
life As an adaptable and hardy perennial (Latin: per, "through" + annus,
"year"), thereby with a lifespan of more than two years, Adam's needle enjoys
life, which is evinced in its willingness to spread beyond the comfort zone of
its native range and habitat.Moreover, Adam's needle propagates from seeds and
from root cuttings.
Also, Adam's needle sends out communities of hardy, viable
offshoots. U.S.D.A. Plant Hardiness Zone The U.S. Department of Agriculture
Plant Hardiness Zone Map, which classes plants according to the coldest
temperature at which they remain viable, places Adam's needle in Zone 6 (-10° to
0° Fahrenheit, -23° to -18° Celsius) to Zone 10 (30° to 40° F., -1° to 4° C.).

needle looks like Long, thick underground stems firmly anchor Adam's needle deep
into the earth. Above the ground, basal leaves swirl circularly out and up to
form a rosette around a central point. Leaves are grey green or blue green.
Stiff and sword-shaped with sharp, pointed tips, leaves have a width of less
than an inch (2.5 centimeters) and a length range of almost 12 to 30 inches (30
to 76 centimeters).Long, curly, filamentous threads dance along the margins, or
edges, of the leaves. Proviso: if it looks like a sword, it might very well cut
like a sword:The sharp, pointed tips of the sword-shaped leaves, which
defensively encircle the floral stalk with its life-perpetuating seeds, are
capable of gashing and slashing with the most finely sharpened rapiers.
Certainly children should be discouraged from playing with these potentially
injurious leaves. Adults also should realize that Adam's needle leaf tips may
draw blood from even calloused bare skin.
