Yucca filamentosa Adam's needle

Yucca is a fantastic plant which does resemble exotic parts of the world but is extremely hardy. It is an evergreen shrub with basal rosettes of erect, inversely lance-shaped, pale green leaves which are rigid but not sharp when touched. In second half of June it produces numerous creamy-white, bell-shaped flowers on sturdy stems, up to 180 cm tall. When in full bloom it looks like a giant lily-of-the-valley. Cut off the stem right at the base after flowering.

Yucca looks great if we let it show its architectural character. Thanks to its grass-like appearance it will combine easily with compact conifers and other evergreen shrubs with leathery leaves of various shapes and sizes. Its tropical feeling will be of use in exotic-styled landscapes and can be enhanced by mulching with white or light grey stones around.

Adam’s needle is not fussy about soil type provided it is well-drained. We also grew it in partly wet site where it does surprisingly well but does not flower. Grow it in full sun and expect it to expand by making young plants near mother plant. Unwanted plants can be easily removed and transplanted in spring or autumn. Fully hardy to -30°C (USDA zone 5), perhaps a little bit more.

TIPS for luxurious care:
Remove spent flowers as soon as possible. They may deface the plant, especially in rainy weather when they tend to rot soon. Remove any old, ill-looking leaves after winter leaving only stiff, healthy leaves for a great looking plant. If you feel that the mother plant is going down after flowering cut it off right at the roots leaving its young nursling around that will quicker become strong adults capable of flowering.
