Yucca filamentosa ‘Bright Edge’ – A sharply variegated Yucca with bright green strap-like leaves that are generously edged in a rich golden-yellow.

Grows 2-3′ tall by 3′ wide. Hardy to zone 4.
Yucca recurvifolia (syn. Yucca pendula) – The Curve-Leaf Yucca bears broad bluish-green leaves that have a sharp tip at their ends. The lower leaf blades often arch gracefully at the tips with mature plants eventually sloughing off the lower leaves, producing a bare trunk. Creamy-white flowers are borne on tall stems from mid to late summer. Deer resistant. Grows 3-6′ tall by 3′ wide. Zone 7.
Yucca filamentosa ‘Color Guard’ – A beautifully variegated Yucca with green leaves accented with a gold inset stripe – these are often pink or rose-tinted through spring and again in the cool late fall to winter weather.Creamy white flowers are borne on tall scapes in late summer and these are best removed when they fade. Tolerates drought. Grows 2-3′ tall by 3′ wide. Zone 4.
Yucca flaccida ‘Golden Sword’ – This Yucca cultivar bears arching foliage of bluish-green sword-shaped leaves with a bright gold inset stripe. It bears large ivory-white blooms (shown) that are fragrant, produced in late summer. ‘Golden Sword’ is an RHS Award of Garden Merit winner and works well in topdressed beds, as it produces minimal litter. 2-3′ high by 3-5′. Zone 5.
Yucca flaccida ‘Garland Gold’ (syn. ‘Garland’s Gold’) – Another beautifully variegated Yucca flaccida with bold gold centers sharply edged in a deep bluish-green. Fragrant creamy-white flowers are borne on 5-6′ tall stems in summer. Yuccas can be divided every 5 years, although this is not a pleasant task, so they are generally left alone.
