Golden Sword Yucca (Yucca filamentosa 'Golden Sword') brings beautiful color and contrast to the garden with its rosettes of yellow-centered, spiky green leaves. Especially striking at the front of the perennial border, it's evergreen and forms clumps 3-4 feet tall and 5 feet wide. A "dry" plant that tolerates drought, with good drainage it will thrive in sun or partial shade. Bonus: When mature, it bears spires of fragrant white flowers in midsummer.
