Codiaeum variegatum Zanzibar....maybe?
Quote from www...."The Zanzibar Croton (Codiaeum variegatum 'Zanzibar') is a striking, slow-growing tropical shrub famous for its vibrant, ribbon-like leaves. Featuring a brilliant blend of lime-green, gold, orange, red, and deep burgundy, its fine, grass-like foliage adds dramatic texture and contrast to any space."
