’Big Blue’ is an evergreen perennial with tall, thin grass-like foliage with tall spikes of lavender/violet/blue, hyacinth-like blooms in late summer to autumn, followed by dark blue (almost black) berries.

Outstanding as a container plant, lush border or pathway edging, in mass plantings, and under large trees - particularly lovely when in bloom. Grasslike in appearance and habit, but not a grass at all -- actually, it’s a member of the lily family. Native to Vietnam, Taiwan, Japan, and China.
