This leopard lily has now had its botanical name changed to Iris domestica.  This is somewhat more accurate as it is an iris, not a lily.  Leaves look like gladiolus and grow just over a foot tall.  Flower stalks can reach 2 feet and the delicate showy flowers are orange with black dots.  The dry fruit capsules open up to reveal black seeds that look like oversized blackberries, which has earned it the nickname "blackberry lily."  It is known in China and elsewhere for its medicinal properties.  It does best in garden soil with full sun.
