Monrovia® Sienna Heuchera is an evergreen herbaceous perennial with a mounding habit grown for its dramatic basal and vibrant foliage.  The round-lobed leaves emerge green with dark orange veining that matures to yellow with the veining gradually expanding until the center is orange with only a fine yellow edging.  Airy clusters of tiny bright pink bell-like flowers bloom on pink spires in summer attracting butterflies.  Blooms best in partial sun and moist well-drained soils.  The Northern Exposure series is rust resistant.
