Bear's Breeches
Acanthus mollis
Acanthus mollis, commonly known as Bear's Breeches, is a herbaceous perennial known for its bold foliage and striking flower spikes. It typically grows to about 1-1.5 meters tall and wide. The plant features large, deeply lobed, glossy green leaves. Tall spikes of hooded, white or purplish flowers emerge in summer. While primarily an outdoor plant, some attempt to grow it indoors, but success is limited due to its need for bright light and space. It is grown for its architectural foliage and unique flower structures.
Liriope
Liriope muscari
Liriope muscari is a grass-like perennial plant typically grown as a ground cover. It features clumps of arching, strap-like, dark green leaves. It is primarily an outdoor plant, valued for its low maintenance and ability to thrive in various conditions. It produces spikes of small, lavender to purple flowers in late summer, followed by black berries. While occasionally grown indoors, it requires very bright light and consistent moisture to thrive, making it challenging to maintain as a houseplant. People grow it for its evergreen foliage, erosion control, and ornamental flowers.
