Baumea rubiginosa 'Variegata' (Variegated Striped Rush) - An attractive rigidly upright sedge-like plant from New Zealand that typically grows 18-24 inch tall (taller if in wet conditions) and spreads slowly on short rhizomes forming dense clumps. The 1/8 inch wide needle-like leaves (elliptical in cross section) rise perfectly straight and perpendicular to the ground, and are deep green and striped along one edge with yellow. This plant will grow in moist soils but seems to do best in loose soil with frequent to regular irrigation. Also can go into shallow water if crown is near or slightly above the surface and in these conditions can grow to up to 3 feet tall. Hardy to about 0-10 degrees F. According to the Plant List there are no longer any plants correctly called Baumea, with most previously in this genus now reclassified as being in the genera Gauhnia, Cladium or Machaerina. This species is now correctly called Machaerina rubiginosa, but we continue to list it as Baumea rubiginosa until this name gets broader acceptance. The name for the genus honors the French Chemist Antoine Baume (1728-1804). The name Machaerina comes from the Greek word 'machaira' meaning "a large knife" in refence to the shape of the leaves of the type species, Machaerina restioides. The specific epithet means rust colored, alluding to the reddish-brown flowerheads. Another common name for the species is Rusty Twig Rush. We received this interesting and attractive plant from water garden specialist Greg Speichert of Crystal Palace Perennials who got it from the U.S. National Arboretum. We have grown it since 1994.
The information about Baumea rubiginosa 'Variegata' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
