Twinberry
Lonicera involucrata
  
About Twinberry (Lonicera involucrata) 22 Nurseries Carry This Plant Lonicera involucrata is a species in the Caprifoliaceae (Honeysuckle) family that is native to northern and western North America, from southern Alaska east across boreal Canada to Quebec, and south through the western United States to California, and to Chihuahua in northwestern Mexico. In California there are two recognized varieties with differing ranges. Var. involucrata has mostly yellow flowers and is found in the Sierras. Var. ledebourii has mostly red-orange flowers and is found along the coast and in the Coast Ranges from Santa Barbara County northwards. It grows at elevations from sea level to 2,900 meters. It is a large shrub that can grow 0.5-5 meter high, with shoots with a quadrangular cross-section. The leaves are elliptic, to oval-shaped, 3-16 centimeter long and 2-8 centimeter broad; they are hairy along the margins and on the underside, and have a distinctive abruptly acuminate tip. The flowers are tubular, hairy, 1-2 centimeter long, and are monoecious; they are produced in pairs subtended by a pair of reddish basal leafs 2-4 centimeter across. The fruit is a 6-12 millimeter diameter black berry containing several small seeds; it is edible but bitter and best left to the birds. In the garden this plant likes regular water but can survive on reduced watering. The flowers are welcome in summer when many other plants have finished blooming.
