The best-known species is the Siberian Pea Tree (ft arborescens), which grows up to 20 ft. high, having pinnate leaves, and clusters of yellow pea-like flowers in April and May. Other kinds not so largely grown for sale are aurantiaca, 3-4 ft.; Chamlagu, frutescens, jubata, microphylla or Altagana, pygmcea, and spinosa. Caraganas are suitable for shrubberies or game coverts, and may be raised from seeds or layers, but most kinds are grafted on stocks of ft arborescens.
