Chamaecyparis obtusa 'Pygmaea Chimo Hiba' / Pygmaea Chimo Hiba Hinoki cypress

Chamaecyparis obtusa 'Pygmaea Chimo Hiba' is a broadly globose, dwarf selection of Hinoki cypress that is very similar in appearance to Ch. obtusa ‘Pygmaea Aurescens’, but has more bronze coloration during the growing season, and the plant is more compact with thicker foliage. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) wide and 3 feet (1 m) tall, an annual growth rate of 3 to 4 inches (7.5 - 10 cm).

This is a fairly obscure cultivar that is of unknown origin. For a time it was listed and described in Don Howse's Porterhowse Farms catalog, but given its combination of Latin and Japanese terms in its cultivar name, it's likely an older plant in the nursery trade.

Humphrey Welch and Gordon Haddow speculate in their 1993 book, The World Checklist of Conifers, that 'Pygmaea Chimo Hiba' is virtually identical in appearance to the equally obscure cultivar, 'Pygmaea Densa' and maintain that the latter is an illegitimate name coined at some point in the United Kingdom.
