Chamaecyparis lawsoniana 'Ellwood's Nymph' is a very slow growing, globose to dwarf conical selection of Lawson cypress with soft, gray-green juvenile foliage. Because of the ultra-dense foliage, a plant can be difficult to maintain in good form in parts of the world with wet, snowy winters, as it tends to break open in harsh conditions. At maturity, a 10-year-old specimen will measure 12 to 15 inches (30 - 38 cm) tall and slightly less wide, an annual growth rate of only an inch (2.5 cm).
This cultivar originated as a seedling selected in 1983 by Douglas Loundes of MacPenny'™s Nursery, Branscore, United Kingdom. It is sometimes seen listed simply as 'Nymph'.
