H.B. Tukey, Jr.’s request for a better word than “ornamentals” (HortScience 22:9, Feb. 1987) is a point well taken: however, “urban plants” may or may not be an acceptable replacement. It is true that “ornamentals” does us a great disservice. Whether “urban plants” with a professional connotation would be any better would depend on its acceptance in the mind and market. A correct term is needed to qualify the essential and beneficial effects of ornamental horticulture on human beings. It must have both psychological and economic meanings.
processes depends on salinity level and length of exposure. The actual response of a plant to salinity is often affected by climate conditions, type of substrate or soil, and irrigation management in addition to growth or developmental stage. Ornamental

“Is it real?” is the usual question. Yes, pincushion protea, Leucospermum cordifolium (Salisb. ex Knight) Fourcade is the first of the ornamental proteas to be grown in quantity as a cut flower in the United States.
Registration of cultivar names of woody ornamental plants in North America (exclusive of roses, fruits, and nuts) began in 1948 under the auspices of the American Association of Nurserymen (AAN). In 1959, Arnold Arboretum assumed responsibility for the registration of woody ornamental cultivars that had not been assigned to other registration authorities. In 1980, the International Society for Horticultural Science appointed the American Association of Botanical Gardens and Arboreta (AABGA) as North American Coordinator for the International Registration Authority for cultivar names of unassigned woody ornamentals and for National Registration authorities in the United States and Canada. Arnold Arboretum (1959–1980), the U.S. National Arboretum (1981-1984), and Longwood Gardens (1984–present) have served as International Registration Authorities for cultivar names of unassigned woody ornamentals.
stress are important considerations when determining salt tolerance of individual taxa ( Hasegewa et al., 2000 ; Munns, 2002 ). Some researchers have postulated that ornamental plants are less salt-tolerant than forage or other field crops ( Amacher et

Hedychium J. Koenig is one of the largest genera of the Zingiberaceae with close to 80 species ( Gopanraj et al., 2005 ; Wood et al., 2000 ). As an ornamental, it is cultivated for its sweet-scented flowers and attractive green foliage
