Cultivation
In trials in eastern Arizona, 'Frontier' and another American hybrid, 'Regal', were found to have the highest tolerance of the hot and arid climate, notably exhibiting minimal leaf scorch. However, 'Frontier' is known to have sustained winter damage where planted in the Great Plains . This failing was repeated in the elm trials conducted by the University of Minnesota, although the tree often recovered the following year. It was also criticized for its form and integrity, considered "unsuitable" for urban forestry. 'Frontier' fared better in 10-year trials at Atherton, California, to evaluate replacements for Californian elms lost to disease: "Strong structure, rapid growth rate, attractive leaf color in spring and fall, and relatively low pruning requirement suggest that Frontier has promise...", although the tree again proved only moderately tolerant of elm leaf beetles. The tree is currently being evaluated in the National Elm Trial coordinated by Colorado State University.
'Frontier' has had a limited introduction to Europe, where it is largely restricted to arboreta and elm collections; it also featured in trials in New Zealand during the 1990s at the Hortresearch station, Palmerston North.

Famous quotes containing the word cultivation:
“The cultivation of one set of faculties tends to the disuse of others. The loss of one faculty sharpens others; the blind are sensitive in touch. Has not the extreme cultivation of the commercial faculty permitted others as essential to national life, to be blighted by disease?”
—J. Ellen Foster (1840–1910)
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
“Any writer, I suppose, feels that the world into which he was born is nothing less than a conspiracy against the cultivation of his talent.”
—James Baldwin (1924–1987)
