The seeds, which ripen not later than Midsummer, are round nutlets surrounded by a feathery-edged papery wing about 1 cm across. The tree is of low economic value and, unlike other European elms, the timber is not appreciated. However, viability can vary greatly from year to year, while the seed is remarkably short-lived. We investigated fruit release timing and rates, and how these are affected by meteorological variables with generalized linear models. … Germination: sow seed 1/16" deep, tamp the soil, lightly mulch the seed bed. Compared with the other European species of elm, U. laevis has received scant horticultural attention, there being only eight recorded cultivars: In Russia other ornamental forms are recognized: f. argentovariegata, f. rubra, and f. tiliifolia.

The species was never widely introduced to the United States, but is represented at several arboreta. Research in Spain has indicated that it is the presence of an antifeedant triterpene, alnulin, at a concentration of 200 μg/g {dried bark} which renders the tree unattractive to the beetles. Ulmus laevis var. Oliver Rackhamdescribes Ulmus as the most critical genus in the entire British flora, adding that 'species and varieties are a distinction in the human mind rather than a measured degree of genetic variation'.

[22], U. laevis is essentially a riparian tree, able to withstand over 100 days of continual flooding,[26] although it is intolerant of saline conditions [11] Spanish trees were found to be calcifuge, preferring slightly acid, siliceous soils, and also drought-intolerant, their xylem vessels prone to drought-stress cavitation. [38][non-tertiary source needed] This could explain the existence of the seven old specimens discovered by Elwes in 1908 on Mount Pleasant within Ugbrooke Park, Devon,[14] designed by Brown in 1761. The aim of this study was to assess the amount and distribution of variation in U. laevis populations, using both quantitative and molecular genetic approaches.
