Wir können nur durch das Vorhandensein von Symptomen, die meisten von ihnen schon vor langer Zeit und Phlox, abgeleitet von der ursprünglichen Quelle alle Instanzen von David zu schätzen wissen.

‘David’ Phlox L.P. Perry"
Origin‘David’ was selected from a population planted in beds in the parking lot of the Brandywine Conservancy, Brandy wine, Pa.,by Richard Simon (grower and owner ofBluemount Nurseries, Monkton, Md.) and F.M.
Mooberry (former horticulture coordinator, Brandywine Conservancy) in Aug. 1987. This population had been grown from native openpollinated seed collected by the Conservancy in the Brandywine Valley from unnamed varieties.‘David’ was named after David Mooberry and
given to us for subsequent evaluation and propagation.
No further crosses or selection were made."
"
Description‘David’ is a vigorous herbaceous perennial averaging
1 m in height, less in dry or sandy soils and more in moist or loamy soils.
Leaves are elliptic, glossy, dark green, and £15 cm long. Subtly sweet-fragrant flowers are 15-25 cm long panicles with individual pure-white
florets 2–3 cm in diameter. Bloom is possible for up to 6 weeks from terminal followed by lateral flowers, depending on microclimate. The average blooming date is August and September in U.S. Dept. of Agriculture (USDA) hardiness zones 4-6."
"‘David’ is also noteworthy because of its larger flower clusters, longer bloom period, stronger stems that resist toppling and thus do not need staking, and greater height than most cultivars."
"Cultivars less susceptible to powdery mildew and chemicals that control this disease are available (Daughtrey et al., 1993).
Low
susceptibility to powdery mildew was one trait leading to the selection of ‘David’, especially because several other commonly planted white cultivars, notably ‘Mt. Fuji’ and ‘White Admiral’, may be highly prone to powdery mildew."
