Hosta Frances Williams
Hosta sieboldiana is a large hosta native to Japan. It is a clump-forming perennial that typically matures in a spreading foliage mound to 24" tall and to 48-60" wide. Thick, puckered, cupped, wide-oval, green leaves (to 14” long and 12” wide) have distinctive veining, cuspidate tips and cordate lobes. Leaves often emerge smoky-blue in spring. Funnel-shaped, mostly white (sometimes lilac tinged at the base) flowers appear in early to mid summer in racemes located slightly below to slightly above the foliage atop upright leafy scapes rising to 25" tall. Plants sold in commerce today under this species name may in reality be forms of the popular H. sieboldiana 'Elegans'.Genus name honors Austrian botanist Nicholas Thomas Host (1761-1834) and was first established in 1812. The genus was subsequently renamed in 1817 as Funkia in honor of botanist Heinrich Christian Funk under the belief at that time that Hosta was an invalid name. Hosta was finally reinstated as the genus name in 1905 by the International Botanical Congress.Specific epithet honors German doctor Philipp Franz van Siebold (1796-1866) who introduced many Japanese plants into European gardens.'Frances Williams' is a popular cultivar that features very large blue-green leaves variegated with irregular greenish-yellow margins.
