Hosta is a genus of about 70 species of shade-loving, rhizomatous, clump-forming, herbaceous perennials which are native to open woodlands, woodland margins and glades in Japan, Korea, China and eastern Russia. Hostas are primarily grown for their ornamental foliage. Stalked, conspicuously-veined, often dense, basal leaves in a variety of shapes, sizes, colors and textures rise up from a central rhizomatous crown to form a rounded to spreading mound of foliage. Bell or funnel-shaped flowers in terminal, mostly one-sided racemes bloom in late spring or summer atop vertical, unbranched, usually leafless but frequently bracted scapes which rise upward from the crown or rootstock to a point often well above the foliage mound.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.Funkia remains a popular common name today in some areas. An additional common name for plants in this genus is plantain lily (foliage is somewhat plantain-like and flowers are somewhat lily-like in some species).'Guacamole’ is a medium hosta with leaves the color of guacamole. It is a sport of H. 'Fragrant Bouquet'. It grows in a mound to 18" tall but spreads over time to as much as 50" wide. It features slightly convex, wide oval, chartreuse-gold leaves (to 11" by 8") with irregular darker bluish-green margins. Leaves are glossy above and glaucuous below with distinctive veining, mucronate tips and cordate to overlapping leaf bases. Funnel-shaped, highly fragrant, almost white flowers bloom in mid-summer on pale green scapes rising to 36" tall. Solberg 1994.
