H. ‘Tower of London’

Overview

Hosta 'Tower Of London' is a cultivar of unknown origin, with no breeder or introduction year recorded in standard registration data. It is distinguished by its upright, vase-shaped growth habit and prominently veined, blue-green foliage that holds its color well into the season. The cultivar is classified as a medium-sized hosta, producing lavender flowers on tall scapes in midsummer.

In the Garden

Hosta 'Tower Of London' performs best in partial to full shade, where its blue-green leaves develop their richest coloration. The leaves are broadly ovate with a distinctly puckered texture and deeply impressed veins, giving the plant a corrugated appearance. The upright, clumping habit makes it suitable for mid-border placement or as a specimen in shaded woodland gardens. It pairs well with ferns, heucheras, and other shade-tolerant perennials that contrast with its bold foliage. At maturity, the plant forms a substantial clump, though specific spread dimensions are not documented. It is also appropriate for container cultivation in shaded patio settings, provided the pot is large enough to accommodate its root system.

Care Notes

Hosta 'Tower Of London' requires consistently moist, well-drained soil and benefits from regular watering during dry periods to maintain leaf turgor. It is moderately susceptible to slug and snail damage, which can disfigure the foliage, and deer may browse the leaves if other food sources are scarce. Fertilize lightly in early spring with a balanced, slow-release formulation. Hardiness zones are not formally established, but the cultivar is presumed to be winter-hardy in temperate climates typical for the genus.
