| Section class | II-2 (Large) |
Overview
Registered in 2013, *Hosta* 'Jetstream' is an open-pollinated seedling of unknown parentage, notable for its intensely powder blue-green leaf margins and heavy glaucous bloom on both leaf surfaces. This large cultivar forms a dense, mound-like clump with broadly ovate, cordate-based leaves that display mild puckering on the upper surface and moderate corrugation.
In the Garden
'Jetstream' reaches a mature height of 26 inches (66.0 cm) with a spread of 40 inches (101.6 cm), making it suitable for mid-border or specimen placement in partial to full shade. Its blue-green foliage pairs well with golden or chartreuse companions such as *Hosta* 'Sum and Substance' or *Carex elata* 'Aurea'. The moderate growth rate and substantial leaf size suit woodland gardens, shade borders, or large containers.
Care Notes
Provide consistent moisture during dry periods, particularly in the first growing season, and apply a balanced slow-release fertilizer in early spring as new shoots emerge. The glaucous bloom may be susceptible to slug damage; monitor regularly and apply barriers if necessary. Typical hosta-growing zones apply.
