|---|---|
| Section class | III-7 (Medium) |
Overview
Registered in 2005, *Hosta* 'Tom Gannon' is a medium-sized cultivar of unknown breeder, derived from a cross between *Hosta* 'Christmas Tree' (pod parent) and an unnamed seedling (pollen parent). It is visually distinctive for its medium green leaves with pale yellow, slightly rippled margins that exhibit sharp, clean, and consistent streaking, combined with rosette flower buds at the top of the scape.
In the Garden
'Tom Gannon' forms an upright, moderate-growing clump reaching 14 inches (35.6 cm) in height and 30 inches (76.2 cm) in diameter. It is suitable for partial to dappled shade in typical hosta-growing zones, where its ovate, lightly wavy leaves with a slightly shiny upper surface and rounded base provide textural contrast. This cultivar pairs well with ferns, heucheras, and other shade-tolerant perennials, and its medium size makes it appropriate for mid-border positions or as a specimen in shaded beds.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. While slugs and deer may damage foliage, the slightly shiny leaf surface offers moderate resistance; monitor and manage as needed in the garden.
