Overview
Registered in 1994, 'Rosie Posie' is a small hosta cultivar resulting from a cross between *Hosta* 'William Lachman' (pod parent) and *Hosta montana* (pollen parent). It is visually distinctive for its dark green leaves with wide, creamy white, slightly rippled margins and reddish green scapes.
In the Garden
'Rosie Posie' reaches approximately 12.5 inches (31.8 cm) in height and 24 inches (61.0 cm) in diameter, with a semi-upright growth habit. It performs best in partial to full shade, where its variegated foliage retains color without scorching. Its small size makes it suitable for the front of borders, rock gardens, or container plantings, and it pairs well with other small shade perennials such as ferns or heucheras.
Care Notes
Water regularly to maintain consistent moisture, especially during dry periods. Fertilize in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
