Overview

Registered in 2011 as a sport of *Hosta* 'Pineapple Upsidedown Cake', 'Lava Flow' is a small-sized cultivar distinguished by its blue-green leaves with gold margins and, most notably, its yellow leaf veins that remain visible for much of the growing season. The leaves are narrowly elliptic with tapered bases, flat margins, and a thick glaucous bloom on the undersides, measuring 8 inches (20.3 cm) long and 3 inches (7.6 cm) wide with 8 to 9 vein pairs.

In the Garden

'Lava Flow' forms a compact, mound-like clump reaching 15 inches (38.1 cm) in height and 34 inches (86.4 cm) in diameter, with a fast growth rate. It performs best in partial to full shade, typical for hostas, and its small size makes it suitable for the front of borders, rock gardens, or container plantings. Companion plants that appreciate similar conditions include ferns, heucheras, and small woodland perennials.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Lava Flow' is susceptible to slug and deer damage, so appropriate management measures may be necessary in areas where these pests are prevalent.
