H. ‘Jurassic Park’

Overview

Registered in 2006 as a seedling of two unrecorded parent plants, *Hosta* 'Jurassic Park' is a giant cultivar distinguished by its exceptional dimensions and rapid growth rate. Mature clumps reach 108 inches (274.3 cm) in diameter and 40 inches (101.6 cm) in height, forming a dense, mound-like habit. The leaves are broadly ovate with cordate bases, measuring 17 inches (43.2 cm) long by 15 inches (38.1 cm) wide, and exhibit a blue-green coloration with a heavy glaucous bloom on the upper surface and a dull underside. Each leaf bears 17 pairs of veins and is deeply corrugated (rugose), with dark green, flat margins and substantial substance that resists tearing.

In the Garden

*Hosta* 'Jurassic Park' is best sited in partial to full shade, where its blue-green foliage and pronounced rugosity are most pronounced. The mammoth spread—up to 9 feet (2.7 m) at maturity—requires generous spacing from neighboring plants; it is not suitable for containers. Companion plants should include shade-tolerant perennials with contrasting textures, such as ferns, *Heuchera* (coral bells), or *Astilbe*, which complement the hosta's bold, corrugated leaves without competing for space. The mound-forming habit and fast growth make it an effective groundcover for large woodland gardens or as a specimen in deep shade beds.

Care Notes

Provide consistent moisture during establishment and in dry periods, as the large leaves transpire heavily. Fertilize lightly in early spring with a balanced, slow-release formulation; excessive nitrogen may reduce leaf substance. Slugs and deer may feed on the foliage, though the thick, corrugated leaves offer moderate resistance compared to thinner-leaved cultivars. Hardiness is typical for the genus (USDA zones 3–8), but protection from strong winds is advisable to prevent leaf tattering.
