A Reptilian Masterpiece for the Shade Border
Hosta 'Alligator Rock' is a striking cultivar from prolific hybridizer Don Rawson, bred to bring intense tactile interest to the shady landscape. He named it for its extraordinary leaf texture, which mimics the rugged, scaly hide of an alligator. The thick, leathery leaves are densely covered in symmetrical rows of bumps and puckers that deepen with maturity. It performs reliably across Canadian hardiness zones 3 through 9. Plant it as a bold structural specimen where texture and presence do the talking.
-
Corrugation: Thick, leathery leaves covered in symmetrical rows of bumps — one of the most rugged textures in the genus, intensifying as the clump matures.
-
Colour: Emerges with a soft blue-green glaucous bloom in spring, maturing to a rich, saturated deep green that holds all season.
-
Slug Resistance: Exceptionally thick leaf substance naturally deters common garden pests, keeping foliage pristine through the season.
-
Flowers: Near-white blooms on elegant spikes in mid-summer, rising above the dark canopy for a striking contrast.
-
Size: 35–45 cm (14–18") tall × 60 cm (24") wide — a tidy, compact mound well-suited to borders and containers.

Grower's Tip: 'Alligator Rock' handles Canadian winters with ease from Zone 3 through 9, and the heavy corrugation becomes even more dramatic with each passing season. At our nursery in Bécancour, QC, we wait for the characteristic rows of bumps to clearly manifest on the emerging spring foliage before shipping. Our True to Type standard means you receive the authentic Don Rawson selection.
