A Misty Masterpiece of Speckled Sophistication
Hosta 'Allegan Fog' is an extraordinary medium-sized cultivar that brings a unique, ethereal texture to the Canadian shade garden. Discovered as a sport of 'Fortunei Aurea' and registered by Ken Herrema in 2000, this variety is celebrated for its rare "misty" variegation pattern. The leaves feature a crisp, dark green margin that surrounds a parchment-white centre—but look closer, and you'll see the centre is heavily speckled and "fogged" with fine green dots. This intricate detailing creates a hazy, multidimensional effect that appears to shift as you move through the garden, making it a premier conversation piece for any collector.
Why It Stands Out
-
Unique Speckled Variegation: The parchment centre is uniquely "misty," filled with delicate green flecking that gives the plant its namesake "foggy" appearance.
-
Wavy, Twisted Foliage: Heart-shaped leaves feature a distinct twist and a ruffled margin, adding a sense of swirling motion to the mound.
-
High-Contrast Borders: The dark green margins provide a sharp, clean frame that makes the lighter centre truly pop in shaded corners.
-
Upright to Mounding Habit: Forms a dense, tidy clump (approx. 45 cm tall) that works beautifully as a front-of-the-border specimen.
-
Lavender Summer Interest: Produces elegant lavender flowers on 60 cm scapes in midsummer, perfectly complementing the cool-toned foliage.

Grower's Tip
To maintain the "misty" contrast of 'Allegan Fog,' we recommend a spot with dappled morning light; too much deep shade can cause the speckled centre to turn a more solid green over time. This variety is a reliable grower in our Quebec climate and is known for holding its variegation well into the late summer. At our nursery in Bécancour, QC, we meticulously monitor each division to ensure the signature "fogging" and twisted leaf shape are fully present before shipping. This True to Type verification is our guarantee that you are receiving the authentic Herrema selection, ready to bring a touch of misty elegance to your landscape.
