About Scot's Maidenhair Spleenwort

Asplenium viride · also called Green Spleenwort, Viride Spleenwort · houseplant

Green spleenwort is a small, hardy alpine fern of cool, limestone rocks and crevices across northern and montane regions. Its tufted fronds have a distinctive bright-green stalk (unlike the black-stemmed maidenhair spleenwort). It is a cool-growing rock fern best suited to a shaded crevice, trough, or alpine pot rather than a warm living room, needing sharp drainage and lime.

Ideal humidity: 50-70%

Watch for — Heat and dryness stress: As a cool alpine it sulks and browns in warm, dry rooms. Keep it cool and humid — a shaded trough, frame, or terrarium suits it far better than a heated living room.
