Adiantum hispidulum 'Bronze'

Rough Maidenhair Care & Identification Guide

The magnificent Rough Maidenhair (Adiantum hispidulum var.) is a highly unique and resilient variety, characterized by its coarse, slightly leathery leaflets and distinctively rough, hairy stalks. Originating from rocky forest floors and shaded ravines, this hardy maidenhair features a stiffer, more upright growth habit than its delicate cousins. Because of its rough epidermal texture, it exhibits superior resistance to minor dry spells and lower humidity, making it an excellent 'entry-level' maidenhair fern for indoor enthusiasts. It requires bright indirect light, sandy-peaty soil, and regular watering.

11-Step Professional Care Guide

💧 【Watering & Moisture】 Water when the top 0.5 inches of soil feels dry. While more drought-tolerant than other maidenhairs, keep soil consistently damp.

☀️ 【Sunlight & Exposure】 Thrives in bright, filtered indirect light to partial shade. Protect completely from harsh direct midday afternoon sun.

🪴 【Ideal Soil Mix】 Requires a gritty, free-draining peaty mix. Combine 50% peat moss, 25% perlite, and 25% coarse sand or fine gravel.

🌡️ 【Temperature & Ventilation】 Ideal range is 15°C to 24°C (59°F - 75°F). Slightly more tolerant of dry indoor drafts than delicate maidenhairs.

✂️ 【Pruning & Grooming】 Trim old, dry, or shriveled rough fronds at the base to encourage fresh upright shoots. Clean leaves with a soft brush.

🧪 【Fertilization】 Apply a diluted organic liquid fertilizer once every 6-8 weeks during spring and summer. Do not feed in winter.

🏺 【Potting & Container】 Terracotta pots with drainage holes are highly suitable, wicking away excess moisture to protect the tough root system.

🌱 【Propagation】 Propagated by root division in spring. Carefully slice the short, woody rhizome clumps and plant in fresh, gritty soil.

🐛 【Common Pests】 Scale insects can occasionally settle along the rough, hairy midribs. Remove manually with insecticidal soap.

🦠 【Common Diseases】 Low risk of disease, but root rot can occur if soil is heavy and waterlogged. Flawless drainage is key.

🎓 【Botanist Advice】 The Rough Maidenhair is the perfect choice if you love the maidenhair look but struggle with low indoor humidity. Its rough leaf texture makes it highly forgiving!
