Fun Facts
- 🌱 Painted Japanese Fern gets its 'painted' common name from the striking silvery-gray overlay on fronds combined with burgundy or reddish midribs and petioles, creating the appearance of hand-painted foliage
- 🌱 This fern is one of the few ferns with genuinely colorful foliage; most ferns are simply green, making Athyrium niponicum cultivars like 'Pictum' highly sought after by shade gardeners
- 🌱 Ferns reproduce via microscopic spores released from the undersides of mature fronds rather than seeds; spores can be collected and propagated to create new plants, though division is much easier for home gardeners
