鐵角蕨屬多年生草本，原種不詳，本種具有葉片短且葉先異常分化的園藝品種。附生性蕨類植物。根纖細密集呈海綿狀，帶狀葉片螺旋狀排列，植株直徑20~60cm。葉長15~30cm、寬5~8cm，末端魚尾狀分裂，葉色淺綠有光澤。

A perennial herb in the genus Asplenium. Parent species unknown. This variety bears short fronds and abnormally differentiated frond tips. An epiphytic fern. Roots slender, dense and spongy-like. Plant sized 20-60cm in diameter. Fronds strap-like, arranged spirally, 15~30cm long and 5~8cm wide. The frond tips split and form a shape of fish tail. Blade light green and shiny.

半日照溫暖環境，全日照栽培需經過光線強度的馴化。栽培介質使用培養土或用水苔包裹根系後附著於樹幹、牆垣上附生栽培。不耐旱，介質略乾就澆水。兩周施用一次液體觀葉植物用速效肥料，稀釋倍數比標示更稀薄，以免造成肥傷。因為是變異種，因此以組織培養法繁殖。

The plant prefers warm and partial-sun environments and needs to be acclimated to prevent sunburn if cultivated in full-sun positions. Use culture soil or sphagnum moss to wrap the roots and attach it to trunks or walls for epiphytic cultivation. Not drought-tolerant, water once the soil slightly dries. Apply quick-release liquid fertilizers specialized for foliage plants once every two weeks, dilute the fertilizer thinner than the instructed ration, so as to avoid fertilizer burn. Being a variety, it has to be propagated by tissue culture method.

與一般植株直徑超過1m以上的山蘇相較下，本種型態特異且植株緊緻矮小，適合都市居家環境種植，生長旺盛的植株與萵苣的造型相似，在觀賞上饒富趣味。使用素雅的盆器單株種植，或與其他觀葉植物、蕨類植物設計為組合盆栽可做為焦點植物，在生態缸造景中也能吸引目光。

Compared with the common Bird’s-nest fern over 1m in diameter, this species is relatively compact, short and unique in shape, which makes it a great urban houseplant. Some vigorous individuals resemble lettuce which adds more fun to watch. It’s a great houseplant planted in a simple and elegant container as a single planter, or as a focal plant mingled with other foliage plants and ferns displayed as a combined potted planter; the plantation in an ecological tank can also attract people’s attention.
