Nephrolepis exaltata 'Vitale'

Species origin and the European cultivar

‘Vitale’ is a cultivar name used in European horticulture for a compact, partly curled form of Nephrolepis exaltata. It belongs to the broad Boston-fern and sword-fern tradition built from selected forms of this variable species.

In the wild, Nephrolepis exaltata ranges across the tropical and subtropical Americas and can root in soil or perch on trunks and palms in moist forest and floodplain communities.

Moisture and airflow for fern care

Curled-frond care: The even curl of healthy foliage is part of the cultivar, so leave green curled tissue intact and remove only fully brown fronds at the base.

Water and soil: Maintain consistent moisture without saturating the middle of the pot. Check more than one point or use pot weight, since the outer mix can feel dry while the central root zone remains wet.

Warmth, humidity and feeding: Steady indoor warmth and humid air favour new fronds, together with protection from cold draughts. Feed at a modest label rate while new fronds are being produced.

Propagation: Divide established plants or separate young plants rooted along creeping runners to retain the cultivar. Spores will not reliably reproduce its curled form.

Troubleshooting this curled fern

• Consistent curled fronds: An even curl repeated across firm green fronds is the defining form of ‘Vitale’. Do not remove or straighten healthy curled tissue merely because it differs from an ordinary Boston fern.
• One scarred, distorted flush: Uneven twisting accompanied by silver scarring or black specks suggests thrips feeding while the frond was folded. Keep the fern apart, inspect the newest growth and treat for thrips only if the silver scarring, black specks and the pest itself are present.
• Longer, open fronds: If successive fronds lose density and become unusually open, insufficient light is plausible. Provide brighter filtered light and judge the response from new growth; existing fronds will not become denser.
• Crisping or wet-root wilt: Crisp leaflets with a light pot support drought. Limp yellow fronds while the centre stays wet support root stress. Check moisture below the surface before adding water to a wilted fern.
• Crown softness: A darkening or soft centre is more serious than an isolated brown outer frond. Keep water out of the crown, remove decayed debris and restore ventilation and root-zone drainage.
• Webbing, bumps or sticky residue: Mites create stippling and fine webbing; scale forms attached bumps and may produce honeydew; mealybugs form cotton. Keep the compact plant separate and inspect between the curled leaflets before treatment.

Nephrolepis exaltata ‘Vitale’ is non-toxic to cats and dogs

• This plant is non-toxic to cats and dogs.
• Its effects on people are unclear, so keep it away from young children who may chew it.
• Eating a large amount can still cause an upset stomach. Seek medical or veterinary advice if symptoms continue.

Nephrolepis exaltata: where the name comes from

Greek nephros, kidney, and lepis, scale, form Nephrolepis and refer to the small kidney-shaped coverings over the spore-bearing patches. Exaltata means elevated or very tall.

Heinrich Wilhelm Schott established the genus Nephrolepis in 1834 in Genera Filicum (Vienna), plate 3.

Carl Linnaeus first described it as Polypodium exaltatum in 1759 in Systema Naturae, tenth edition, volume 2, page 1326. Heinrich Wilhelm Schott later placed it in Nephrolepis as Nephrolepis exaltata in 1834 in Genera Filicum (Vienna), plate 3.
