Plant Family

Acanthaceae

Nerve Plants, Shrimp Plants & relatives · 2 genera covered

A diverse tropical family represented in indoor cultivation primarily by Fittonia (nerve plants) and Justicia (shrimp plants). The two genera have almost nothing in common in terms of care. Fittonia is a humidity-demanding low-light terrarium plant while Justicia is a bright-light flowering shrub. Read the genus entries rather than assuming a shared care approach.

Fittonia|Nerve Plants
Multiple varieties · Peru & Colombia · Low, creeping
One of the most dramatic fainters in the houseplant world. It collapses completely when dry and recovers within minutes of watering, earning the nickname 'drama plant.' This behaviour is a useful watering indicator rather than a sign of permanent damage, provided it isn't allowed to happen repeatedly. High humidity is the genuine requirement; low humidity causes chronic browning and decline that no amount of watering corrects. Terrarium growing resolves both problems simultaneously.

Description

Low, creeping, mat-forming plant with intricate white or pink vein patterning on dark green leaves. The veining is so dense it gives the leaf surface a mosaic or stained-glass quality. One of the most detailed leaf patterns of any common houseplant. Collapses dramatically when dry and recovers quickly with water. The collapse is useful as a watering signal but repeated wilting reduces the plant's long-term health.

Terrarium growing is where Fittonia excels. The enclosed humidity eliminates its primary care challenge and allows the leaf patterning to develop to its full quality. In open indoor conditions it requires a humidifier nearby or placement in a naturally humid room.

Detailed Care
Humidity60%+ is the non-negotiable requirement. In dry air the leaf edges brown and curl, and the patterning becomes dull. A humidifier or terrarium is the solution.
LightTolerates low light well. Direct sun scorches the thin leaves immediately. A bright but entirely indirect position is ideal.
SoilMoisture-retentive but well-draining. Coir and perlite mix. The surface should not dry out completely.
PropagationStem tip cuttings root easily in moist medium or water. One of the most propagation-friendly plants in cultivation.
Cause of DeathDry air causing chronic decline. Repeated wilting from insufficient watering. Cold drafts.

Description

Pink to deep red vein variants of albivenis. The most vivid forms, including 'Ruby Red', 'Pink Star', and 'Frankie', have an almost luminous quality in good indirect light. More light-hungry than white-veined forms to maintain the intensity of the pink or red coloration, though still unsuited to direct sun. Care is identical to standard albivenis in every other respect.

Description

Compact, smaller-leaved forms. The reduced leaf size makes the vein patterning appear even more intricate relative to the leaf area. Ideal for terrarium use where their small scale fits well alongside other miniature plants. Care is identical to standard albivenis; if anything they are more sensitive to drying out due to the reduced leaf mass.

Justicia|Shrimp Plants & relatives
3 varieties · Tropical Americas · Upright shrub
Grown for the distinctive overlapping bracts that form the shrimp-like flower structure. The actual flowers are the small white or yellow tubes that emerge from between the bracts. Nearly continuous flowering in good light makes Justicia one of the more rewarding indoor flowering shrubs. Requires regular pruning to maintain a compact, bushy shape rather than becoming leggy.

Description

Overlapping copper-pink to brick-red bracts forming pendant clusters that resemble prawns or shrimps. Small white flowers emerge from between the bracts. Flowers continuously in good light. One of the most reliably flowering indoor shrubs. In a bright position it rarely stops producing new flower clusters. Requires regular pinching to stay compact; unpruned plants become leggy within a season.

Detailed Care
LightBright indirect is essential for continuous flowering. In lower light flowering slows or stops entirely.
WaterRegular. Allow top inch to dry between waterings. Reduce in winter if light levels drop significantly.
PruningPinch stem tips regularly to encourage branching. Cut back by one-third after heavy flowering to rejuvenate and maintain compact form.
FertiliserMonthly during active growth. Potassium-forward feed encourages flower production.
PropagationStem tip cuttings root readily in spring and summer.

Description

Small, pendant, tubular flowers in scarlet and yellow. The two-tone combination is the distinguishing feature from brandegeana. More compact growth habit than the shrimp plant. Flowers most heavily in winter and autumn, making it useful for seasonal indoor colour when most flowering plants are dormant. Requires the same bright indirect light and regular pruning as brandegeana.

Aphelandra|Zebra Plant
1 variety · Brazil · Upright flowering shrub
Aphelandra is grown for bold white-veined foliage and showy bracted flower spikes. Non-toxic to cats and dogs per the ASPCA, though it has a reputation for being fussier about watering consistency than most Acanthaceae here.

Description

Glossy, dark green leaves marked with bold white or pale-yellow veining, native to Brazilian rainforest. Produces a striking yellow-orange bracted flower spike when mature, but the plant often declines within a year or two after flowering, which is part of why it's less commonly stocked than its striking appearance would suggest. Watering consistency is the plant's real weak point — it wants soil kept reliably moist, and both under- and over-watering show up quickly as shriveling, yellowing, or dropped leaves.

Detailed Care
WateringKeep the top third of soil consistently moist; allow slightly more drying in winter. Both extremes — bone dry or waterlogged — cause visible stress quickly.
HumidityPrefers higher humidity than typical room air; dry air contributes to lower leaf drop.
After floweringOften declines a year or two after blooming — this is typical for the species rather than a care failure, though good conditions can extend its life.
Cause of DeathInconsistent watering, in either direction, is the most common issue reported for this species.

Description

Small, pointed leaves speckled with pink, red, or white markings against green, native to Madagascar. Bred into many colour variants, all sharing the same care requirements. Grows quickly but tends to get leggy and sparse without regular pinching back, and light strongly affects colour intensity — too little light and the markings fade toward plain green.

Detailed Care
WateringKeep the soil consistently moist; dislikes drying out fully and will wilt noticeably (though usually recovers) if left too dry.
Pinching backRegularly pinch growing tips to keep the plant bushy — left alone it stretches and becomes sparse and leggy within a season.
ColourSpeckled colouring is most vivid in bright indirect light; low light causes the markings to fade toward solid green.
Cause of DeathLetting the soil dry out repeatedly, and/or neglecting to pinch it back, leading to a bare, leggy plant that's hard to recover.
