Care at a glance
Light
Resurrection Spike Moss is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Prefers bright indirect light, ideally a few hours of filtered morning sun. Tolerates moderate shade but best greening and recovery speed after drought occurs in brighter conditions. Avoid harsh direct afternoon sun which can bleach the foliage. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.
Watering
Water resurrection spike moss can be kept moist year-round or allowed to dry fully and rehydrated on demand. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. This plant is notable for its desiccation tolerance. For continuous lush growth, keep the substrate lightly moist. Alternatively, allow it to dry and curl, then rehydrate by immersing in water for 30-60 minutes to see the dramatic resurrection response.
Soil and pot
Resurrection Spike Moss grows best in gritty, free-draining mix with some organic matter. Use a mix of sand or fine grit, coco coir, and a little loam. The plant is adapted to rocky, shallow soils and tolerates lean conditions. Avoid heavy, moisture-retentive mixes unless you plan to keep it consistently moist. pH 5.5-7.0. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.
Humidity and temperature
Resurrection Spike Moss sits happiest at around 40-70% humidity and 5-28°C (41-82°F). More humidity-tolerant and flexible than Selaginella kraussiana. At higher humidity it stays permanently green and active. At lower humidity it enters its dormant curled state. Standard indoor humidity (40-60%) is generally fine. If you keep the room above 5 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.
Fertilising
Feed resurrection spike moss sparingly. Feed lightly with a dilute balanced fertiliser at quarter strength once a month during active growth in spring and summer. When the plant is in its curled dormant state, withhold fertiliser entirely. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.
Common problems
Below are the issues we see most often on resurrection spike moss in the Growli community. Each is annotated with the most common cause so you know where to start.
- Plant stays permanently curled — Permanently dry conditions prevent the plant from opening. Rehydrate thoroughly and maintain at least moderate humidity.
- Rot after prolonged wet conditions — Extended waterlogging can cause the crown to rot. Ensure good drainage and avoid keeping the plant wet for weeks at a time.
- Pale, washed-out foliage — Too much direct sun. Move to a position with bright but filtered light.
- Fungus gnats — Common in moist indoor conditions. Allow the surface to dry slightly and use sticky traps.
- No resurrection response — Very old or stressed plants may take several hours to rehydrate fully. Ensure complete immersion in room-temperature water rather than surface watering.
Companion plants
Resurrection Spike Moss pairs well with Cheilanthes viridis, Haworthia fasciata, Gasteria gracilis, and Echeveria setosa. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.
Propagation
Separate offsets from the outer edge of the rosette with a clean knife, ensuring a few roots are attached. Pot in a gritty mix and keep lightly moist until established. Can also be propagated from stem cuttings pressed into moist compost. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.
Toxicity to pets
Resurrection Spike Moss is pet-safe. Not individually listed by the ASPCA. Selaginella species are broadly considered non-toxic to cats and dogs and do not belong to any recognised toxic plant family. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).
Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
Resurrection Spike Moss care — frequently asked questions
What is the common name for Selaginella tamariscina?
Selaginella tamariscina is most commonly called Resurrection Spike Moss, but it is also known as Tamarisk Spike Moss, Resurrection Plant. The names refer to the same species, so care instructions for Resurrection Spike Moss apply identically to anything sold as Tamarisk Spike Moss.
How much light does resurrection spike moss need?
Resurrection Spike Moss grows best in bright indirect light (just back from a sunny window). Prefers bright indirect light, ideally a few hours of filtered morning sun. Tolerates moderate shade but best greening and recovery speed after drought occurs in brighter conditions. Avoid harsh direct afternoon sun which can bleach the foliage.
How often should I water resurrection spike moss?
Water resurrection spike moss can be kept moist year-round or allowed to dry fully and rehydrated on demand. This plant is notable for its desiccation tolerance. For continuous lush growth, keep the substrate lightly moist. Alternatively, allow it to dry and curl, then rehydrate by immersing in water for 30-60 minutes to see the dramatic resurrection response. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is resurrection spike moss toxic to cats and dogs?
Resurrection Spike Moss is pet-safe. Not individually listed by the ASPCA. Selaginella species are broadly considered non-toxic to cats and dogs and do not belong to any recognised toxic plant family.
What USDA hardiness zone does resurrection spike moss grow in?
Resurrection Spike Moss is rated for USDA zone 6-10 and RHS hardiness H4. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
