Selaginella kraussiana spreads so quickly across moist soil that gardeners often mistake its feathery mats for moss. This low-growing plant, native to southern Africa, is a creeping evergreen that thrives in shade and humidity. Its common names include Krauss’s spikemoss, trailing spike moss, and African club moss.
Unlike true mosses, selaginella kraussiana has roots, stems, and leaves, making it a vascular plant. It belongs to an ancient family of plants that have survived for over 300 million years. For gardeners, this means a tough, adaptable ground cover that can handle foot traffic and dense shade.
This plant is not just for outdoor landscapes. It also works beautifully in terrariums, fairy gardens, and as a potted houseplant. Its bright green, fern-like foliage creates a lush, carpet-like effect wherever it grows.
Why Choose Selaginella Kraussiana
You might wonder why this plant deserves a spot in your garden or home. The answer is simple: it delivers texture and color in places where other plants struggle. Deep shade under trees, north-facing walls, and damp corners are all prime real estate for this spikemoss.
It grows fast, which is a double-edged sword. On one hand, you get quick coverage for bare soil. On the other hand, it can become invasive if left unchecked. Knowing how to manage its growth is key to enjoying this plant without regret.
Key Benefits Of This Ground Cover
- Thrives in low light conditions where grass won’t grow
- Creates a dense, soft mat that suppresses weeds
- Requires consistent moisture but tolerates brief dry spells
- Works well in containers, hanging baskets, and vertical gardens
- Adds a prehistoric, woodland feel to any landscape
Another benefit is its versatility. You can use it as a filler between stepping stones, as a border plant, or as a living mulch around taller plants. It also pairs well with ferns, hostas, and other shade-loving perennials.
Ideal Growing Conditions
Getting the conditions right is not difficult, but you must pay attention to moisture and light. This plant is not a fan of hot afternoon sun. It prefers filtered light, dappled shade, or even full shade in most climates.
Morning sun is acceptable, but harsh midday rays will scorch the leaves. If you grow it indoors, place it near a north or east-facing window. Artificial grow lights also work well, especially in rooms with low natural light.
Soil Requirements
Selaginella kraussiana likes rich, organic soil that holds moisture but drains well. Pure garden soil is often too heavy and compacted. A mix of peat moss, perlite, and potting soil works perfectly for containers.
For outdoor planting, amend the soil with compost before planting. This improves both drainage and water retention. The ideal soil pH is slightly acidic to neutral, around 5.5 to 7.0.
Watering Needs
Consistent moisture is non-negotiable. The soil should never dry out completely, but it should not be waterlogged either. Water when the top inch of soil feels dry to the touch. In hot weather, you may need to water daily.
Indoor plants need less water, especially during winter. Reduce watering when growth slows down. Always use room-temperature water to avoid shocking the roots.
How To Plant Selaginella Kraussiana
Planting this spikemoss is straightforward. You can start with small nursery pots or divide an existing clump. Here is a step-by-step guide to get you going.
- Choose a location with partial to full shade and good air circulation.
- Prepare the soil by loosening it to a depth of 6 inches and mixing in compost.
- Dig a hole slightly larger than the root ball of your plant.
- Place the plant in the hole and backfill with soil, pressing gently.
- Water thoroughly after planting to settle the soil around the roots.
- Add a layer of mulch to retain moisture and keep the roots cool.
Space multiple plants about 12 inches apart. They will fill in quickly, creating a solid carpet within a few months. For faster coverage, you can plant closer together, but you will need to divide them sooner.
Selaginella Kraussiana Care Guide
Once established, this plant requires minimal maintenance. The main tasks are watering, occasional feeding, and controlling its spread. Here is what you need to know.
Fertilizing
Feed your spikemoss with a balanced, water-soluble fertilizer once a month during the growing season. Use a half-strength solution to avoid burning the delicate roots. In winter, stop fertilizing entirely.
Organic options like fish emulsion or seaweed extract work well. They provide gentle nutrients without the risk of chemical buildup in the soil.
Pruning And Trimming
Pruning is not strictly necessary, but it helps maintain a tidy appearance. Use sharp scissors to trim back any leggy or overgrown stems. You can also shear the entire plant lightly to encourage denser growth.
If the plant spreads into areas where you don’t want it, simply pull up the runners. They root easily, so you can transplant them elsewhere or discard them.
Winter Care
In USDA zones 8 through 10, this plant is evergreen and can stay outdoors year-round. In colder zones, it will die back in winter but may return from the roots if mulched heavily. Alternatively, grow it in containers and move them indoors.
Indoor plants need less water and no fertilizer during winter. Keep them away from drafts and heating vents, which can dry out the air and damage the foliage.
Propagation Methods
Propagating selaginella kraussiana is easy and rewarding. You can multiply your plants for free using one of these methods.
Division
Division is the simplest method. Carefully dig up a clump of the plant and separate it into smaller sections. Each section should have some roots and several stems. Replant immediately in moist soil.
This method works best in spring or early summer when the plant is actively growing. Water the new divisions well and keep them shaded for a few days to reduce transplant shock.
Stem Cuttings
Stem cuttings also root quickly. Take a 3-4 inch cutting from a healthy stem, remove the lower leaves, and place it in water or moist potting mix. Roots will appear within 1-2 weeks.
Once the roots are about an inch long, transplant the cutting into soil. Keep it in a humid environment until it establishes. A plastic bag over the pot creates a mini greenhouse effect.
Common Problems And Solutions
Even with good care, you might encounter a few issues. Here are the most common problems and how to fix them.
Yellowing Leaves
Yellow leaves usually indicate too much water or poor drainage. Check the soil moisture and ensure the pot has drainage holes. If the soil is soggy, repot the plant in a well-draining mix.
Yellowing can also result from too much direct sunlight. Move the plant to a shadier spot and see if the color improves.
Brown, Crispy Tips
Brown tips are a sign of low humidity or underwatering. Increase the humidity around the plant by misting it daily or placing a humidifier nearby. Water more frequently, especially during hot, dry periods.
Indoor plants often suffer from dry air in winter. Grouping plants together or placing a tray of water nearby can help raise humidity levels.
Pests
Spider mites and aphids are the most common pests. They thrive in dry conditions, so keeping the plant well-watered reduces the risk. If you spot pests, wash them off with a strong stream of water or use insecticidal soap.
Check the undersides of leaves regularly for signs of infestation. Early detection makes treatment much easier.
Landscaping Ideas With This Spikemoss
This versatile plant fits into many garden styles. Here are some creative ways to use it in your landscape.
- Create a living pathway by planting it between stepping stones
- Use it as a ground cover under shade trees
- Plant it in rock gardens for a soft, contrasting texture
- Add it to container arrangements as a trailing filler
- Line a shaded border with it for a uniform, manicured look
It also works well in Japanese-style gardens, where its fine texture mimics moss. Pair it with stones, water features, and bamboo for an authentic aesthetic.
Indoor Growing Tips
Growing selaginella kraussiana indoors is a great option for apartments and offices. It does well in terrariums, which provide the high humidity it craves. Here are some tips for indoor success.
Choosing The Right Container
Use a shallow pot or dish garden with good drainage. Terrariums with a lid are ideal because they trap moisture and create a self-sustaining environment. If using an open pot, place it on a pebble tray filled with water.
Light Requirements Indoors
Bright, indirect light is best. A north-facing window is perfect. If you only have south-facing windows, place the plant a few feet away from the glass or use a sheer curtain to filter the light.
Fluorescent or LED grow lights also work well. Keep them on for 12-14 hours a day to simulate natural daylight.
