Selaginella uncinata

What is the plant

Selaginella uncinata, the blue spikemoss, peacock moss, peacock spikemoss, or spring blue spikemoss, is a species of plant in the Selaginellaceae family. It is widely cultivated outdoors along the Gulf Coast and in greenhouses and nurseries.

As brilliantly iridescent as the colors of a peacock are the metallic bluish-green shades on peacock fern (Selaginella uncinata). Also commonly called "rainbow moss," this plant is neither a fern nor a moss, but it earns these descriptive names because of its appearance and growth habits. Other than its common names, you may also find Selaginella uncinata called "spike moss" or "club moss." Peacock fern has a mat-spreading habit with foliage that grows only a few inches high, with a typical spread up to 18 inches.

How to Care for the Plant

Water
Peacock fern is not a drought-tolerant plant. The soil should stay consistently moist, which means you may need to water your plant often during the extreme heat of summer. If you notice that your peacock fern is turning yellow, check to see if the soil is too dry.
Pruning
Rainbow moss doesn’t really need pruning. But you can trim it if you want to slow down spreading.
Fertilizer
When planted on rich, humus- or compost-enriched soil, peacock fern generally receives most of the nutrients it needs. When the warm temperatures in spring prompt new growth, fertilize with a water-soluble fertilizer that’s diluted to half-strength and do a second application in midsummer.

Sunlight
Peacock fern prospers in shady nooks and woodland gardens. It needs direct sun for no more than a couple of hours each day, and it can even flourish in full shade. A partial shade spot that works well is one that receives filtered sunlight through the overhead canopy of trees, providing much more shade than sun.
Soil
For healthy growth, grow peacock fern on soil that’s enriched with humus or other organic matter.
Propagation
It’s easy to propagate through stem cutting or division. Just cut a part of the plant with a stem node and place it in the soil, keeping it mildly moist. It won’t take more than a few weeks until the roots appear.
