This is not related at all to Selaginella uncinata, but it is just a trade name. This plant species is rare in the hobby, and comes from Southeast Asia.

Very low-growing, to the point where it is essentially flat against the growing media. Grows sparse, as opposed to dense/clumping.

I've had it produce both blue-iridescent as well as red foliage, depending on the growing conditions (lighting, temperature, nutrients)

✅Similarly sized, but non-exact cutting for sale.
