Selaginella wildenowii

Selaginella wildenowii is a species native to tropical and subtropical Asia, it is mainly cultivated in tropical greenhouses or terrariums. This species, like almost all Selaginella, has an incredible color palette, ranging from dark blue to turquoise blue or even red in conditions of water stress. This fast-growing species requires high humidity and grows in a lot of substrates. Once well established, it will bring a beautiful touch of blue to your terrarium and can largely fill an entire space. To limit it, you can prune it, making it more compact and all the more beautiful.
