Pellionia repens / Procris repens
Pellionia repens (recently reclassified to Procris repens) is a gorgeous and super easy to grow terrarium plant. It’s often called the “Trailing Watermelon Begonia” despite not being a begonia at all (or a watermelon for that matter) for it’s begonia like asymmetrical leaf growth and deep watermelon rind colours. Native to Southeast Asia, it has found a home as a houseplant thanks to its lush foliage and deep green, red and purple colours. It’ll grow under most household conditions, but it really thrives in a warm and humid terrarium. If you’re looking for an easy vine to fill out your terrarium, you can’t go wrong with this one.
