Tiny, delicate Peperomia Emarginella. Peperomia variety that has long, thin stems and puts out tiny leaves. Great for terrariums of all size: nice and compact for smaller terrariums, but can also be used in larger terrariums for thin foliage. One of the best plants for trailing up and off wood.
Care
As with most Begonias, the Begonia Lita can be picky when it comes to their conditions, especially when their new home is substantially different to what they are used to. However, when settled, they grow very well; the effort is more than worth it!
My begonias are grown in a high-humidity environment and this should be a focus. They generally take very well to terrariums and flourish when they are comfortable.
This plant needs a moist but well-draining soil mix that will retain moisture but allow the excess to drain away.
