Bottle gardens come in many shapes and sizes; glass sweet jars, jugs, wide-mouthed mason jars and old fish bowls all make serviceable terrariums. The only true consideration with terrariums is plant choice. The plants you choose dictate how you plant them, where you place the terrarium and the amount of care your bottle garden needs.
Though this plant is classified as a tree, it grows little taller than 15 cm (6 inches). Jade plants feature bright green oval leaves, thick with holding moisture. They bloom with dusky lavender flowers and have elegant, angular trunks and branches. These succulents require very little maintenance. They love hot, bright, dry conditions. This makes them perfect for sunny windowsills and forgetful gardeners. Make sure this plant has bright full or indirect sunlight for most of the day.
Bird's Nest Sansevieria
Bird's Nest Sansevieria features long, pointed, vertically-growing leaves. The leaves have horizontal, striated stripes that vary from dark green to pale green and even white. They look something like seaweed and provide an attractive backdrop to shorter, more colourful plants. Recommended as houseplants, Bird's Nests need little care. They like full sun and moist, well-drained soil. Sand in your terrarium and a sunny windowsill care for these needs perfectly.
This low-spreading evergreen looks like a small fern. Its leaves have small, oval fronds sprouting from dark stems that grow no longer than about 7.5 cm (3 inches). In nature, it grows from between cracks and crevices in limestone and other rocks. It likes moist conditions and remains green all year round. It thrives if planted in moist, well-drained soiled mixed with a little peat moss. It also likes bright, indirect light (to mimic forest conditions). Plant Maidenhair around the edges of your terrarium to act as a foreground for taller plants near the centre of the bottle.
