Through evolution, each leaf on the string of pearls (or string of beads plant), Senecio rowleyanus, is almost perfectly spherical. They function as water storage organs and have a smaller surface area to volume ratio than 'normal' leaves, so lose less water. Grow in hanging containers to make the most of the the beads.

Cristate cacti

Mammillaria cristate form — Cristate mammillaria

There are lots of cacti that display crested or cristate growth forms. It's a form of fasciation, which for some plants can have some unsightly results, but in many cacti leads to a beautiful, undulating effect like this Mammillaria geminispina variation (pictured).

Air plants

Air plants, including (Tillandsia) are some of the easiest but most unusual plants you can grow. They're epiphytes, which means they don't require soil to grow – instead they live attached to other plants. Species include Spanish moss (Tillandsia usneoides) that are iconic in the deep south of the United States, draping the branches of great oak trees.

Crassula 'Buddha's Temple'

Crassula 'Buddha's Temple' is a hybrid of Crassula falcata and Crassula pyramidalis. This slow-growing variety will look good for years. Grow it in a bright, airy spot in cactus compost.

Fishbone cactus

The fishbone cactus, Epiphyllum anguliger, has distinctive zig zag leaves. As an epiphyte it looks great in a hanging container, which mimics its natural environment. A bright spot out of hot sun is best, though it'll benefit from extra sunlight towards the end of summer to aid the production of the stunning, fragrant flowers.

Crassula 'Hottentot'

Crassula 'Hottentot' is a fantastic hybrid, with small, succulent leaves that lie close to the stem, giving them a stacked appearance. It's a great trailing house plant and will also produce clusters of small creamy flowers.

Haworthiopsis attenuata

Haworthiopsis are a group of generally small, succulent plants, many of which possess white, striated tubercles on their leaf surfaces. Haworthiopsis attenuata (shown left and back) is one such species – it's easy to grow expanding fairly quickly by producing offsets and enjoys growing in bright, indirect sunlight.

Staghorn fern

As the name suggests, the staghorn fern, Platycerium bifurcatum, has large, branching fronds. They're epiphytes, so don't require soil and can be secured to wooden boards. They'll happily grow in soil, too, and look lovely in hanging containers.
