Dracaena marginata (Madagascan dragon tree) in a 12cm pot

Looking very much like a palm tree in miniature, Dracaena marginata (also known as the Madagascan dragon tree) is an evergreen shrub with a crown of long, sword-shaped, dark green leaves, finely edged with reddish-brown.Holder of the prestigious RHS Award of Garden Merit, so you can be sure that it is a tried and tested winner, Dracaena is an easy-to-grow indoor plant that thrives on little care – a superb choice for those of us new to growing houseplants or want low-maintenance indoor displays.Dragon trees need a bright position, which makes them an ideal candidate for a light windowsill out of direct sunlight and away from artificial heat sources such as radiators. They are slow growing, too, taking about 10 years to get to approximately 150cm (5ft), so won't overtake your home.As well as being super-easy to grow, Dracaena is well known for helping keep the air in your home clean as it filters out pollutants: according to NASA, this plant can remove formaldehyde, xylene and toluene, found in furniture, fireplace smoke and common household products.Supplied as an established plant in a 12cm nursery pot.
