Sedum plants have been prized for generations and will grow in poor soil and with minimal water or care. These low-growing succulents frequently adorn rock gardens, where they will grow in crevices and rocky soil where you wouldn't dare try another plant. Although normally used outdoors, sedums also make beautiful and low-maintenance houseplants.
Sedums like to be ignored, making them a good choice for the beginning houseplant collector or occasionally negligent enthusiast alike. They naturally thrive on poor soil and, as succulent plants, store water in their fleshy leaves and don't require frequent watering. You should water your sedum only when you push your finger into the soil and it feels dry. Sedums don't like water around their roots and crown, so choose a potting mixture that drains quickly and thoroughly. Make sure the pot has holes in the bottom to allow water to drain, or add a layer of gravel to keep water from pooling around the roots. Most sedums need full sun, so choose a sunny, south-facing window whenever possible. Sedums love hot weather, so you may want to move your plant outdoors to a porch or patio during the summer. Be sure to bring it back in when cold weather hits, as some species aren't cold-tolerant.
Several cultivars make good houseplants. The "Crenulata" cultivar has rosettes that can reach up to 3 feet in length. The "Cameo" and "Perle von Nurnberg" cultivars have bluish and lavender-coloured leaves, respectively, that add a touch of colour to a houseplant planter. The "Burro Tail" cultivar works well in hanging baskets because of its long, trailing stems.
In the landscape, gardeners frequently use sedum to add colour and texture to rock gardens. Likewise, you can incorporate rocks with interesting colours or shapes into your sedum planter indoors. Ferns and other tall plants add dimension to a planter with a low-growing sedum. When selecting companions for your sedum, make sure you choose plants that also have low water requirements.
Sedums have few problems. Their primary problem comes from gardeners who overwater or overfertilize, which can cause the stems to rot and fall over. If your sedum is toppling over, you might be giving it too much water or fertiliser, or you might need to move it to a container with better-drained soil. Sedums also fall over if they don't receive adequate light.
If you have an outdoor sedum that you love and want to try indoors, you can propagate the plant by breaking off a rosette and putting it in a container of soil. Sedums propagate easily from stem cuttings, and you'll have a new plant rooted in no time.
