Growing tall sedums for low maintenance is a great choice for busy gardeners. They can thrive in poor soil and require infrequent watering.

Tall sedums are drought-tolerant and can survive with minimal watering. This makes them perfect for areas with low rainfall or for gardeners who tend to forget to water their plants.

One of the key benefits of growing tall sedums is their ability to store water in their leaves. This adaptation allows them to survive long periods of drought.

With proper care, tall sedums can grow up to 3 feet tall.

Growing and Maintenance

Tall sedum grows best in full sun, especially the dark-foliaged cultivars, which will turn darker with more sun.

Well-drained soil is a must, and they're flexible about soil pH, but slightly alkaline soil is even better.

To keep tall sedum happy, a simple annual side-dressing of compost is usually all you need, no need for much fertilizer.

After fall flowering, leave the seedheads until they're no longer ornamental, then cut them back on a dry midwinter's day.

Low-Maintenance Garden Staple

Tall sedums are a low-maintenance garden staple that can thrive in a variety of conditions.

They can be planted in porous, mineral-rich soil with added organic matter for perfect rooting.

Tall sedums prefer drier feet, but they aren't as drought-tolerant as some of the short, spreading Sedum species.

They can withstand really high heat and drought, but still require some care.

All sedums attract bees and butterflies, making them perfect for pollinator gardens.

The succulent-like foliage of tall sedum can be green, chartreuse, variegated, or shades of burgundy, topped with pink, burgundy, white or chartreuse-yellow blooms.

The blooms often age to shades of russet reds and browns, providing pretty interest in all seasons.

With the right care, tall sedums can give you encore performances season after season.

They all do well with the same simple care, making them a great choice for busy gardeners.

Clean Up in Spring

Clean up in spring by cutting back dead tall sedum stems early in the season. This lets you appreciate the new spring growth when it starts.

Cut the stems as short as possible to keep them from competing with new growth for water and nutrients.

If a stem comes off with a few leaves attached, plant or pot it right away and you'll have a new addition to the garden.

Divide in Spring

Spring is the perfect time to divide tall sedum, as it's easier to do without worrying about breaking off stems or leaves.

You can use a shovel to dig around the plant and lift the dense rootball out of the ground.

Split plants with a shovel or soil knife, and cut the rootball into whatever size division suits your needs.

Replant tall sedum divisions at the same depth they were growing before division.

Drought Tolerance and Watering

Tall sedums like Autumn Joy and Dynomite are fairly drought-tolerant, but they'll produce the largest, most floriferous plants with regular watering while they're actively growing.

In very dry conditions, these tall sedums will grow more slowly and may even get spindly.

The best stonecrops for super dry conditions are certain creeping sedums like Sedum tetractinum and Sedum kamshaticum.

Some creeping sedums, like Sedum ternatum, don't tolerate drought, so be careful when selecting one for a dry site.

Tall sedum is so drought-tolerant that you don't have to worry about watering, but too much water can cause them to rot.

In fact, keep organic mulch pulled away from the crown 3 to 4 inches to avoid moisture buildup that causes rot.

Pea gravel and stone mulch are good alternatives to organic mulch.

These plants thrive in sandy to gravelly soils under moderate to low fertility.

Under light shade or in rich organic soils, stonecrops produce weak, floppy shoots.

They decline in wet, soggy soils.

So, if you want to keep your tall sedums happy and healthy, make sure they're in well-drained soil and get plenty of sunlight.

Ideal Growing Conditions

Tall sedums love full sun, with six hours or more of direct sunlight, especially the dark-foliaged cultivars, which will get even darker with more sun.

They're quite flexible when it comes to soil pH, but alkaline soil is a bonus. No need to worry about fertilizing them much, either.

Well-drained soil is essential for tall sedums, and they'll rot in heavy wet soil. This makes them perfect for raised beds, hillside slopes, and containers.

Plant them in porous, mineral-rich soil with added organic matter, like compost, for perfect rooting.

Sun and Pruning

Tall sedums can thrive in full sun, which is essential for their growth and flowering.

Their stems can grow quite tall, but they can be tip pruned in spring to control the height, although this will delay the onset of flowering.

Tall sedums die back to a ground-level rosette in the winter, and many gardeners prefer to leave the dried stems and flowers in place during autumn and early winter as they can be attractive when frost coats them.

The stems will eventually be smashed down by snow or ice, at which point they can be pruned or pulled.

Container and Cut Flower

Tall sedums make excellent cut flowers, perfect for adding a pop of color to your home. Simply cut the stem once most of the florets are open, strip some of the leaves at the bottom, and enjoy.

They also dry well, making them a great choice for arrangements that can be enjoyed year-round.

Tall sedums can thrive in containers, and look great in patio containers.

Containers are a fantastic way to showcase your favorite plants, and sedum is a great choice.

Tall sedums look great in patio containers, adding a pop of color and texture to your outdoor space.

To make the most of your containers, use a decent potting mix that retains water and drains it well.

For a more dramatic effect, combine tall sedums with creeping sedums, which spill over the edges of the pot and create a beautiful display.

Creeping sedums can also be tucked into the nooks and crannies of strawberry pots, pallet gardens, rock walls, and wall gardens, adding a delicate touch to these unique spaces.

They're perfect for hanging baskets too, with their long stems draping down over the edge of the pot.

Cut Flowers

Cut flowers can be a beautiful addition to any room. Tall sedums produce excellent cut flowers.

To enjoy them, cut the stem once most of the florets are open. This will allow you to appreciate their full beauty.

Pollinators and Blooms

Tall sedum is a magnet for beneficial pollinators like bees and butterflies.

Hannah Richardson, a nursery stock grower, has noticed hundreds of little bees crawling among the sedum blooms in her grow house.

The bees are surprisingly quiet in their work, but when you look closer, you'll see at least three or four bees of various species working busily on each plant.

It's a peaceful scene, and if you're quiet and respectful, the bees will continue with their industrious gathering โ€“ and with the faintest contented hum.

People Love the Blooms Too

The unique bloom of tall sedum produces numerous dense, flat clusters of tiny, pale green blooms on top of sturdy, succulent stems.

These blooms remind you a little of broccoli, and as the seasons progress through summer and into the fall, the tiny flowers transition from green to pale pink, then deeper shades of pink and mauve.

You'll notice a definite increase in pollinator activity around tall sedum in late summer when the blooms are fully open.

To prevent flopping, you can stake your tall sedum plants in the spring. This will keep them upright and looking their best.

Cutting back tall sedum stems by up to half can also prevent flopping. This can be done from spring to early summer, and it will produce smaller, more numerous flowers later on.

Cutting back stems at a leaf joint is the best way to encourage new growth. Two new stems will form, and they will flower later in the season.

Cutting back 'Matrona' by a third, as shown in the photo, is a good example of how to do this.
