Don’t be fooled by a plant’s size. Ajugas may be little, but they are strong and hardy groundcovers. They can help with erosion control on a bank or slope, fill in a patchy lawn where grass won’t grow, or simply offer color to shaded areas. They’re also excellent for planting beneath bushes and trees.
Ajugas are very attractive because their leaf color and attractiveness last virtually all year, and they produce blue, purple, or white blooms from spring to summer. Ajuga reptans, sometimes known as carpetweed or bugleweed, is a perennial that thrives in zones 3 to 9.
The lustrous leaves of these evergreen shrubs form dense mats. They can tolerate full sun to partial shade, but full sun brings out the greatest color in the leaf. Ajugas are easy to cultivate in practically any type of soil and prefer a moist, well-draining environment, but they can endure dryness for short periods of time.
Because ajuga spreads through stolons, or horizontal stems that creep along the ground, it’s important to consider where you plant it. This mint family member spreads quickly and can become invasive. Planting too close to flower beds, lawns, or other areas where you’ll have to remove it frequently is a bad idea. If you’re worried that ajuga is an invasive plant in your area, check out the Invasive Plant Atlas.
Plant ajugas when all dangers of frost have passed. Then, spacing the holes 8 to 15 inches apart, dig holes just deep enough for the root balls. Gently loosen the roots of the plants, then plant them and firm the dirt around them. To settle them in and eliminate air pockets, water them thoroughly. Fertilizing ajugas is rarely necessary.
To keep your ajugas from becoming overloaded, you should thin them every three years or so. If desired, divide and replant established clumps in the fall or early spring.
Crown rot is an issue, particularly in hot, humid climates or in heavy soils. It’s easy to notice since the lower leaves have rot and spots on the tops of the plants. Give your plants plenty of air circulation and avoid overfertilizing to avoid this illness. Crown rot has no treatment, therefore if it appears, you’ll have to uproot and destroy the damaged plants. When it’s time to replant, consider a new type of groundcover to reduce the chances of the problem reappearing.
Patches of ajuga will occasionally die. If this occurs, remove the dead leaves but leave the roots in place. In most cases, the plants will return the next year.
Ajugas are low-maintenance plants with good rabbit and deer resistance. They don’t need to be pruned, but if you want them to look a little neater after the blooms fade, mow them using a high setting on your mower.
Try coral bells, hostas, ferns, daffodils, astilbe, forget-me-not, violas, hardy geraniums, and other woodland species if your ajugas are in the shadow.
Sweet Woodruff
With clusters of fragrant white blooms that appear at the start of each summer, this multipurpose plant spreads swiftly to form a dense cover roughly 15 inches high. The star-shaped flowers and vivid green leaves endure long into the fall months.
Bunchberry
Bunchberry is a dogwood-like plant with emerald green foliage, huge white flowers, and clusters of brilliant red berries. It grows to a height of six to eight inches, spreads rapidly, and thrives in cool, summer shade, liking acidic soil.
Goldenstar
This stunning favorite among gardeners has bright yellow blossoms and rich green leaves. Flowers bloom in the spring and late summer, and the plant grows to be four to six inches tall. Goldenstar is resilient in both northern and southern regions, and it thrives in either part or full sun.
Trailing Periwinkle
This plant forms a dense ground cover with stunning blue, lavender, white, or purple blooms that bloom swiftly. The plant thrives in full to partial shade, and it’s a low-maintenance, pest-free addition to the base of trees or tall shrubs, or at the top of a rock wall.
Does Ajuga prefer sun or shade?
These plants can grow in any generally well-drained soil, and while they tolerate full sun, they develop more quickly in partial shade. Plant these perennials 6 to 12 inches apart in the spring or early fall. Remove old flower spikes by mowing or trimming them.
How quickly does Ajuga spread?
Ajuga will try to conquer the entire region in its immediate proximity. Although it is an aggressive spreader, it is relatively easy to contain because it spreads over the ground.
It is recommended that you use a shovel or a spade to edge the borders of the territory limit assigned to Ajuga twice a year, once in the spring and once in the middle of summer.
There is no need to be concerned because this plant does not spread quickly; rather, it spreads slowly and steadily.
You should not plant this next to a lawn because grass cannot compete with it and will quickly become overrun, leaving you with an Ajuga lawn rather than a grass lawn.
Is Ajuga a good ground cover?
Ajuga is an ubiquitous groundcover, but this dark, coppery-burgundy variety works well with darker plants with spiky foliage, such as black mondo grass. Don’t be fooled by a plant’s size. Ajugas may be little, but they are strong and hardy groundcovers. The lustrous leaves of these evergreen shrubs form dense mats.
What ground covers shade?
For shade, there are a number of excellent ground coverings. Here are some popular recommendations to think about.
Hosta – Hostas are one of the most popular shade ground coverings. Hosta plants are a superb shade ground cover that can tolerate shade if the soil is well-drained. They’re attractive in foundation gardens, but they’re also attractive when strategically put around trees.
Periwinkle – You can plant periwinkle if you have a hilly area with some trees, such as on the bank between your yard and your neighbor’s. Periwinkle is a robust shade ground cover with beautiful light blue or lilac-colored blooms. Periwinkle, on the other hand, should be avoided because it has a tendency to quickly take over the space it is in.
Pachysandra – Pachysandra is another attractive shade ground cover. Pachysandra is a plant that grows up to a foot (0.5 m) tall and has huge, dark green leaves. These are ideal for use as a filler in foundation gardens with bigger plants. Pachysandra is an excellent ground cover for shade since it may cover the ground beneath the shrubs and prevent weeds and other undesirables from developing, giving your foundation garden a tidy appearance.
What plants need shade survive?
Ferns are among the world’s oldest living plants, reaching back to the dinosaur era. These dependable perennials are planted for their gorgeous fronds that contribute texture and form to the landscape, making them a must-have addition to any forest or shade garden. There are dozens of garden-worthy species that can withstand a wide range of environmental conditions. Most demand rich soil and plenty of water, although others, like Western sword fern (Polystichum munitum), are drought-tolerant once established, making them a suitable choice for difficult locations like dry shadow. Primrose (Primula), bishop’s hat (Epimedium), hosta (Hosta), masterwort (Astrantia), and wood sorrel are just a few of the woodland shade plants that go nicely with ferns (Oxalis).
Plants to Try:
Ostrich fern (Matteuccia struthiopteris), cinnamon fern (Osmundastrum cinnamomeum), maidenhair fern (Athyrium niponicum var. pictum), Japanese painted fern (Athyrium niponicum var. pictum), maidenhair fern (Athyrium niponicum var. pictum), maidenhair fern (Athyrium n (Adiantum pedatum).
Does bugleweed grow in shade?
Bugleweed grows best in a rich, wet, well-drained soil, but will withstand clay and poor soils. Plant in full sun to create a shady environment. If you’re going to plant bugleweed near to a grass area, bear in mind that it has creeping tendencies; use edging to keep it from spreading. Run a lawnmower over spent flowers to deadhead them. Seed, cuttings, or division are all methods of propagation. To avoid crowding, division can be done at any time of year and should be done every two to three years. There are no major pest or disease problems; nevertheless, crown rot can occur in hot, humid conditions or in locations with inadequate air circulation.
Will ajuga choke out other plants?
There’s no doubting that Bishop’s Weed in variegated form is a lovely plant. It thrives in shady areas where splotches of white are needed to liven things up. But you’ll never be able to enjoy just a smidgeon of Bishop’s Weed. Its roots form a dense mat as it grows, suffocating any neighboring vegetation. While this may sound like a good way to keep weeds at bay, it will eventually take over your garden plants as well.
Bishop’s Weed was initially labeled as invasive in Rhode Island in 1863, although you can still get it for sale. You may probably determine it’s a member of the carrot family by looking at the white, umbel blossoms, which look a lot like Queen Anne’s Lace. The plant does attract helpful insects, so it has some virtues, but it is simply the incorrect plant for many situations.
If you’ve already planted Bishop’s Weed and regret it, the best way to get rid of it is to use up all of your resources. In the early spring, cut it as short as possible and cover the area with plastic. The plants are unable to photosynthesize, receive insufficient water, and are overheated. They ultimately give up, even if it takes a long time.
Goutweed (a mashup of goat weed—goats will eat it) and Snow on the Mountain are other names for Bishop’s Weed.
