12 Of The Worst Flowers To Put In Your Yard And Why!
Gardening is a beloved pastime for many, bringing beauty and tranquility to your home environment. However, not all flowers are created equal when it comes to planting them in your yard.
Some flowers can cause more trouble than they’re worth, either due to their invasive nature, high maintenance needs, or the problems they bring along.
In this blog, we’ll delve into 12 of the worst flowers to put in your yard and explain why they might be best left out of your gardening plans.
1. English Ivy (Hedera helix)
Why It’s a Problem:
English Ivy might look charming and lush, but it’s a notorious invasive species. It spreads rapidly, choking out native plants and climbing up trees and walls, causing damage to structures and ecosystems. Its aggressive growth can be difficult to control once it’s established.
Alternatives:
Consider planting native ground covers such as wild ginger (Asarum canadense) or creeping phlox (Phlox stolonifera), which offer beauty without the invasive tendencies.
2. Morning Glory (Ipomoea spp.)
Why It’s a Problem:
While Morning Glories produce beautiful blooms, they also spread quickly and can become highly invasive. They reseed themselves prolifically and can overrun other plants in your garden.
Alternatives:
For a similarly stunning bloom, try planting clematis. This vine offers vibrant flowers and can be controlled more easily.
3. Japanese Knotweed (Fallopia japonica)
Why It’s a Problem:
Japanese Knotweed is infamous for its destructive nature. Its roots can damage foundations, walls, and pavements. It’s incredibly difficult to eradicate once it’s taken hold, often requiring professional intervention.
Alternatives:
Switch to bamboo-like plants such as the non-invasive clumping bamboo (Fargesia spp.) which provides a similar aesthetic without the damaging effects.
4. Bishop’s Weed (Aegopodium podagraria)
Why It’s a Problem:
Bishop’s Weed is an aggressive ground cover that spreads quickly through rhizomes. It can dominate garden beds, making it nearly impossible to remove completely.
Alternatives:
Opt for plants like the hosta (Hosta spp.) for shady areas or sedum (Sedum spp.) for sunny spots, which are easier to manage and less invasive.
5. Lily of the Valley (Convallaria majalis)
Why It’s a Problem:
Though lovely and fragrant, Lily of the Valley spreads through underground rhizomes and can quickly become invasive. It’s also highly toxic if ingested, posing a risk to pets and children.
Alternatives:
Consider planting the equally fragrant and less invasive sweet woodruff (Galium odoratum) as a ground cover.
6. Purple Loosestrife (Lythrum salicaria)
Why It’s a Problem:
Purple Loosestrife is a major invasive species in wetlands, crowding out native plants and disrupting ecosystems. It spreads rapidly and can be very difficult to remove.
Alternatives:
Try planting native alternatives like blazing star (Liatris spicata) or Joe-Pye weed (Eutrochium purpureum), which support local wildlife and are non-invasive.
7. Wisteria (Wisteria spp.)
Why It’s a Problem:
Wisteria is a beautiful but vigorous climber that can overwhelm structures and trees. Its strong, woody vines can damage fences, trellises, and even buildings.
Alternatives:
Choose less aggressive climbers like trumpet vine (Campsis radicans) or honeysuckle (Lonicera spp.), which provide gorgeous blooms without the structural damage.
8. Mint (Mentha spp.)
Why It’s a Problem:
Mint is notorious for its aggressive spreading via underground runners. It can quickly take over garden beds and lawns, making it hard to control.
Alternatives:
Grow mint in containers to enjoy its benefits without the invasive spread, or opt for less aggressive herbs like basil or oregano.
9. Yellow Flag Iris (Iris pseudacorus)
Why It’s a Problem:
Yellow Flag Iris is an invasive species that spreads rapidly along waterways, outcompeting native plants and disrupting aquatic ecosystems.
Alternatives:
Choose native irises like the blue flag iris (Iris versicolor) for a similar aesthetic without the environmental threat.
10. Creeping Jenny (Lysimachia nummularia)
Why It’s a Problem:
Creeping Jenny spreads quickly and can smother other plants in your garden. It’s difficult to remove once it becomes established.
Alternatives:
Try ground covers like ajuga (Ajuga reptans) or creeping thyme (Thymus serpyllum), which are easier to control and offer lovely blooms.
11. Butterfly Bush (Buddleja davidii)
Why It’s a Problem:
Despite its popularity for attracting butterflies, Butterfly Bush can become invasive and crowd out native plants. It also does not support the full life cycle of butterflies.
Alternatives:
Opt for native flowering shrubs like buttonbush (Cephalanthus occidentalis) or New Jersey tea (Ceanothus americanus) that support local wildlife and are non-invasive.
12. Periwinkle (Vinca minor)
Why It’s a Problem:
Periwinkle spreads aggressively and can outcompete native plants in woodlands and gardens. It’s very difficult to control once established.
Alternatives:
Consider planting native ground covers such as bearberry (Arctostaphylos uva-ursi) or wild strawberry (Fragaria virginiana), which provide similar coverage without the invasive risk.
While the allure of certain flowers is undeniable, it’s essential to consider their impact on your yard and the broader ecosystem. Invasive plants can disrupt local flora and fauna, damage property, and become a significant headache to manage.
By opting for non-invasive, native alternatives, you can enjoy a beautiful, low-maintenance garden that supports biodiversity and sustainability. Happy gardening!
