In this blog post, we explore purple perennials, highlighting seven that are best avoided due to their invasive nature or unsuitability for most gardens, and introducing thirteen stunning alternatives that promise to enhance any landscape with their charm and resilience.
1. Purple Loosestrife (Lythrum salicaria)
Beware of the Purple Loosestrife, a notorious invader. Known for its striking purple spikes, this perennial often finds itself unwelcome. Not only does it spread rapidly, but it also outcompetes native vegetation, causing severe ecological imbalances.
Many regions have banned its cultivation due to its aggressive nature. Once it takes root, controlling it requires significant effort. Its ability to dominate wetlands makes it a threat to biodiversity.
Gardeners should seek alternative purple perennials to avoid these issues. Choose plants that are both beautiful and environmentally friendly.
2. Common Periwinkle (Vinca minor)
The Common Periwinkle, with its glossy leaves and delicate flowers, might seem appealing. However, its allure quickly fades as it aggressively overruns landscapes. This vigorous spreader can choke native plants, impacting biodiversity.
Often found in shady areas, it forms thick mats, making it difficult for other plants to thrive. While its resilience is admirable, it requires constant management to control its invasiveness.
Gardeners desiring low-maintenance plants should look elsewhere. Consider more manageable purple flowering plants that harmonize with their surroundings.
3. Butterfly Bush (Buddleia davidii ‘Purple Emperor’)
While the Butterfly Bush, especially the ‘Purple Emperor’ variety, is a magnet for butterflies, its charm is deceptive. This perennial can become invasive in certain regions, spreading rapidly.
Its ability to self-seed results in colonies that outcompete native flora. Though there are sterile cultivars available, gardeners must choose wisely.
This plant’s invasive nature can lead to unintended consequences for local ecosystems. Consider opting for native plants that support pollinators without dominating the landscape.
4. Lamium (Lamium maculatum ‘Purple Dragon’)
Lamium, with its striking ‘Purple Dragon’ variety, offers unique foliage and vibrant blooms. However, its tendency to spread in moist environments can become problematic.
Though appealing as a ground cover, it becomes weedy, requiring frequent pruning and management. Its aggressive growth can lead to unintended garden takeovers.
Those seeking a controlled garden aesthetic should be cautious. Alternatives that provide similar visual appeal without the invasiveness should be considered for a balanced garden.
5. Creeping Bellflower (Campanula rapunculoides)
Creeping Bellflower, with its charming bell-shaped flowers, hides a more sinister side. This perennial spreads through rhizomes, making it incredibly invasive.
Once established, it’s challenging to eradicate, often requiring persistent effort. Its aggressive nature allows it to dominate flower beds, often at the expense of other plants.
For those passionate about maintaining a balanced garden, avoiding Creeping Bellflower is wise. Instead, consider alternatives that bring beauty without the maintenance headaches.
6. Tradescantia (Tradescantia × andersoniana)
Tradescantia, often appreciated for its lovely blooms, can turn unruly. Post-bloom, the plant often flops, creating a messy garden appearance.
While initially attractive with its soft purple flowers, the maintenance required to keep it tidy can be off-putting. Its sprawling nature may not suit those looking for neat, orderly gardens.
Gardeners looking for low-maintenance beauty should consider alternatives. Selecting perennials that maintain their form with minimal care will enhance garden aesthetics.
7. Russian Sage (Perovskia atriplicifolia)
Russian Sage, known for its airy lavender-blue spikes, can be too large for small spaces. Its sprawling nature often leads to a floppy appearance, which can detract from garden aesthetics.
