Companion Planting in Shade Gardens
I didn’t think much about Companion planting in shade gardens, and the result wasn’t so good at times. However, most plants I added to the shade gardens lived harmoniously and thrived. I probably got lucky, and there are very few plants you want to avoid adding to your shade gardens Giving thought to the plant’s habits will help you avoid my mistakes By carefully selecting and arranging your plants, you can better achieve:
- Improved Nutrient Cycling: Certain plants can draw specific nutrients from the soil, making them available for their companions. This natural exchange helps to maintain the balance and fertility of the soil.
- Enhanced Pest and Disease Control: Some plants have natural pest-repelling properties or can attract beneficial insects that prey on common garden pests. Strategically placing these plants can create a self-regulating ecosystem.
- Maximize your Space Utilization: By pairing plants with different growth habits and root structures, we can maximize the available space in our shade gardens, ensuring that every inch is put to productive use.
- Boost Biodiversity: A diverse shade garden supports a broader range of wildlife, including pollinators, birds, and beneficial microorganisms, creating a thriving and resilient ecosystem.
Understanding Shade Loving Plants and Their Needs
Before we dive into the specifics of finding the perfect plants for your shade garden, it’s essential to understand the unique requirements of shade-loving plants. These plants have adapted to thrive in low-light conditions, often requiring specific soil, moisture, and nutrient levels. By understanding their individual needs, we can create a successful shade garden.
Plants to Avoid Planting Together in Shade Gardens
Just as there are harmonious plant pairings, certain combinations should be avoided in shade gardens. These incompatible plants may compete for resources, inhibit each other’s growth, or even release allelopathic chemicals that can harm their neighbors. Some common examples to steer clear of include:
- Aggressive Spreaders: Plants with a tendency to aggressively spread, such as some groundcovers or invasive species. I planted the ground cover Snow on the Mountain also known as Bishop’s Weed or Goutweed. I fell in love with its delicate pale green leaves with white borders. I hadn’t done my homework and didn’t know that it was an aggressive spreader. It spreads via rhizomes, and trying to dig it up and remove it usually breaks up the rhizomes into lots of little pieces. Each rhizome piece will form a new plant, resulting in even more plants than before. What a challenge. I finally gave up on removing it and put a border around the area where it was so it wouldn’t take over the shade garden. The Ostrich fern was another mistake. The ostrich fern is the fern that is grown for the shoots it sends up in the spring. These shoots are the source of the fiddlehead ferns. I harvest the fiddleheads In the spring and saute them in butter and shallots for a delicious side dish. This is a definite plus for the Ostrich Fern. However, it can quickly overtake and crowd out more delicate shade-loving plants.
- Heavy Feeders: Plants that require high levels of nutrients can deplete the soil, leaving little for their more modest companions. Astilbe are heavy feeders.
- Incompatible Moisture Needs: Pairing plants with vastly different water requirements can lead to one thriving while the other struggles or succumbs to disease.
- Shade-Intolerant Plants: Introducing sun-loving plants into a shaded environment can result in stunted growth or even death, disrupting the delicate balance of the shade garden.
We can create a harmonious and productive shade garden by understanding these potential pitfalls.
Shade Garden Plants that Thrive Together: Examples and Recommendations
Let’s explore the combinations of plants that thrive in your shade garden.
- Ferns and Hostas: These two iconic shade plants work in perfect harmony, with the ferns providing a lush, textural backdrop for the bold, sculptural leaves of the hostas. That sounds lovely, and when I planted Ostrich Ferns with hosta, I envisioned that perfect harmony. However, what I got was something else altogether. The Ostrich Fern, while lovely to look at, is an aggressive spreader, and in about 5-7 years, their spreading rhizomes had overrun the hostas, wiping out many of the different hosta species I had planted among the ferns. Had I done my homework, I would have realized that
ferns have two primary growth forms: creeping and crown-forming. Creeping ferns grow from trailing rhizomes or stolons and spread quickly through the garden. Their fronds are borne in loose clusters or lines along the rhizome. Crown-forming ferns grow from upright rhizomes and carry their fronds in a circle or tight vaselike cluster. You plant ferns with other shade plants and choose a non-spreading variety like the Lady Fern, Painted Lady Fern, and Kimberly Queen Fern. - Coral Bells and Astilbes: The delicate, bell-shaped flowers of the coral bells pair wonderfully with the feathery plumes of the astilbes, creating a captivating display.
- Bleeding Hearts and Columbines: The arching, heart-shaped blooms of the bleeding hearts are perfectly complemented by the whimsical, spurred flowers of the columbines. In my shade garden, the bleeding hearts tend to be a bit more aggressive than the Columbines, so I remove the ones that have self-seeded beyond where I want them to be every few years.
- Tiarella and Heuchera: These two shade-loving foliage plants offer a diverse palette of colors and textures, from the delicate, maple-like leaves of the Tiarella to the bold, ruffled foliage of the Heuchera.
- Barrenwort and Epimedium: These low-growing, mat-forming plants create a lush, carpet-like ground cover that thrives in the shade. The delicate, spurred flowers of the Epimedium add a touch of elegance. Although they are ground-cover plants, they spread slowly via rhizomes.
You can create a visually stunning and mutually beneficial shade garden by carefully selecting and arranging these harmonious pairings.
How to Create A Plan for a Successful Shade Garden
Developing a successful companion planting plan for your shade garden requires forethought and strategic planning. Here are the key steps to follow:
