Find Rose Companions
If you thought roses had to be relegated to a bed by themselves, think again. These flowering shrubs make great companion plants. By adopting an informal approach to design, you open the door to limitless creative options. There are benefits to playing garden matchmaker. Here are eight great reasons to find your perfect pairing.
- Extend the season with non-stop color by combining annuals, perennials, grasses and even other shrubs.
- Perk up a blah border by adding contrast and texture with spiky blooms (foxglove or grasses), bold, coarse leaves (brunnera), or frothy inflorescences (baby’s breath).
- Attract beneficial insects, birds and bees with a diverse palette. Did you know that hummingbirds gladly eat the aphids off of your rose bushes as they cruise for nectar?
- breate the ultimate cutting garden in your own backyard. Opt for long-lived, bouquet must-haves.
- Add structure with evergreen shrubs such as boxwood, senecio, sweet box or holly. Even herbs like sage, artemesia, rosemary and lavender help to shape a space.
- Exude charm and romance by under-planting with rambling vines like clematis, or by allowing your favorite rambling rose to clamber up a tree.
- Get the blues (the one color roses don’t offer) by planting sky-hued beauties like delphinium, veronica, iris and bluebeard (Caryopteris).
- Go organic with help from popular herbs. Pungent and potent, good old garlic, geranium, and mint send pests packing.
Rose Companion Planting Guide
- For a harmonious union, choose well-behaved plants with similar growth requirements as your rose.
- Install companions 12 to 18 inches away from roses to avoid disturbing the roots.
- Avoid plants that crowd or provide too much shade. Roses do not like to compete for water, nutrients or sunlight.
- Choose clumping-type perennials or grasses that stay contained instead of spreading beyond their boundaries.
What About Groundcovers?
At Heirloom Roses, we are often asked about groundcovers and which, if any, are suitable for planting around roses. Groundcovers are an inherently attractive idea for covering up the bare lower stems of roses, particularly hybrid teas, which tend to lose their lower leaves. However, many groundcovers are simply too aggressive to be compatible. Ground covers may also be in direct conflict with some of our most basic rose care, such as raking up leaves or deadheading, but that doesn’t mean you can’t use them if you pick the right ones. Consider your rose maintenance practices to ensure a good match. Do you regularly remove spent blooms during the summer? Some groundcovers resent being trampled on while others are tolerant.
Ground Covers We Love
- Those that take light foot traffic, such as the Steppables collection, which includes violets, sedums and strawberries.
- Prostrate, ground-huggers like woolly thyme, Corsican mint or blue star creeper.
- Tough growers such as dwarf mondo grass withstand some raking.
- Summer annuals that offer seasonal color, yet doesn’t get in the way of fall cleanup or mulching. Try alyssum, lobelia, lantana, petunias, summer snapdragon (Angelonia), million bells (Calibrachoa), verbena and pinks (Dianthus).
Companions for Pest Control
True companion planting is rooted in permaculture and vegetable gardening. Most organic growers know the secrets that marigolds, geraniums, basil, and mint hold in repelling pests, along with the aforementioned garlic (as well as chives, ornamental and edible onions). Did you know that members of the Allium family are reported to increase the perfume of roses and help prevent black spot in addition to warding off insect pests?
Ward off Pests the Natural Way
- Onions repel aphids, weevils, borers, moles
- Garlic repels aphids, thrips and helps to fight black spot and mildew. For best results, you may need to plant garlic with roses for several years.
- Chives repel many pests
- Basil repels aphids, mosquitoes, moles
- Geraniums repel Japanese beetles, aphids, and rose beetles
- Marigolds discourage harmful nematodes, repels pests, and is a trap plant for slugs
- Parsley repels rose beetles
- Mint deters ants and aphids
- Tansy deters flying insects, Japanese beetles
- Tomatoes help to protect roses from black spot
