As part of taking care of your roses, you want to ensure they’re being planted near friendly plants that will provide them with help and protection. As well as what plants do not sit well beside your roses.
So that’s what I’m going to go over in this post. Starting with what requirements you ideally need out of a rose companion plant. So here’s what to focus on in general for your companion plants.
Choose smaller companion plants for roses, including knockout roses, that hide their bare lower branches. Include plants that attract pollinators, plants that deter pests and diseases, or that complement rose colors, with similar climate requirements, and that do not compete for nutrients and water.
But of course, there’s more to it than just that. For example, you need companion plants, that like roses, want a lot of sunshine, and generally like well-drained soil.
So let’s explore this a little further so you can get the right balance of companion plants in your rosebeds.
Companion plants for roses
It’s difficult to find one single plant that will provide all of these tasks, so mix them up to get a balance.
All of the following companion plant ideas offer something different to help your roses thrive. They can provide needed shade, act as a living mulch to retain moisture, attract pollinators, or give your garden a pop of color.
And I’ve added a handy table further below of the best companion plants that might help – as it looks at what you want to achieve around your roses – be it reducing pests, or plants for hot climates.
Companion plants for roses can be planted anywhere from 6 inches to 3 feet away from the base of your rose bush. When choosing companion plants, make sure to take into account the mature size of both the rose and the companion plant.
Here’s what plants grow best around roses based on what you’re looking to achieve.
Plants that complement the look of roses
Roses are top-heavy, so beneath that wonderful array of blooms is often a mass of branches and canes. This is perhaps the less attractive side of roses.
To help with this you ideally need companion plants for roses that will be of a similar or lower height so as not to obscure the roses, but which do obscure the leggy branches. But also you do not want to plant other plants too close to your roses as they don’t like to be crowded out.
Plants that flower at the same time, or earlier than the roses so as to provide a long season of color and interest. Preferably plants that bloom for long periods so that they provide some continuous blooms in between rose blooms.
Also, look for plants that have attractive foliage to add texture and contrast throughout the year. You don’t want a plant that is also very leggy and gnarly.

Plants that don’t compete for water or nutrients
Some plants are good at stealing water from everywhere around them. And this includes invasive plants too. This isn’t just surface water, but also plants that have widespread, and aggressive root structures
For roses, you need plants that won’t take all the resources. Some can be aggressive spreaders, but as long as they don’t compete for water, nutrients, or sunshine they might be okay.
Plants that encourage pollinators
Attracting pollinators to your roses is important to help them produce more flowers and also improve the quality of the flowers.
Look for companion plants that encourage bees, butterflies, and other pollinators.
Plants such as yarrow, lavender, and marjoram are great at attracting pollinators such as honeybees, bumblebees, leafcutter, and furrow bees.
Nasturtiums are another good companion plant for roses, as they attract hoverflies.
Hoverflies are important because their larvae eat aphids. So by attracting them to your garden, you’re helping to keep the aphid population down.
Some plants also have properties that can help to deter pests and rose diseases. For example, garlic is a great companion plant for roses as it helps to deter aphids, Japanese beetles, and rose chafers.
Mints are also good companion plants for roses as they help to deter caterpillars, cabbage white butterflies, and ants.

Plants that discourage pests and diseases
Companion plants can also help to keep pests and diseases away from your roses. Some companion plants have scents that naturally deter pests.
Not just flowers, but herbs such as chives, or other members of the onion family can be good for roses. They’ll help to keep aphids away.
Plants such as nasturtiums and marigolds release chemicals that deter pests such as aphids, slugs, and snails.
Basil is also a good herb used as a companion plant for roses. It helps to keep mosquitoes away.
Plants that prefer similar growing conditions
If you’re in a colder climate, then you clearly want to be looking at similar climate-related companion plants for roses to complement them. So, pay attention to the growing conditions your rose bushes like, and then find companion plants that have similar needs.
For example, roses need well-drained soil that’s high in organic matter. They also need full sun for at least six hours a day. So, some good companion plants for roses would be herbs like oregano, thyme, as well as lavender. All of these companion plants also like well-drained soil and full sun.

Plants that offer complementary colors
Roses come in a wide range of colors, from white to yellow to pink to red to purple. So, you have a lot of options when it comes to finding companion plants for roses that will complement their color range and make your garden look even more beautiful.
Some options for companion plants for roses that offer complementary colors include Yarrow (Achillea millefolium) which comes in shades of yellow, pink, and red. Coreopsis (Coreopsis spp.) comes in shades of yellow and red. And Salvia (Salvia spp.) which comes in shades of blue, purple, and white.
Plants that offer similar colors
If you want a more unified look in your garden, you can also choose companion plants for roses that offer similar colors.
Because roses come in lots of different colors you should easily be able to find ones that match the color, as well as provide other complementary aspects.

There are some flowers and plants you need to avoid too…
What NOT to plant with roses
There are naturally some plants you want to avoid using with roses. Typically these will be plants that grow taller than your roses and block out the light. Those that steal water, or plants that are generally invasive. Some also need shade or different soil pH.
Plants to avoid growing with roses include Echinacea, Fuchsia, Cosmos, Toad lilies, Bunchberry, and Leopard plants. Avoid large shrubs and trees, and do not plant too close as roses need some space to stretch out their limbs.
I’ll also single out cosmos in particular here as it’s one that springs to mind as being one to avoid for me.
Cosmos
The cosmos plant is very much an aphid magnet. So they will attract a lot of aphid interest. This may help keep aphids away from your roses, but I’d be more inclined to keep cosmos well away from your roses instead.
They would otherwise be a good companion for roses because they attract pollinators and help to prevent mildew _ and they’re pretty too.
