  • Natural Pest Control: Many plants, especially fragrant herbs, release scents that confuse or repel common rose pests like aphids and Japanese beetles. This is an eco-friendly best flowers to plant with rose bushes strategy that reduces your reliance on chemical sprays.
  • Attracting Beneficial Insects: Certain flowers are magnets for “good bugs” like ladybugs, lacewings, and hoverflies. These helpful predators feast on aphids and other pests, providing a free and natural security service for your roses.
  • Improved Soil Health: Some companion plants, known as “living mulches,” help keep the soil cool and moist. Their roots can also help improve soil structure and aeration over time.
  • Weed Suppression: Planting low-growing companions around the base of your roses helps to shade out and smother potential weeds, saving you time and effort on your knees.
  • Aesthetic Harmony: And of course, the visual appeal! The right companions can hide the less-attractive lower stems of rose bushes, provide a beautiful contrast in color and texture, and ensure your garden has continuous blooms even when your roses are between flushes.

Ready to find the perfect friends for your roses? Here are some of our favorite, time-tested companions. We’ve broken them down into categories to help you design your dream garden bed. Don’t worry—these flowers are perfect for beginners!

The Classics: Perennials That Love Roses

Perennials are fantastic because you plant them once, and they come back year after year. They form the structural backbone of a beautiful rose garden.

Lavender (Lavandula)
This is the quintessential rose companion. The silvery foliage and purple spikes of lavender create a stunning contrast against rose leaves and blooms. More importantly, its strong scent is known to deter aphids and even rabbits. Both roses and lavender thrive in full sun and well-drained soil, making them a perfect match.

Catmint (Nepeta)
If you want a soft, billowy, and incredibly low-maintenance companion, look no further than Catmint. Its cloud of tiny blue-purple flowers blooms for months on end. It’s tough as nails, drought-tolerant once established, and its fragrant foliage helps keep pests at bay. It’s fantastic for softening the edges of a border and hiding those bare knees.

Perennial Salvia (Salvia nemorosa)
With their vibrant, spiky flowers in shades of purple, blue, and pink, Salvias provide a wonderful vertical accent that contrasts beautifully with the rounded shape of rose blooms. They are a magnet for bees and hummingbirds but are generally ignored by deer and rabbits. They love the sun and are very forgiving.

Lady’s Mantle (Alchemilla mollis)
For a touch of elegance, you can’t beat Lady’s Mantle. Its scalloped, velvety leaves catch water droplets that glisten like jewels in the morning sun. The frothy, chartreuse-colored flowers are a lovely complement to any rose color. It’s an excellent choice for the front of the border to create a lush, full look.

The Hard Workers: Herbs as Rose Companions

Don’t underestimate the power of herbs! They are some of the most effective and sustainable best flowers to plant with rose bushes, working overtime to protect them.

Chives & Garlic (Allium)
Members of the onion family are famous for their pest-repelling abilities. Their strong scent can confuse aphids and prevent them from finding your roses. Some old-time gardeners swear that planting garlic near roses helps prevent the fungal disease black spot. Plus, you get to harvest them for your kitchen!

Thyme (Thymus)
Creeping thyme is a wonderful “living mulch.” This low-growing groundcover spreads to form a dense mat that suppresses weeds, helps retain soil moisture, and releases a lovely fragrance when you walk past. It’s incredibly drought-tolerant and tough.

Parsley (Petroselinum crispum)
It might sound surprising, but parsley is thought to deter some types of rose beetles. Its frilly, bright green texture also adds a lovely, delicate look to the base of your plants. Let some of it go to flower, and you’ll attract beneficial hoverflies.

The Showstoppers: Annuals for a Season of Color

Annuals live for one season, but they pack a powerful punch of color. They are perfect for filling in gaps while your perennials grow and for experimenting with new color combinations each year.

Sweet Alyssum (Lobularia maritima)
This low-growing annual is a powerhouse. It creates a carpet of tiny, honey-scented flowers that bloom nonstop from spring until frost. It acts as a living mulch and, most importantly, attracts legions of hoverflies, whose larvae are voracious aphid eaters. It’s a must-have for any rose garden.

Marigolds (Tagetes)
A classic for a reason! The pungent scent of marigolds is famous for deterring a wide range of pests, both above and below the ground (they can help repel harmful nematodes in the soil). Choose shorter varieties so they don’t overpower your roses.

Larkspur (Consolida)
For a touch of cottage garden charm, larkspur is an excellent choice. Its tall, elegant spires of blue, purple, and white flowers add height and a completely different shape to the garden, creating a beautiful layered effect behind or among your roses.

How to Plant Your Rose Companions: Best Practices for Success

Now that you have some ideas, let’s cover how to best flowers to plant with rose bushes to ensure everyone stays happy and healthy. Following a few simple rules will set you up for success and prevent future headaches.

Give Them Space! The Golden Rule of Spacing

This is the most important rule! Roses are prone to fungal diseases like black spot and powdery mildew, which thrive in damp, stagnant conditions. Good air circulation is your best defense.

When planting companions, make sure to leave at least 12 to 18 inches of space from the base of the rose bush. This gives both plants room to breathe and makes it easier for you to prune and care for your rose without disturbing its friends.

Matchmaker, Matchmaker: Consider Light and Water Needs

A successful partnership requires that both parties have similar needs. Since roses demand at least six hours of direct sun per day and prefer consistently moist, well-drained soil, their companions must also thrive in these conditions. Planting a shade-loving Hosta next to a sun-worshipping rose is a recipe for failure for one of them!

A Step-by-Step Planting Guide

Ready to get your hands dirty? This simple process works every time.

  1. Prepare the Soil: Before planting, amend the area with a generous layer of compost. This enriches the soil for both your roses and their new companions.
  2. Dig with Care: Dig a hole for your companion plant that is about twice as wide as its pot. Be mindful of the rose’s root system—try not to dig too close to the main stem.
  3. Plant Gently: Carefully remove the companion from its pot, gently tease out any circling roots, and place it in the hole at the same depth it was in the container.
  4. Backfill and Water: Fill the hole back in with soil, gently firming it around the plant’s base. Water deeply to settle the soil and eliminate air pockets.
  5. Mulch is Your Friend: Apply a 2-3 inch layer of organic mulch (like shredded bark or leaf mold) around both the rose and the new plant, being careful not to pile it up against the stems. This helps retain moisture and suppress weeds.

Common Problems with Best Flowers to Plant with Rose Bushes (And How to Avoid Them)

Even with the best intentions, you might run into a few hiccups. Here are some common problems with best flowers to plant with rose bushes and how to steer clear of them.

Problem: Overcrowding.
The Fix: It’s easy to get excited and plant too closely. Always read the plant tag to see the mature size of your companions and space them accordingly. If perennials get too large after a few years, don’t be afraid to divide them in the spring or fall—it’s good for the plant and gives you more to spread around your garden!

Problem: Competition for Nutrients and Water.
The Fix: Roses are heavy feeders. Ensure they get what they need by continuing your regular rose fertilization schedule. Amending the entire bed with compost annually provides a slow-release source of nutrients for everyone. The companions we’ve listed are generally not as demanding as roses, so they coexist peacefully.

Problem: Aggressive Spreaders.
The Fix: Some plants, like many types of mint (not Catmint!) or Bee Balm, can be overly aggressive and take over a garden bed. If you want to plant these, consider sinking them into the garden in a container with the bottom cut out to restrict their roots.

Frequently Asked Questions About Planting with Roses

What should you NOT plant with roses?

Avoid planting anything that will create dense shade or compete aggressively for root space and water. This includes large, fast-growing trees and shrubs. Also, steer clear of plants with vastly different soil or sun requirements (like ferns or hostas, which prefer shade).

Can I plant vegetables with my roses?

Absolutely! Many vegetables make great companions. As mentioned, garlic, chives, and onions are excellent pest deterrents. Carrots can help loosen the soil. Just be sure the vegetables you choose won’t grow tall enough to shade your roses.

Do I need to fertilize my companion plants?

For the most part, no. The regular feeding you provide for your roses, combined with an annual top-dressing of compost, will be more than enough to keep your companion plants happy and healthy. Focus your fertilizing efforts on the roses.

Your Beautiful Rose Garden Awaits

By choosing the best flowers to plant with rose bushes, you’re not just designing a prettier space—you’re working with nature to create a more resilient, lower-maintenance, and truly magical garden.

Start small. Pick one or two companions from our list, like Lavender or Alyssum, and see the difference they make. Gardening is a wonderful journey of discovery and experimentation.
