Companion Plants for Roses
by Diane Linsley

What are the best companion plants for roses?

Roses are lovely on their own, but they are even better with companion plants. Many garden designers have said that gardens should be a reflection of nature (minus the weeds). So why are there so many gardens with hybrid tea roses all in a row, and nothing but bare dirt below them?

Rose companion plants add beauty to the garden, and they also reduce problems with pests and diseases. My garden has over 600 varieties of plants, including about 50 roses. I never spray the roses with chemicals, and they are very healthy. This might be because the roses are interspersed with companion plants, which limit the spread of disease.

Sometimes in the spring, we have an infestation of aphids. But I don't worry because I know that ladybugs and other beneficial insects will show up for the feast when the weather warms. Hummingbirds also eat aphids. So flowers that attract hummingbirds are some of the best companion plants for roses.

I'm a fan of color schemes, so my favorite companion plants for roses are listed by color. When in doubt, plant blue flowers next to roses. They never fail to provide a beautiful contrast.
