Lavender (Lavendula spp.) is an herbaceous perennial that’s easy to grow and its blue-purple hues are complementary to roses. “Plants with shades of blue make great complements to typical rose colors,” says Tom Soulsby, senior horticulturist at Chicago Botanic Garden. “Blues found in lavender are appropriate if soil and light conditions permit.”
“Lavender is thought to deter pests such as aphids and whiteflies,” adds Ward Dilmore, founder and head landscape designer at Petrus, a luxury estate landscaping company. “Planting lavender near the borders of your rose garden is also a great way to attract pollinators.”
Lavender thrives in similar conditions to roses, requiring sunny locations with well-draining soil.

Boxwoods (Buxus spp.) are versatile green shrubs that create a perfect backdrop for roses, offering structure and texture for your landscape.
“Boxwoods can either be used in a parterre application, or as a beautiful backdrop to the garden and roses within it,” says Helaine Vrana, plant buyer at landscaping company R.P. Marzilli & Company. “Their texture creates a wonderful curtain effect allowing the rose’s color to pop.” They can also be more easily shaped than other evergreens, she adds.
These evergreens can grow in full or partial sun and prefer well-draining soil.

These hardy, disease-resistant perennials offer pops of color to complement roses. Like roses, clematis grow well in sunny conditions with well-draining soil.
