Companion Plants For Little Devil Ninebark

Finding companion plants for a particular plant species requires thinking along two lines:

1. The companion plants should not compete for resources with the parent plant. Instead, both species should complement each other’s growth.

2. Both the parent plant and the companion plants should look aesthetically pleasing together.

For that matter, Little Devil Ninebark also has companion plants that relish growing around it. Common companion plants to Little Devil Ninebark include Garden Phlox, The Coneflower, and the Russian Sage.

Let’s get down to details about these plants. 

Garden Phlox (Phlox paniculata)

Phlox is a Greek word for flame, and the naming stemmed from some of the plant varieties having intense flower colors. The plant is a native of several states: New York, Iowa south, through Georgia, Mississippi, and finally Arkansas.

The plant is an upright growing perennial; however, different species have different growth patterns. Garden Phlox is an excellent companion to little devil ninebark, and they will form a perfect color blend when you grow them together.

Some are low-growing (creepers) and work best as ground covers. You will find the tall Phlox handy for a colorful background plant; medium-height varieties can fit anywhere.

The creeping Phlox helps fill spaces, especially under trees. It’s also suitable for forming trails on slopes.

The plant is popular amongst gardeners thanks to its billowy blooms and long season of flowering. Early Spring is when Phlox begins blooming, and some varieties will go on until the hard frost that comes in fall.

Its range of colors and cultivars is quite broad, leaving you spoilt for choice. Garden phlox thrives well in zone 4-8.

It grows up to a height of 4 feet with some varieties going beyond that. It spreads 2-3 feet wide on stiff stems with pointed, elliptic, dark green leaves that can grow up to 6 inches long. 

Planting Garden Phlox

You can grow Phlox in your garden from transplanting or cuttings. This option is more effortless than propagation through seeds.

The best time for planting is in Spring; at this time, your plant will be safe from the effects of frost. They love fertile soils that are well-draining and evenly moist.

When preparing your garden bed, loosen the soil and ensure it’s 12-14 inches deep. Mix the soil with a 4-inch layer of compost.

Phlox lighting requirements vary by species. As a general rule, maintain a sunlight exposure of 6 hours daily. 

Coneflower (Echinacea purpurea)

The coneflower is a popular plant in the Eastern parts of North America. You will also find it among the most common plants in the Mississippi and the Ozarks.

It loves growing in the prairies, dry open woods, and barrens. Apart from E. purpurea, other common varieties include E. pallida, E. paradoxa, and E. tennesseensis.

The plant is drought resistant which makes it a good perennial. You can easily grow it in your garden, and the good part is that it will bloom for months.

Coneflowers produce excellent cut flowers. Their flowers range from colorful shades of yellow, pink, orange, chartreuse, and red.

You will also love its flower forms that range from horizontal ruffs, standard shuttlecock, and Powerpuff center doubles. Coneflower thrives in varied zones, but the typical is 3 through 9.

The plant grows to a height of 5 feet tall and will spread as wide as 2 feet. It loves total sun exposure, but it can also survive in partial shade.

If you are growing them in hotter climates than their ideal habitats, maintain a partial afternoon shade to prevent burning. Coneflower blooms from June to August and beyond. 

Planting Coneflower 

Coneflowers love sunlight, and you should ensure to plant them in areas that receive at least 6 hours of daylight. Too much shade will make your plant susceptible to diseases such as powdery mildew.

Seedbed preparation is more or less like the one for garden phlox. Loosen the soil to a depth of 12 inches and add a four-inch layer of compost to the topsoil.

Your seeds should germinate in 3-4 weeks. True leaves form after 12 weeks.

If transplanting the seedlings, we advise digging holes that are twice as large as the pot. This allows the plant’s root ball to be at the same level as the soil top, thus providing room for new roots to grow.

Russian Sage (Perovskia atriplicifolia)

Russian sage is a herbaceous perennial that is loved for its lavender-purple flowers and fragrant grey-green foliage. The plant is known for growing in coastal areas.

It thrives well in hardiness zones of 4-9. However, you will need to protect the plants you grow in zone 4 from winter.

As long as the roots survive, you should see new growth in Spring. The Russian Sage is a perfect companion of Little Devil Ninebark and will also grow alongside other border plants like rudbeckias, echinaceas, and eryngiums.

Mature Russian sages can grow up to a height of 4 feet and 3 feet wide. They grow tall but bend over due to the weight of their flowers.

Russian Sage is a drought-resistant crop that can thrive in hot and dry areas. That explains its love for full sunlight.

The plant begins blooming in July through to August with a hint of their colors, and the flowers gain entire brilliant colors over time but eventually become subdued again.

Planting Russian Sage

Grow the plant in well-drained soils during fall or early Spring. Add a soil mix (potting mix) with fertilizer during planting to boost growth and encourage blooming.

Ensure to grow the plant in sunbathed locations to bloom. Partially shaded areas make the plant sprawl.

Observe a spacing of 2-3 feet during planting and maintain regular watering during dry spells to keep them growing; however, they may not need much water since they can withstand drought.

When doing mulching, we advise using gravel instead of organic matter because it enables moisture evaporation. If you are doing planting to have a hedge, consider a spacing of 50 cm apart.
