Protect Rock Trumpet Flowers By Growing These Companion Plants Alongside Them

Often, the most beautiful flowers are the most sensitive, and the flowers of the rock trumpet (Mandevilla macrosiphon) fit into that category. They add a tropical feel to any garden, and even though they are generally quite hardy, they aren't a fan of cold winds or chilly weather. On top of that, they are susceptible to pesky aphids and spider mites. To give your rock trumpet the best chance to thrive, companion planting can elevate the beauty of your garden while also providing protection to the delicate flowers.

One of the best companions for rock trumpets is the tropical hibiscus. Hibiscus plants similarly add a burst of color, and they can handle the same growing conditions. They also have broad, dense leaves that help to shield your rock trumpet vines from cold drafts and gusty winds, giving them an extra layer of protection. There are many beautiful hibiscus flower varieties for a colorful garden, with vibrant flowers that perfectly complement one another. It's a win-win.

Dipladenia, a very close relative to the rock trumpet, is another excellent companion plant. They are both of the same genus — Mandevilla — so they have the same sturdy growth habits and care requirements, making them a perfect pair. However, dipladenia is more shrub-like, while rock trumpet has a vining nature. Because of its density, dipladenia can help shield your rock trumpet's delicate stems; plus, its slightly smaller, bright blooms add some aesthetic contrast.

Coleus and lantana are two more great choices that can act as natural companions to the rock trumpet. Coleus is a popular choice for gardens in general since it has such stunning foliage, with colorful burgundy, lime green, and pink leaves, along with the fact that it is low maintenance. With its bushy growth and dense leaves, it can also help protect your rock trumpet. Additionally, coleus does well in partially shaded areas, which will provide protection from the harshest midday sun.

Lantana has some of the most visually interesting blooms you'll ever see, with colorful clusters of little flowers that add vibrancy to any landscape. It's a really hardy option that will also help block out strong winds, with a growth habit that works great for covering the lower parts of the rock trumpet vines. It will also bringing more pollinators into your yard and garden, like bees and butterflies.

Marigolds, with their bright, cheerful flowers, are another excellent companion for your rock trumpet. These low-maintenance plants not only add color to your garden but can also deter pests. Marigolds naturally repel a variety of insects, such as aphids and spider mites. Planting marigolds around your rock trumpets also helps to create a layered display of color that adds to the tropical feel of your garden.
