Is Begonia a Shade Plant? A Complete Guide to Growing Begonias in the Shade

Begonias are beautiful flowering plants that come in a wide variety of colors shapes, and sizes. With over 1800 species, there is a begonia for virtually every garden situation. One of the most common questions gardeners have is whether begonias can be grown in the shade. The short answer is yes! Many begonia varieties thrive in shady locations.

We will talk about everything you need to know to grow begonias in the shade in this full guide. We’ll talk about the different kinds of begonias, why they make great shade plants, give you some tips for success, and suggest the best varieties that do well in shade. Let’s get started illuminating those shady corners with vibrant begonias!.

An Overview of Begonia Types

There are three main groups of begonias:

• This type of begonia grows from tubers and has some of the biggest and brightest flowers of any shade plant. The flower colors are orange, pink, red, white, and yellow. Tuberous begonias need to be kept out of the sun, especially when it’s very hot outside.

• Wax begonias – Also known as fibrous begonias, these plants have smaller clustered flowers. Wax begonias are one of the most versatile, tolerating both shade and some sunlight. Those with darker leaves can handle more sun.

• Rex begonias – Grown for their colorful and striking foliage, Rex begonia flowers are rather insignificant. The beautifully patterned leaves come in shades of green, red, silver, pink, and purple. Rex begonias thrive in shade and humid conditions.

Why Begonias Make Great Shade Plants

There are several reasons why begonias perform so well in shady garden locations:

• Begonias originate from tropical regions, so they are adapted to growing in the shelter of larger plants and trees. Dappled sunlight or bright shade mimics their natural environment.

• The leaves of many begonia varieties have iridescent qualities that allow them to maximize whatever light is available in shady conditions.

• Compared to many other flowering plants, begonias don’t need as much bright light to bloom. Shade reduces the chance of stressed, wilting leaves.

• High humidity is ideal for begonias. Shaded areas usually have more humidity than places that get a lot of sun.

• Begonias require less watering and thrive in the moist soils typical of shady gardens. Overwatering in full sun often leads to root rot.

Growing Begonias in the Shade

When planting begonias in a shady garden spot, follow these tips for success:

• Select begonia varieties suited for shade. Check plant tags or descriptions to be sure your variety can handle low light. Rex, tuberous, and wax begonias are all good choices.

• Give begonias rich, organic soil that retains moisture. Compost and peat moss create an ideal growing medium. Mulch to keep soil evenly moist.

• Water begonias when the top inch of soil becomes dry. Avoid wetting foliage, which can promote diseases like powdery mildew. Drip irrigation works well.

• Shelter begonias from hot afternoon sun. A few hours of early morning sun is often tolerated, but afternoon exposure leads to leaf scorch.

• Choose faster growing begonias to fill in shade gardens quickly. Wax begonias and the trailing ‘Whopper’ hybrids are quick to establish.

• Fertilize every 2-3 weeks during the growing season with a balanced liquid fertilizer or timed-release beads. Avoid overfeeding.

• Prune back leggy growth and deadhead spent blooms to encourage new flowering. Pinching also thickens growth.

• Bring containerized begonias indoors before first frost. Most cannot tolerate any freezing temperatures.
