Rex begonias, scientifically known as Begonia rex, are a popular choice among gardeners and plant enthusiasts. These plants are native to tropical and semitropical regions and are considered perennials in those climates. However, in North America, where the climate is generally cooler, Rex begonias are typically grown as annuals or houseplants.
Being frost tender, Rex begonias cannot withstand cold temperatures and are susceptible to damage or even death if exposed to frost. Therefore, in regions with freezing temperatures, it is not possible for Rex begonias to come back every year without protection.
In areas with milder winters, some gardeners may attempt to overwinter their Rex begonias outdoors by providing them with proper protection. This can involve covering the plants with mulch or using frost blankets to insulate them from the cold. However, even with these precautions, there is still a risk of the plants not surviving the winter.
For most gardeners in North America, it is more practical to treat Rex begonias as annuals or houseplants. As annuals, they can be enjoyed for a single growing season and then replaced the following year. As houseplants, they can be grown indoors year-round, providing a touch of tropical beauty to your home.
Growing Rex begonias indoors can be a rewarding experience. They thrive in bright, indirect light and prefer temperatures between 60-75°F (15-24°C). They also appreciate high humidity, so misting their leaves or placing them on a tray filled with water and pebbles can help create a more humid environment.
When it comes to caring for Rex begonias, it is important to keep their soil consistently moist but not waterlogged. They should be watered when the top inch of soil feels dry to the touch. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and dry out.
In terms of fertilization, Rex begonias benefit from regular feeding during the growing season. A balanced, water-soluble fertilizer can be applied every two to four weeks, following the instructions on the product label. It is important not to over-fertilize, as this can lead to salt buildup in the soil.
Rex begonias are known for their stunning foliage, which comes in a variety of colors, patterns, and textures. They can add a touch of elegance and vibrancy to any indoor space. However, it is essential to keep in mind that their foliage is delicate and can be easily damaged by rough handling or excessive direct sunlight.
In my personal experience, I have found Rex begonias to be a delightful addition to my indoor plant collection. Their intricate leaf patterns and vibrant colors never fail to catch the eye and bring a sense of joy and beauty to my home. Although they may not come back every year as outdoor plants in my region, I have found great success in growing them as houseplants, providing them with the right conditions and care they need to thrive.
While Rex begonias are considered perennials in tropical and semitropical climates, they are typically grown as annuals or houseplants in North America. With their stunning foliage and easy care requirements, they can be a fantastic addition to any indoor space, adding a touch of tropical beauty. By providing them with the right conditions and protection from frost, it may be possible to overwinter Rex begonias outdoors in milder climates. However, for most gardeners, treating them as annuals or houseplants is the more practical approach.
