Did You Know?
1. Despite popular belief, not all begonias come back every year. While some begonias are perennials and can survive winter and bloom again the following year, others are annuals and will only last for one growing season.
2. There are over 1,800 different species and hybrids of begonias, showcasing a vast array of colors, shapes, and sizes. This diverse family of plants includes begonias with striking foliage, delicate flowers, and even ones that resemble miniature trees.
3. Begonias are named after the French botanist Michel Bégon, who was a significant patron of botany during the 17th century. The honor of naming this plant family after him was bestowed to the French naturalist Charles Plumier, who discovered begonias during a voyage to the Caribbean.
4. In some parts of the world, begonias have culinary uses. For example, in countries like Rwanda and parts of Central Africa, the leaves and stems of certain begonia species are cooked and consumed as vegetables or used in traditional medicine.
5. Some begonias have developed unique mechanisms for reproduction. For instance, the “angel wing” begonia (Begonia coccinea) has specialized stem nodes called “trumpets” that can carry leaf buds enabling them to grow into new plants when they touch the soil.
Begonias As Annuals Or Perennials
Begonias are a diverse group of plants, popular for their beautiful foliage and vibrant flowers. They are commonly used in sunny porch pots, ground bedding, and as indoor houseplants. The classification of begonias as either annuals or perennials depends on their life cycle and their ability to survive in different climates.
Most begonias are treated as annuals because they cannot withstand freezing winters outdoors. These frost-sensitive begonias cannot tolerate low temperatures and will die when exposed to frost. However, it is possible to keep them alive year-round by growing them indoors. By providing the right conditions including sufficient light, warmth, and humidity, these beautiful plants can continue to grow and thrive even during the coldest months of the year.
On the other hand, there are hardy begonias, specifically the Begonia grandis species, which are considered perennials. These hardy begonias can survive in USDA Hardiness Zones 6-9. They are known for their ability to thrive in shade and produce lovely pink flowers from midsummer to fall. Unlike their frost-sensitive counterparts, hardy begonias can withstand freezing temperatures and return year after year, enhancing the beauty of your garden.
Frost-Tender And Hardy Begonias
Growing frost-tender begonias indoors is a rewarding experience as they bring color and beauty to your home year-round. To ensure their success, provide them with the right environment. Ample sunlight, preferably bright but indirect light, is crucial. Keep them in a warm and humid spot, away from drafts and cold air.
Hardy begonias have specific growing requirements. They prefer shade and thrive in moist, organically rich, and well-drained soil. Regular watering, especially during dry periods, is important for their growth. Applying compost in spring provides necessary nutrients for healthy growth. Hardy begonias have a unique way of spreading and reproducing – they form bulblets on their stems that drop to the ground and grow into new plants. To control their spread, remove the small new plants or pair them with spring blooming bulbs for a stunning display.
Growing Hardy Begonias
Growing hardy begonias in your garden can be a delightful experience. These perennial plants are not only tolerant of a wide range of growing conditions but also produce stunning flowers year after year. To ensure successful growth, it’s important to provide them with the right conditions.
Firstly, hardy begonias thrive in shade. Plant them in an area of your garden that receives filtered or dappled light throughout the day. Too much direct sunlight can scorch their leaves and hinder their growth.
Secondly, they prefer moist, organically rich, and well-drained soil. Before planting, amend the soil with compost or organic matter to improve its fertility and drainage.
Proper watering is crucial for hardy begonias, especially during dry spells. They benefit from regular watering, allowing the soil to dry slightly between each watering. However, it’s important to avoid overwatering, as this can lead to root rot and other issues. Applying a layer of mulch around the base of the plants can help retain moisture in the soil, reduce weed growth, and regulate soil temperature.
Hybrid Garden Begonias
Hybrid garden begonias are a popular choice for container and bedding plants. These varieties offer lush foliage and provide instant bursts of color from late spring until fall. Unlike traditional begonia species, these hybrids can live longer than a year, making them a valuable addition to any garden or patio.
However, hybrid begonias are not as cold-hardy as their hardy begonia counterparts. In freezing areas, these plants will die once cold weather sets in. To maximize their lifespan, it’s important to take appropriate measures.
- Popular hybrid begonias should be planted in containers that are at least 18 inches in diameter. This allows for proper root growth and prevents overcrowding.
- The soil surface should be allowed to dry between waterings, as these begonias are sensitive to overwatering.
To keep hybrid begonias blooming all summer long, it’s recommended to add a slow-release fertilizer at planting time. This helps provide the necessary nutrients for continuous growth and flowering. Regular deadheading, or the removal of spent flowers, can also encourage the production of new blooms.
Additionally, hybrid begonias should be protected from cold temperatures. Once temperatures drop below 40℉, it’s important to cover them to prevent frost damage.
By taking these measures, you can extend the growing season of your hybrid begonias by a week or two.
- Plant hybrid begonias in containers at least 18 inches in diameter
- Allow the soil to dry between waterings
- Add a slow-release fertilizer at planting time
- Regularly remove spent flowers (deadheading)
- Protect hybrid begonias from cold temperatures by covering them below 40℉
Caring For Begonias In Different Conditions
One of the remarkable characteristics of begonias is their ability to tolerate a wide range of growing conditions, including both sun and shade. While frost-tender begonias thrive in sunnier conditions, preferring bright but indirect light, hardy begonias prefer shade and can handle areas with less direct sunlight.
Understanding the watering needs of begonias is crucial for their proper care. While begonias growing in shade require less frequent watering, those growing in full sun will need more regular watering to prevent dehydration. It’s important to allow the soil surface to dry between waterings, as overwatering can lead to root rot and other issues.
When it comes to fertilization, begonias benefit from the addition of slow-release fertilizer at planting time. This helps provide the necessary nutrients for healthy growth and abundant blooms. It’s important to follow the instructions on the fertilizer package for proper application and dosage.
In colder regions, begonias are sensitive to cold temperatures, and precautions should be taken to protect them. When temperatures are expected to drop below 40℉ in the fall, covering the plants can help extend the growing season by a week or two. This additional time can make a significant difference in enjoying the beauty of begonias.
Begonias are a versatile group of plants, suitable for a variety of purposes and growing conditions. While most begonias are treated as annuals due to their inability to survive freezing winters, hardy begonias offer the opportunity for perennial growth, brightening up gardens year after year. Whether you choose frost-tender begonias for indoor beauty or hardy begonias for a lasting garden display, understanding their specific needs and providing the right care is essential for their success. With the right conditions and proper care, begonias can bring joy and beauty to any landscape, from sunny porches to shaded gardens.

Frequently Asked Questions
What is the lifespan of a begonia?
Begonias, despite their ephemeral beauty, possess a relatively short lifespan. Despite providing optimal care, these plants typically live for only 2 to 3 years. Furthermore, specific types like the cane begonias, including the angel wings, can enter a dormant state if exposed to cooler temperatures, further affecting their overall longevity. Thus, while creating a moist environment through water evaporation can benefit the begonias, their lifespan remains relatively brief.
How can you tell if a begonia is perennial or annual?
To determine if a begonia is perennial or annual, one can consider its lifespan and frost tolerance. Annual begonias need to be replanted each year, while perennial begonias have the ability to survive for multiple years. However, it is important to note that even perennial begonias may be susceptible to frost damage and could be killed off if exposed to extreme cold temperatures. Consequently, it is recommended to plant both annual and perennial begonias after the last frost has occurred to ensure their optimal growth and survival.
Can you leave begonias over winter?
Yes, begonias can be left over winter depending on the type. Pure indoor begonias can be safely overwintered indoors, while outdoor begonias should be brought inside and kept in a cool and frost-free environment. Tuberous begonias, on the other hand, are typically cut back in autumn and overwintered in a dry, dark, and cool place either as a bare tuber or in dry soil. Overall, the best approach to overwintering begonias will depend on the specific variety and their individual needs.
Do begonias like sun or no sun?
Begonias thrive in environments with light shade or partial sun. They flourish when exposed to 4-6 hours of morning sunlight. However, some begonia varieties, like Non-Stops and Rex begonias, can also adapt well to deeper shade. So, while they enjoy some sun, begonias are versatile and can still thrive in areas with less sunlight.
