Hardy begonias are one of the most popular plants in the world and for good reason. They are easy to care for, come in a variety of colors and shapes, and can be planted year-round. Hardy begonia plants also have some tricks that make them even easier to grow! In this blog post, we’ll cover some tips on how you can easily take care of your hardy begonias.

Origin and Species

The begonia genus consists of over 2000 species with about 200 commercially available. Hardy begonias are part of the Begoniaceae family and most common as house plants. The name “Begonia” is derived from the Portuguese word for BEGONE!, which became a popular exclamation in 16th century England when it was used to ward off the devil.

The begonias are native to Eastern and South America but most species have been introduced elsewhere in the world, especially as an ornamental plants. The Spanish first brought it back from Central America on ships to Europe where it was given its current scientific name, Begoniaceae Ventenat, in 1837.


Many begonia species are only hardy to USDA Zones 11 and 12, though some can be grown as far north as Zone six.

Some varieties of Begonias such as Fimbriata have been bred for colder climates and will survive down to zone four or five with some extra care.

Types of Hardy Begonias

There are many different types of hardy begonias that can be grown outdoors in most climates, but some are better than others for colder weather and these will help you choose the right variety to plant. Here is a list of those most commonly used as house plants by gardeners:


  • Begoniaceae hybrids like the popular Fimbriata, which can be grown in USDA Zone four with some extra care.


  • Warneckii is a scarlet or reddish variety that is hardy down to zone nine and has dark green leaves.


  • Alba is a white flowering variety of begonia, is hardy to USDA Zone six.
  • Begonias that have variegated leaves, like the Begonia x semperflorens and the begonias in the Biserrula group are also popular because they add a splash of color without requiring much care.

Sunlight Requirement

Begonias do best in full sun or bright, filtered light. They will not survive if left in the dark for long periods of time (more than twelve hours per day). Full-sun exposure to hardy begonias is essential and must be available year-round.

Soil Requirements

Begonias enjoy well-drained soil and should be planted in pots with a hole that is at least six to eight inches deep. This will give the roots more room for growth, as can happen with shallow or clay soils, which often stunt the plant’s root systems.


Hardy Begonia plants should be watered when the soil becomes dry. They should be allowed to go through a water-starved period at least twice per year and this will promote blooming in most varieties.


Begonias should be grown in humid environments, anywhere with 50% humidity or higher. They will not tolerate low-humidity conditions for long periods of time and this can lead to brown spots on the leaves that are both unsightly and harmful.


This plant does’nt need much fertilizer, but they do require a high Nitrogen level for healthy foliage growth. Use a fertilizer with a high N-P-K ratio or one that is specially formulated for foliage plants.


Fertilizing and water will be less effective if temperatures are too cold, so it’s important to know what zone you live in before planting your hardy begonias outdoors. The ideal temperature range varies widely depending on the zone you live in.

  • Hardy begonias should be planted outdoors when the night temperature is above 40°F, and it can drop down to below freezing during periods of dormancy without being harmed.


Pruning your hardy begonia plants will encourage new growth by making room for new flowers or leaves on the plant. Use a pair of pruning shears to cut off the dead, dried-out stems or any excess foliage from your plants. The more you trim, the easier it will be for new life to grow!


Pots should be replaced every two or three years to give the roots room to grow. Choose a pot that is at least one and a half times as large as the old one, but make sure that it has drainage holes in the bottom for water to escape easily.

Potting Soil

Different brands of soil will have different ingredients so it’s important to buy soil that is specifically formulated for begonias. It should have calcium, phosphorus, and potash mixed in with the peat moss or perlite so it will provide all of the nutrients they need.

Seasonal Care

The best time to plant hardy begonias is in the spring before temperatures warm up. Make sure that your plants are getting enough water, fertilizer, and humidity during this period because it can be difficult for them to thrive after going dormant in a cold climate.


The first step is to take off a leaf from the plant and allow it dry for a few days before planting in moist soil or potting mix. Make sure that you keep an eye out after watering so as not to overwater it; doing so may lead to the begonia developing root rot.

After two weeks, you should notice small roots coming out of the leaf and then it’s ready for planting in a pot or garden bed! Keep an eye on your new plant as they can be sensitive to drought during their first few months after propagation–be sure to water once every other day.

Propagation by seeds

Cut off the seed heads from your hardy begonias in fall after they have gone to sleep for the winter. Keep them dry and store them in a container with good ventilation until spring.

Make sure it is not too hot or cold, but rather somewhere around 50 degrees Fahrenheit (about 15 Celsius). Once morning temperatures are consistently above 60 degrees Fahrenheit (about 16 Celsius) or so, it is safe to sow the seeds in containers with sterile potting soil.

Planting Hardy Begonias

You can plant your begonias from seedlings or starter plants and they are very versatile when it comes to where you put them- They do well planted alongside other flowers, in containers, or even in urns. Hardy begonias have a reputation for being short and bushy plants that can easily be grown indoors because they require little care but are also rugged enough to grow outdoors!


The leaves need to be kept dry. If you’ve been dealing with fallen leaves or rain, make sure to clean the soil away from the base of your plant and use a board or something similar to cover it until all the water is off the top layer of soil. This will keep any moisture that may have gotten onto your leaf surfaces from rotting them prematurely!


Deadhead flowers once they fade to encourage more flowering stems – Hardy begonias are not typically self-sowing, but if you allow the seed pods on the plants to dry out and then shake them over a pot of moist soil in early spring, new plantlets will start growing from the seeds. Once planted, fertilize them to help them grow.

Think about your hardy begonias as perennials. They will not survive in a container for more than one year, but you can plant them out into the garden after they’ve grown a few inches tall or planted new plants each spring.


Hardy begonias are dormant in winter and need to go into a room with temperatures of 50 F or lower. This will make them tougher for the next season’s growth while also giving them time to develop new roots before becoming active again.

Life Span

Hardy begonias have the potential to live for up to forty years.

Disease and Pests

  • In the event that your begonia is afflicted by disease, consider using a fungicide.
  • If you have aphids, leafhoppers, or mealybugs: use soap and water to wash them off – if it’s scale insects, spray with horticultural oil. Be sure to follow all label instructions carefully as these chemicals could damage your plants.
  • If you have a problem, consider contacting an expert or looking for information about the specific disease online. In general, make sure to keep your plant’s leaves dry and inspect them often so that any damage–whether due to pests or natural causes like rot–can be prevented early on.


Consider keeping your plant out of reach from children and pets to avoid the risk of accidental ingestion.

Can I touch it?

Hardy begonias are generally safe, but you should exercise caution. If there is any question about how well a specific animal or person will tolerate this type of plant, use caution when handling them so as not to cause any irritation or allergic reaction.
