Begonia

( beh - GOH - nee - uh )

At-A-Glance Information

This genus of flowering herbaceous perennial plants is one of the largest, and is native to moist, tropical areas of the globe. Some species are grown indoors as ornamental houseplants, and thrive in these conditions. Flowers have sepals but no true petals. Begonias are cultivated in many different ways, including as terrarium plants, indoor or greenhouse specimens, in hanging baskets or containers outdoors, or in mixed beds or borders. They are commonly planted en masse in the landscape for a striking effect. Take care when planting these flowers in the landscape or indoors, as plant parts are toxic to pets, and humans can have negative reactions as well.

Begonia Species and Varietals

The genus Begonia was first named by Charles Plumier, French botanist and naturalist. The moniker was adopted later by Linnaeus to honor Michel Bigon, a former governor of Haiti. The genus Begonia is in the plant family Begoniaceae, and contains over 2,000 species. The best growing zones for these plants vary depending on the species grown; for more information, see the descriptions below. To find your zone, click here: Zone Map.

Caring for Begonia

Plant Begonias in an area of the garden that gets full sun to full shade. These plants can tolerate a wide variety of sun exposures, which vary depending on the species grown. When grown in full sun, most species will appreciate some late afternoon shelter from the direct rays of the sun. They are best planted in the early morning or evening, when temperatures are consistently 50 degrees Fahrenheit or warmer. Do not attempt to plant Begonias before the last frost of your area has passed. Soil should be well-draining and relatively rich in nutrients. If local soils are particularly poor or do not drain well, make sure to amend the planting area with plenty of organic material and compost, working it into the soil before installing plants.

After planting Begonias, apply a thick layer of mulch on top of the soil around the base. This will help retain soil moisture and suppress weed growth. Keep mulch away from the plant stems, as this can encourage an environment for root rot issues to take hold. Water new plantings regularly as they develop a strong root system. Mature plants also appreciate consistently moist soil; irrigate whenever the top inch or two of soil is dry to the touch. Fertilize these plants yearly with a dressing of organic compost, pulling back mulch to apply before gently working it into the soil, watering, and then replacing the mulch. Prune plants to remove spent flowers and any dead, damaged or diseased foliage. Protect from cool temperatures (anything under 50 degrees Fahrenheit has the potential to damage plants). In cold-winter climates, grow Begonias as annuals outdoors.

Growing Begonias Indoors
In addition to being classic garden ornamentals, Begonias are also commonly cultivated indoors as houseplants. Indoor growing can open up horticulturalists to cultivating a wider variety of Begonias, including those from more tropical regions of the globe. Plant Begonias in rich, well-draining potting mix in a container that has adequate drainage holes. Place the container in a spot in the house that receives bright, indirect light. Species with darker leaves will have more pronounced color the more light they receive. Water whenever the top inch of soil feels dry to the touch. Indoor plants need to be fertilized with a general houseplant fertilizer every springtime to support the season's growth and flowering.

Propagation

Begonia plants can be propagated either by using cuttings or from seed. To ensure that your propagated plant will have the exact same qualities and characteristics as the parent plant, use the cutting method. If you would like to experiment and see what plant you can grow from seed, just keep in mind that it will not necessarily be the same as the parent plant. To propagate your Begonia, follow the instructions below:

Propagating Begonia by Cutting
  1. Gather your materials. You'll need a clean, sanitized, sharp pair of garden shears, rooting hormone, a pencil, and a 3-inch pot filled with well-draining compost or other organic material. If you don't have any potting medium on hand, you can make some. Just mix together equal parts (by volume) moss peat and horticultural-grade sand or grit sand.
  2. In spring or early summertime, choose the plant that you'd like to propagate. Ensure that this plant has had a good watering the night before, as this will improve the chances your cutting will take root. Cut one or more 6 inch portion(s) of the end of a non-blooming branch and strip the leaves off of the lower half. Make a hole in your planting medium by pushing your pencil into the soil. Dip the end of the stem in rooting hormone, and plant it in your pot. Fill in soil around the cutting to support it, but do not pack it down too much.
  3. Moisten with water, and ensure that the pot has good drainage. Your pot should be kept in warm, sunny conditions indoors (and not in direct sunlight). Water whenever your soil is dry under the top layer. After about four to six weeks have passed, your cutting should be rooted. When you notice new growth, you'll know you have roots.
  4. Keep your new plant in an area with bright light (though not direct sunlight) and temperatures between 55 and 70 degrees Fahrenheit. Ensure that the soil stays moist, but not wet, until the next spring, when you can transplant it to its new home. Ensure that the last frost of the year has occurred before doing this, as it can seriously damage your new shrub.

Propagating Begonia by Seed
  1. Keep in mind that the plant you get from seed will not necessarily mimic all of the characteristics of the parent plant. To propagate by seed, you will need a paper bag, a pot or tray filled with well-draining compost or other organic material, a spray bottle and a fork. If you don't have any potting medium on hand, you can make some. Just mix together equal parts (by volume) moss peat and horticultural-grade sand or grit sand. You will also, after a few weeks, need individual 3-inch pots for each seedling that grows. 
  2. Water your prepared seed tray or pot filled with soil, and ensure that good drainage is occurring. Place your seeds in your prepared pot or seed tray about a quarter inch to a half-inch under the soil surface. Cover them with soil and water with your spray bottle. Place your tray of seeds in a warm area that receives bright, indirect light. A greenhouse is the most ideal climate, but a planting tray inside a window will do as well. Germination usually takes 7-14 days from sowing. Once you begin to see seedlings sprout and they are able to be handled, transplant them to their own individual 3-inch pots, filled with the same potting medium as described in Step 1. Loosen the seedlings from the potting medium by digging down with the tines of your fork about an inch and a half, gently working the seedling up until it is out. Then, replant the seedling in its individual pot.
  3. Keep the seedling's potting medium moist, but not wet, by spraying the soil with your spray bottle. Keep your new plant in an area with bright light (though not direct sunlight) and temperatures between 55 and 70 degrees Fahrenheit. Ensure that the soil stays moist, but not wet, until the next spring (after the danger of frost has passed), when you can transplant it to its new home.

Begonia seeds are very tiny, and are typically reddish-brown.
