There are more than 900 species of begonias and many of them are commonly grown in household gardens. Begonias are popular, as they need basic care, minimal fertilization and bloom nearly throughout the year. There is some confusion regarding the classification of begonias as many varieties have unique features. However, now the following types of begonias are universally accepted:
1. Tuberous Begonias — these are hybrids of native South American begonias.
Large flowers are the defining feature of tuberous begonias.
Grow well in semi-shaded areas and need protection against strong winds.
Winter frost could immediately kill them — need insulation during winters.
2. Rex Begonias — not famous for their flowers but their exotic foliage.
Leaves have a bright-green shade that is uncommon in most begonias.
Regarded as a difficult plant to grow since the temperatures sensitivity is higher than other begonias.
Need sustained moist conditions with humidity around 70%.
3. Cane-like Begonias — the stem is very stiff and can withstand the strongest of winds, giving this begonia its defining name.
They are also called angel wing begonias and true-tree begonias.
One of the few begonias that is suited for both outdoor gardens and pots.
Mature angel wings can reach a height of about 10 feet.
4. Semperflorens Begonias — usually called wax or bedding begonias.
Grown mainly for their bronze and green-colored foliage.
Ideal for dry conditions — can withstand small episodes of droughts too.
5. Rieger Begonias — also called Blush or Hiemalis begonias.
One of the few winter-flowering begonias.
It can be killed by the slightest amount of water stagnation.
The flower hues are varied, ranging from scarlet to pinks and pastels.
6. Trailing Begonias — also called Trailing Scandents.
Used for decoration purposes, typically in hanging baskets.
Can also be used as climbers in the garden.
Propagating them in the garden easy by using stem or tip cuttings.
7. Shrub Begonias — almost an identical image of the Trailing Scandents but they have a thicker foliage. They flower occasionally but mostly grown for their lavish leaves and thick stems.
Ideal for potting and being placed indoors — being constantly shaded is not an issue.
8. Thick-stem Begonias — the classification status of this variety is still not clear.
Refers to all the wild-growing begonias that have thick stems, rising up to 8 feet or more, and still haven’t been grouped under any of the above-mentioned begonia types.
