About Rieger begonia
Begonia hiemalis, commonly known as Winter Begonia or 'höstbegonia', is a hybrid begonia renowned for its abundant flowering. It features vibrant blooms in shades of red, pink, orange, and white, beautifully contrasting with its glossy green foliage. This plant is ideal for indoor settings, where it adds a splash of color during the colder months.
Native range
Horticultural hybrid, has no natural native distribution.
Care tips
It requires bright, indirect light; avoid intense direct sunlight to prevent scorching its leaves. Water when the top layer of the soil feels dry to the touch, but do not let it sit in water, as it is susceptible to root rot. It prefers a light, well-draining potting mix. A common mistake is overwatering and lack of ambient humidity, which can lead to bud drop.
