Begonia × Hiemalis
Often called the Rieger Begonia or Winter Begonia, this stunning hybrid is the ultimate "living bouquet." Created by crossing tuberous begonias with rare succulent species, it was specifically designed to provide a massive explosion of color during the shorter days of the year. It’s a favorite for gifting, known for its rose-like blossoms and glossy, lush foliage that seems to glow under indoor lights.
The Begonia × Hiemalis was a horticultural breakthrough in the mid-20th century. Before this hybrid existed, most begonias needed very specific seasonal cues to bloom; breeder Otto Rieger perfected this variety so that it could bloom almost year-round, regardless of day length!

To grow Begonia × Hiemalis plant, here are some steps you can follow:


To fertilize Begonia × Hiemalis, use a balanced liquid fertilizer with equal parts nitrogen, phosphorus, and potassium. Dilute the fertilizer to half strength and apply every two weeks during the growing season, which is usually spring to fall. Water the plant thoroughly after fertilizing to help distribute the nutrients to the roots. Avoid over-fertilizing as it can damage the plant.
The ideal soil type for Begonia × Hiemalis is a well-draining, nutrient-rich soil that is slightly acidic with a pH range of 5.5 to 6.5. It should be light, airy, and loamy in texture to ensure good aeration and water retention. The soil should have the ability to hold sufficient moisture to promote healthy growth and prevent the plant from drying out completely between watering sessions. A mixture of compost, peat moss, perlite, and vermiculite can be used to create a well-draining and nutrient-rich soil. It is also recommended that the soil be amended with slow-release fertilizers to provide essential nutrients for the plant's growth. As with any plant, it is important to ensure that the soil is free of harmful chemicals and toxins that may negatively impact the health of the plant.
Begonia × Hiemalis can be propagated through several methods including leaf cuttings and stem cuttings.
To propagate Begonia × Hiemalis through leaf cuttings, choose a healthy leaf from the plant and make a clean cut with a sharp knife. Place the leaf in a small pot filled with well-draining soil, ensuring that the bottom of the leaf is buried in the soil. Keep the soil moist and place the pot in a warm, bright location with indirect sunlight. Roots should begin to form in a few weeks, at which point you can transplant the cutting into a larger pot.
To propagate Begonia × Hiemalis through stem cuttings, select a healthy stem with several leaves and make a clean cut just below a leaf node. Remove the lower leaves from the cutting and place it in a small pot filled with well-draining soil. Keep the soil moist and place the pot in a warm, bright location with indirect sunlight. Roots should begin to form in a few weeks, at which point you can transplant the cutting into a larger pot.
Both leaf and stem cuttings should be kept in a warm, humid environment to encourage root growth. Mist the cuttings regularly to keep the humidity high and remove any dead or decaying leaves. With proper care and attention, Begonia × Hiemalis cuttings should root successfully and grow into healthy plants.
