Begonia semperflorens

flower

Small begonias, commonly known as wax begonias, are compact flowering plants prized for their ability to thrive in shade and partial shade conditions. These plants produce delicate flowers in shades of pink, red, and white, along with attractive foliage that ranges from green to deep bronze. They are excellent for border edging, containers, and shade gardens where many other flowering plants struggle.

Growth Stages

1

Seedling

2-3 weeks

Tiny leaves emerge and seedlings develop their first true leaves. Very delicate with shallow root systems.

Maintain high humidity and consistent moisture. Use seed starting mix. Keep temperature around 70-75°F. Provide gentle light.

2

Vegetative Growth

3-4 weeks

Plant develops bushy foliage with multiple stems and leaves. No flowers present yet. Leaves become more vibrant in color.

Pinch back growing tips to encourage bushiness. Maintain consistent watering and humidity. Gradually acclimate to garden conditions if starting indoors.

3

Budding

1-2 weeks

First flower buds begin to form in leaf axils. Plant continues to grow and become more compact.

Maintain regular watering and ensure adequate filtered light. Begin light fertilizing with balanced fertilizer every 2-3 weeks.

4

Flowering

8-12 weeks or until frost

Small delicate flowers open in clusters, typically in white, pink, or red. Blooms continuously throughout growing season.

Deadhead spent flowers to encourage more blooms. Continue regular watering and fertilizing. Monitor for pests and diseases.

5

Senescence

Variable; until frost or end of season

Plant growth slows as temperatures cool or day length decreases. Flowering may diminish in late fall.

Reduce fertilizing. Can be brought indoors before frost for winter houseplant care, or allow to decline naturally as annual.
