Begonia grandis, commonly known as Hardy Begonia, is a perennial plant native to China and Japan. It is known for its attractive foliage and delicate pink or white flowers. This plant goes dormant in the winter and re-emerges in the spring.
Begonia grandis prefers bright, indirect light and should be kept in moderate temperatures. It thrives in high humidity and requires evenly moist soil. Avoid letting the soil dry out completely between waterings.
土壤
This plant prefers well-draining loamy soil that retains moisture but does not become waterlogged. A mix of potting soil with added perlite or sand can improve drainage.

Prune Begonia grandis to remove dead or damaged leaves and to maintain its shape. Pruning can be done throughout the growing season as needed.
