About Hardy begonia
Begonia grandis, commonly known as the hardy begonia, is a tuberous perennial begonia native to Asia, renowned for its ability to survive cold winters. It features large, velvety, bright green leaves with reddish undersides, and produces delicate pink or white flowers in late summer and early autumn. It's ideal for adding an exotic and long-lasting touch to shady gardens, woodland borders, or pots in sheltered patios.

Care tips
It prefers partial to full shade, avoiding direct midday sun which can scorch its leaves. Keep the soil consistently moist but well-drained during the growing season; reduce watering in winter when the plant goes dormant. Use a rich, organic, and well-draining soil mix. The most common mistake is overwatering in winter, which can lead to tuber rot.
