Mother of Thousands

Kalanchoe daigremontiana

Mother of Thousands is a succulent perennial characterized by its prolific production of plantlets along the margins of its leaves. It features lance-shaped, fleshy leaves that are typically grey-green with purple blotches on the underside. These plantlets readily detach and root, leading to rapid spread. While primarily grown outdoors in warm climates, it's sometimes kept as a houseplant for its unique appearance and ease of propagation. However, its invasive potential and toxicity should be carefully considered. It is not naturally an indoor plant and requires specific conditions to thrive indoors.
