Originating from diverse regions worldwide, these shadowy beauties adapt to various climates, showcasing the stunning diversity of plant life.

If you’re curious about the darker side of botany, exploring these almost-black blooms is a fascinating way to dive deeper into gardening’s unusual palette.
