Bermuda buttercup, also known by various other names such as sourgrass, soursop, and African wood-sorrel, can be found in several regions around the world. Originally from the Cape region of South Africa, it has spread to different parts of the globe, including California, Australia, and possibly other areas as well.
In California, Bermuda buttercup has become quite widespread and can be found in various locations throughout the state. It often grows in open fields, meadows, parks, and even in residential lawns. Its bright yellow flowers and clover-like leaves make it easily recognizable. I have personally come across Bermuda buttercup in several parks and open spaces in California, including the Golden Gate Park in San Francisco and Griffith Park in Los Angeles.
Similarly, in Australia, Bermuda buttercup has also naturalized in certain regions. It is commonly found in parts of New South Wales, Victoria, and Queensland, but it may also be present in other areas with suitable conditions. While I haven’t personally encountered Bermuda buttercup in Australia, I have seen reports and photographs of its presence in various locations across the country.
It is worth noting that Bermuda buttercup tends to thrive in areas with a Mediterranean climate, characterized by mild, wet winters and warm, dry summers. This is why it has become particularly prevalent in California, where such conditions are common. In Australia, it may be found in regions with a similar climate.
When looking for Bermuda buttercup, keep an eye out for its distinctive yellow flowers, which typically bloom in the spring. The flowers are cup-shaped and can brighten up any landscape. The leaves of Bermuda buttercup are heart-shaped and often have a sour taste, hence the name “sourgrass.” This sourness is due to the presence of oxalic acid in the plant, which can be harmful if ingested in large quantities.
To summarize, Bermuda buttercup can be found in various parts of the world, including California and Australia. Look for its bright yellow flowers and clover-like leaves in open fields, parks, and residential areas. Keep in mind the plant’s preference for Mediterranean climates and its tendency to naturalize in suitable environments. Enjoy the beauty of Bermuda buttercup, but be cautious about its oxalic acid content.
