Merremia tuberosa (Large Woodrose) is a climber native to Asia, although it can be found across warmer regions of the world. With tuberous roots and five to seven narrow lobed, glabrous leaves, it is highly distinguishable. The flowers are a vibrant, deep yellow color, with five petal-like sepals that appear after the flower finishes blooming. The large woodrose is a favorite among gardeners for its bright flowers, which also attract butterflies and hummingbird.
The plant is only known to thrive in USDA Zone 9-11. It prefers full sun exposure and moderate water requirements, while also being able to tolerate some semi-shade. This makes it ideal for home gardens and those with limited outdoor space. If you live in a colder climate, the best way to grow this plant is in a pot, as the roots need to be kept moist and warm.
The Large Woodrose can be invasive, so make sure that you monitor it carefully and practice regular pruning and trimming.
With the right care and attention, the Large Woodrose can be a stunning addition to your garden, adding a splash of color with its yellow, orange flowers and its attractive vines. If you are looking for an eye-catching, low-maintenance plant, Merremia tuberosa may be the perfect choice for you.
