About Allamanda cathartica

Standing tall at 6 to 20 feet in height and spreading out to a width of 3 to 6 feet, the Allamanda Cathartica is no wallflower. Its leaves are a rich emerald color, providing a stunning contrast to the canary-yellow flowers that bloom in late and peak seasons. One thing to note, this plant does not produce any fruits.

Despite its tropical appearance, the Allamanda Cathartica is surprisingly hardy and can be used as a hedging plant. It's also a trailing plant, meaning it can be trained to grow along walls or trellises for a truly spectacular display.

Edibility

While the Allamanda Cathartica is a feast for the eyes, it's not one for the stomach. This plant is classified as a venomous flora, so it's best to admire its beauty from a distance and not include it in your salad!

Our design recommendations

The Allamanda Cathartica is a model plant for adding a pop of color to any garden. Its eye-catching flowers and lush foliage make it an excellent choice for cluster planting. It can also be grown in a tub as a domestic plant, bringing a touch of the tropics to your home. Given its size and trailing nature, the Allamanda Cathartica is best suited for larger gardens. However, it can also be grown in tubs or containers, making it a versatile addition to any landscape.
