Allamanda is a bushy, twining vine with vividly coloured funnel or trumpet-shaped blooms and thick foliage.
Allamanda grows thickly as a shrub and blooms in the summer with yellow bell-shaped blooms that are 3 to 4 inches long. Although it lacks tendrils for climbing, it can grow like a vine with the right support.
Allamanda is a natural bushy shrub. Because the plant grows heavier with time, it is best to use a large container. It’s possible that you’ll have to repot it every year. Make sure the container has drainage holes at the bottom, regardless of size, to ensure that water drains smoothly. Fill the holes with stone or bricks.
Even in poor soil, the woody vine grows vigorously in full sun or semi-shade. Because the plant climbs and develops quickly, it’s ideal for covering pergolas or other structures with horizontal support.
