It is also necessary to address the dual nature of the vine during its peak season. As the flowers are pollinated, they give way to long, bean-like seed pods that add a textural element to the plant through winter. Yet, the vigor that allows for such a stunning floral display also makes the plant aggressive. Gardeners must manage the vine through pruning immediately after the flowering season to prevent it from overtaking structures or choking out neighboring plants. The very tenacity that allows the vine to bloom through the heat of August also makes it a potential nuisance if left unchecked.
In warmer southern climates (USDA Zones 7–10), the season may start as early as late May. In cooler northern regions (Zones 4–6), you might not see the first orange "trumpet" until July.
The orange trumpet vine is a summer standout. In most temperate climates, the flowering season typically spans from (roughly June through September).
The Orange Trumpet Vine (often called Flame Vine or Cana-de-Macaco ) is a show-stopping climber, but its is what truly separates it from other garden plants. Here is my honest review based on three growing cycles.
If you want a wall of orange that lasts for months, follow these maintenance tips: 1. Prune in Late Winter
Since the vine blooms on new wood, the best time to prune is late winter or very early spring while the plant is still dormant. Cutting it back aggressively not only keeps this "vigorous" (and sometimes invasive) grower in check but also stimulates the fresh growth that carries the summer’s flowers. 2. Avoid High-Nitrogen Fertilizers
