The trumpet-shaped flowers display yellow to orange hues with the iconic black center, bringing a cheerful and bright touch to your garden.

Features and Benefits

• Annual climbing vine suitable for temperate and warm climates, ideal for trellises, pergolas, and planters.
• Showy trumpet-shaped flowers, with a distinctive black center that attracts attention and pollinators.
• Fast and vigorous growth, allowing it to quickly cover a support and create a floral wall effect.
• Prefers full sun and well-drained soil; tolerates hot and dry conditions once established.
• Abundant flowering all summer until the first frosts, with the possibility of rebloom after regular watering and deadheading.

Cultivation and Germination Tips

To optimize germination, sow seeds in a warm, bright environment. The soil should be kept slightly moist without being waterlogged. A soil temperature around 18–24 °C promotes rapid germination, usually in 7 to 14 days depending on conditions.

Transplant young plants after the last frost, placing them near a support where they can climb. Install a trellis, grid, or fence and guide the shoots to achieve dense floral coverage.

Water regularly during dry periods and be sure to avoid excess standing water. To prolong flowering, remove faded flowers (deadheading) and apply a light, balanced fertilizer during the active growth period.

Ideal Uses

• Planters and hanging baskets to bring a warm and bright touch to balconies and terraces.
• Decorative vines along walls, fences, and pergolas, creating a dynamic green curtain.
• Attraction points for pollinators: bees and butterflies appreciate the long corollas and regular blooms.
