Description

Thunbergia erecta, also known as Bush Clock Vine or King’s Clock Vine, is a stunning tropical shrub that adds both beauty and color to gardens and landscapes. Known for its striking, large, funnel-shaped flowers in shades of deep blue to purple, this plant creates a bold, eye-catching display. The flowers are complemented by lush, dark green foliage that provides a perfect backdrop. Thunbergia erecta can grow as a bush or be trained to climb, making it a versatile addition to your garden. It’s perfect for adding vertical interest to trellises, fences, or arbors, and it’s also ideal for hedges or mass plantings.

Light requirements

Thunbergia erecta thrives in full sun to partial shade. For the best flowering and robust growth, aim for at least 4-6 hours of direct sunlight each day. While it can tolerate some light shade, it will flower more abundantly and grow more vigorously in full sun. A sunny spot encourages lush foliage and vibrant flowers, making it a great choice for bright garden areas.

Soil preferences, including pH and drainage

This plant prefers well-draining, slightly acidic to neutral soil, with a pH range of 6.0 to 7.0. It does well in a variety of soil types, including loamy or sandy soils, as long as they allow excess water to drain easily. Good drainage is crucial to prevent root rot, so make sure the soil is well-aerated. If growing in containers, use a potting mix designed for tropical plants and ensure the container has adequate drainage.

Water needs

Water Thunbergia erecta regularly, keeping the soil consistently moist but not soggy. It enjoys regular watering, especially during the growing season, but it dislikes being waterlogged. Ensure the soil dries out slightly between waterings to avoid root rot. During the cooler months, reduce watering, but still make sure the plant doesn’t dry out completely. A moderate, consistent moisture level is key to keeping this vine healthy and vibrant.
