Summary
Trachelium caeruleum, commonly known as Blue Throatwort, is an evergreen or semi-deciduous perennial herb, native to the Mediterranean Region, specifically found in habitats such as coastal scrub, open woodlands, and meadows. It can grow up to 120 cm (47 in) tall and 30 cm (12 in) wide. This woody-based herbaceous perennial features oval leaves and produces dense cushions of violet-purple flowers in the summer, which are highly attractive to pollinators. The flowers are showy and make for excellent cut flowers as well.
Blue Throatwort is valued for its long flowering period and vibrant flower colors, which, along with its tolerance for drought once established, make it a popular choice for summer bedding schemes, planters, and as a border plant in temperate climates. It has been recognized with the Royal Horticultural Society’s Award of Garden Merit, indicating its reliable performance in gardens. Cultivars offer a range of flower colors, including white, red, pink, and dark purple. For optimal growth, it requires full sun to part shade, consistent moisture, and well-drained soil. While it is generally easy to maintain, it can be susceptible to snails and slugs, and in colder climates, it may need protection from frost.CC BY-SA 4.0
