Summary

Hypericum linariifolium, commonly known as Toadflax-Leaf St. John’s-Wort, is a deciduous shrub native to open woodlands, scrubby areas, and rocky hillsides in Southern and Western Europe. It typically grows at a moderate rate to a height and width of 1.5-3 feet (0.46-0.9 meters). The plant features narrow, linear leaves and bears bright yellow, showy flowers from summer to fall, which are particularly attractive to a variety of pollinators. The flowers are followed by reddish-brown, capsule-like fruits that add interest to the winter garden.

Toadflax-Leaf St. John’s-Wort is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for rock gardens, xeriscaping, and as a ground cover in challenging conditions. It is also used in borders and as a low hedge. This species is resistant to many pests and diseases, but can be susceptible to root rot in poorly drained soils. It is important to note that while it is not invasive, it can self-seed and spread in the garden if conditions are favorable. Toadflax-Leaf St. John’s-Wort requires minimal maintenance, making it a suitable plant for gardeners seeking low-care landscaping options.CC BY-SA 4.0
