Hypericum calycinum aka Aaronsbeard St. Johns Wort

Hypericum calycinum, also known as Rose-of-Sharon, Aaron's beard, great St-John's wort, creeping St. John's wort, and Jerusalem star, is a prostrate or low-growing shrub in the Hypericaceae family. This evergreen plant, reaching heights of up to 30cm, spreads through runners and features arching, woody stems with slender, dark green leaves that have irregular, yellow-green margins. The new growth of the leaves has a bronze flush. In summer, Hypericum calycinum produces beautiful buttercup yellow flowers at the tips of its stems. Widely cultivated for its attractive appearance, this plant is commonly found in Mediterranean climates and is prevalent in the Strandja Mountains along the Bulgarian and Turkish Black Sea coast. As a houseplant, St. John's Wort, belonging to the Hypericum genus, is rare but easy to grow. It thrives with regular watering and prefers long-lasting, direct light within a foot of a window. Well-draining soil is ideal, and it usually doesn't require additional fertilizers if repotted when it doubles in size. This species is native to Southern Europe and Southwestern Asia.
