Hypericum androsaemum, also referred to as Tutsan, Shrubby St. John's Wort, or sweet-amber, is a flowering plant in the family Hypericaceae. It is a perennial shrub reaching up to 70 cm in height, native to open woods and hillsides in Eurasia.
Tutsan is the larger flowered variety of Hypericum, or St. John’s Wort. It is native to western and southern Europe and from the Mediterranean to Iran. It was a common medicinal plant. Regional gardeners were growing Tutsan shrubs to make tinctures that cured all sorts of ills. Today, it is a spectacular deciduous flowering shrub that makes its best showing in June to August with large attractive berries following into September.
Like most plants, hypericum does not like to sit in wet soil. Overwatering can cause the roots to rot. Allow the soil to almost dry out between watering.
The plant prefers shady to semi-shaded locations that mimic its natural positioning at the base of woods but can also thrive in sun.
Hypericum grows in most soil types but has a preference for soil with a pH of between 5.5 and 7. It does not like waterlogged soil.
The plant may lose some leaves at temperatures below -3°F but will not suffer any long-term damage and will be perfectly fine up to at least -14°F.
