St. John’s Wort (Hypericum Calycinum) are known for their bright yellow flowers, similar to ‘sunbursts’ of color. They can be trees, shrubs, annuals, perennials, evergreen, or deciduous. The blooms themselves are small, but there are tons of them nestled among rich green leaves, and can be used as groundcover. They grow about 1 to 3 feet tall and wide, and have an upright growing habit, and prefer rich well-drained soil type.
They prefer full sun or part shade, are low maintenance, and are even deer resistant, making them a great piece for landscaping. They flower during June until fall, and then have attractive colorful berries. They adapt well to both moist and dry soil, and can withstand drought conditions – they are very hardy.
