Hypericum patulum ‘Hidcote’ – This wonder shrubby St. Johnswort sports showy 2” golden-yellow flowers with a beautiful plush set of stamens in summer at the tips of new wood. The almost diamond-shaped leaves with rounded corners are simple, opposite, medium glaucous green above and whitish below. Most autumns the foliage turns yellow but as I describe it this year on October 28, 2009, the leaves are aglow in a beautiful light bright orange with some deeper highlights – very nice! We cut ours down to the ground annually and depending upon spring to early summer moisture it will grow between 2.5’ to 4’ tall. This is an easy, tough and handsome shrub in well-drained soil and sun – virtually evergreen in climates warmer than our own. ‘Hidcote’ is still underused and we can’t understand why? For gardeners towards the northern end of its range spring planting is advised. Established potted St John's Wort, cutting grown.
St. Johnswort is easy, tough and dependable – they should be planted more! All have attractive sunny golden-yellow flowers, appreciate siting in full sun and planted in any decent garden soil that drains well, sandy soils are fine. They are untroubled in the north but apparently, according to Michael Dirr, they can be plagued farther south – where the cutoff is we do not know; we’re guessing the warm end of USDA zone 7. They are relatively underutilized and worthy of consideration if you live in a climate in which they will make you smile. All of the following offerings are cutting grown.
