PHS Headquarters Plant List: Spring 2019

Ever wonder what is planted in front of PHS? This subject guide will provide information on the plants currently planted in and around PHS. PHS Project Manager Sam Keitch designs and plant these attractive displays.

Acorus ‘Ogon’

Easily grown in average, medium to wet soils in full sun to part shade. Plants perform well in both boggy conditions (including shallow standing water to 3-4” deep) and consistently moist garden soils. Never allow soils to dry out. Scorched leaf tips and withering leaves are often the first signs of drying soils.

Amelanchier x. ‘Autumn Brilliance’

‘Autumn Brilliance’ serviceberries (Amelanchier x grandflora) are a cross between A. canadensis and A. laevis. Its genus name stems from the French provincial name for Amelanchier ovalis, a European plant in this genus and, of course, its cultivar name is reminiscent of its brilliant orange/red fall hues. It is hardy in USDA zones 4-9.
