Perennial Plant of the Year 2002
Zone 3 - 9
'David' is a gorgeous summer phlox, with very large, clear white, flower heads, blooming from July to September. This 3-4' phlox forms a sizeable clump over time and has a very upright form. Unlike many varieties of summer phlox, 'David' has excellent mildew resistance and is also quite fragrant. Grow this exceptional phlox, in sun to partial shade, in rich humus soil. It prefers an evenly moist, but not soggy, location, and benefits from the application of a natural fertilizer, such as bonemeal and well rotted manure. Having said that, this plant is also very tolerant of less than idea conditions and will tolerate drier conditions. HEIGHT: 100-120 cm SPREAD: 100-120 cm
