I love seeing that even so-called old-fashioned plants such as perennial phlox still attract breeders’ attention and they invest time and energy in crossbreeding and selecting new, hardier, healthier, and more beautiful varieties. Their popularity is proved by the fact that they occupy 3 large pages in the RHS Encyclopedia of Plants (not many plants can boast that).
Description of the plant:
Exquisite is what this perennial phlox truly is. It is called YOUNIQUE OLD BLUE and it was bred by Janus Verschoor from a renowned Dutch perennial nursery A. Verschoor Horticulture. It boasts rather large, 3-4 cm across, fragrant flowers in an adorable pastel lavender blue shade with a white windmill-like mark in the centre. They are composed in terminal, rounded panicles over an extremely long period from June until October. Haven’t you fallen in love yet? Keep reading then.It is a shorter growing variety, not dwarf, quite compact, commonly reaching about 40-50 cm in height, possibly a little taller in humus-rich, moist soils. Leaves are broadly elliptic, 8-9 cm long, 3-4 cm wide, dark green, partially glossy, and significantly resistant to powdery mildew. In other words when other perennials may exhibit exhaustion or late summer diseases from September onwards, YOUNIQUE OLD BLUE phlox stands still and healthy like a pale lavender beacon till the very end of the growing season. It was granted a US plant patent No. PP26070 in 2015.
Growing phlox is easy. It likes almost any garden soil, fertile or poor, but with enough nutrients the flowering will be heavier, and the plant will not suffer common phlox diseases. They are long-lived plants that will stay in your garden until you dig them out. Sunny location is preferred but will flower in partial shade, too. Hardy to about -34°C (USDA zone 4).
