Origin & Breeding History: 'USPHLO322' is the product of a planned breeding program with the objectives to create new vigorous Phlox varieties that are heat tolerant and have a long flowering period. 'USPHLO322' originated from a controlled cross conducted in Hikone, Japan on March 29, 2001, with a seed raised Phlox drummondii variety with magenta flowers as the female parent and a wild Phlox sp. as the male parent. The new phlox was selected as a single plant from the resultant progeny on May 24, 2002. Selection criteria included strong plant vigour, tolerance to heat, long flowering period and low seed set.
Tests & Trials: Tests and trials were conducted in a polyhouse during the spring of 2006 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference variety. Observations and measurements were taken from 10 plants. All colour measurements were made using RHS colour chart 2001.
