Intensia White Phlox

Intensia White is a compact annual phlox selected for bright white flowers and a long seasonal display. The exact selection code DPHLOX866 and patent references identify this plant on the current Proven Winners page, presented as Southern Blaze White III and noted as formerly part of the Intensia series. The source describes a low mounding habit, 10–16 inches high and wide, full sun, and flowering in spring, summer, and fall. It also notes heat and drought tolerance, butterfly attraction, and use in landscapes and containers. [Proven Winners’ Southern Blaze White III page](https://www.provenwinners.com/plants/phlox/southern-blaze-white-iii-phlox-drummondii) documents the selection and its growing traits. ## Growing Conditions Choose a sunny position with well-drained soil. The source recommends average water; containers need regular checks because they dry faster than garden beds. The compact mound suits edging, small groups, and mixed annual containers. ## Maintenance Water consistently during establishment and prolonged dry weather. The source reports that deadheading is not necessary, so routine removal of faded flowers is optional.
