Double Wave® Purple - Petunia

Double Wave® Purple is the trade name recorded for the petunia cultivar Kirimaji Double Purple. Its U.S. patent describes low mounding growth that cascades to a prostrate form, with freely branching stems and richly colored, ruffled flowers; the Canadian variety record also identifies it as a purple double petunia.

Its source-described purple blooms are distinctive in mixed plantings, and the patent reports early, continuous flowering from spring until autumn frost. The patent also records a faint sweet, floral fragrance. ## Growing conditions Petunias grow best in full sun and moist, well-drained soil. Choose a potting mix that drains freely and keep containers from standing in water. [Illinois Extension](https://extension.illinois.edu/flowers/petunia) ## Maintenance Check pots regularly and water when the mix begins to dry, since containers can dry faster than garden beds. Remove spent flowers to keep the plant neat, and trim stems selectively if they extend beyond the intended container shape. Its patent describes the cultivar as freely branching and notes that pinching is typically not required; no particular hardiness zone is stated in the cited selection records.
