Answer: I think you might have seen Buddleja x weyeriana 'Bicolor.' It has orange and raspberry pink blooms. Your local nurseries may have it, for contact information you could use the zip code based dealer locator at
They are independent retailers and each carries its own selection of plants and I have no way to check for you which nurseries would have certain plants in stock on hand or expect to have them later in the season.
If it is not available locally, you might try mail order. Bicolor is listed in the current Wayside Gardens catalog, for example.
Best of luck with your search!
