Dümmen Orange presents: California Spring Trials 2025 Highlights!

It’s hard to believe it’s already been over a week since California Spring Trials (CAST) wrapped up in California for us!

This year marked a special milestone—our 25th Anniversary in North America, and we’re so grateful for our customer and industry friends who stopped by to celebrate with us!

We had a fantastic time showcasing our latest varieties and series—from the buzzworthy new Dahlia Summer Bees to our stunning I'Conia^® hybrid begonias, eye-catching Confetti Garden^® combinations, and our expanded La Diva Lavender Collection featuring five new introductions.
