Dümmen Orange showcases varieties rooted in science and art at CAST 2026
Dümmen Orange brought the art of science and the science of art to life at California Spring Trials (CAST).
Across annuals, perennials and combination programs, the 2027 lineup delivers innovation, flexibility and reliable performance for growers and retailers.
In annuals, the I’Conia begonias subseries has simplified program building while delivering consistent performance. New for 2027, ‘I’Conia Valencia Pink’ offers standout color, strong branching, excellent heat tolerance and versatility across multiple pot sizes.
The dahlia Summer Bees line has expanded with Salmon Bicolor and Red Star. Dahlia Summer Bees have bold color, strong branching and a pollinator-friendly upright habit. In petunias, Sweetunia Violet Vortex stands out with a medium upright habit, early flowering and a striking tricolor pattern. Sweetunia Violet Vortex is also powered by Intrinsa for reliable, disease-resistant production.
Additional new highlights include New Guinea impatiens Petticoat Neon Flame, Lilac Ice and Orange, which offer a medium-compact habit and early, uniform flowering which makes it ideal for small pots and baskets, and coleus Down Town Santa Fe, the most compact series in the lineup, now feature a rich burnt orange that shines in sun and glows in shade.
For season extension, lantana Havana delivers with improved performance and a bold new Cherry Red, ideal for late spring through early summer sales.
Dümmen Orange also displayed purpose-driven combinations designed for efficiency and impact. The new Garden Party Shade Princess series answers demand for premium shade solutions by pairing New Guinea impatiens with bold foliage from the Welcome to the Jungle line. BlooMix blends first-year flowering perennials with cold-tolerant annuals to create dynamic combinations that extend color at retail and in the landscape.
True North Perennials varieties are rigorously trialed to survive two winters 200 miles north of Fargo, North Dakota, to deliver reliable Zone 3 hardiness. From standout performers like leucanthemum Sweet Daisy Kylie to dianthus Mad Magenta and the addition of the veronica Candela series, the portfolio offers dependable performance.
At the core of the perennial program is the First-Year Flowering collection. This provides vibrant retail color and unmatched production flexibility without the need for vernalization, which makes it ideal for both northern and southern markets.
One of the new standouts among the first-year flowering varieties was agastache ‘Honeysticks Gold’, which adds a vibrant new dimension to the Honeysticks series with its compact habit, strong branching and reliable Zone 4 hardiness. It is an excellent choice for both production efficiency and landscape performance.
At the end of CAST 2026, Dümmen Orange donated all of its plant material for the fifth year to the Tolosa Children’s Dental Center (TCDC), which held a plant sale fundraiser. The sale raised around $15,000 for the nonprofit based in Paso Robles, California, which opened in 2003 to help underserved and underinsured children access quality, consistent oral health care.
As the only nonprofit pediatric dental center in San Luis Obispo County, TCDC remains committed to ensuring that every child, regardless of income, has access to essential oral care.
