Mast Young Plants Fall 2026 Mum & Aster Catalog
Introducing Mast Young Plants’ Fall 2026 Mum & Aster Catalog. This is your complete guide to our full lineup of mums, asters, and popular accent varieties for creating vibrant summer combinations.
The catalog is organized by color and response time, making it easy to find your favorite mum colors and plan production by bloom timing — early, mid, or late season.
Don’t miss our Hardy Mum feature on page 16, highlighting the fully hardy Igloo series. We’ve included our top sellers and photos from our in-house trial verifying their week-37 bloom time.
Pages 17–20 showcase our summer companion plants. These varieties thrive in the summer heat and continue performing beautifully into fall. New for 2026, we’re excited to introduce the SunMagic® Echinacea series, which stood out in summer trials and is sure to be a retail favorite!
