Blooms in red, yellow and blue stole the show at this year’s California Spring Trials. Here are some of our team’s favorites to keep your store on-trend into 2026.

Blue Is the New Bold

True-blue flowers are one of the many difficult breeding qualities to achieve. I have seen blues in person that range from light periwinkle to dark royal blue. Sometimes my eye sees more purple or red, and when I do see one of those true-blue varieties, it feels impossible to capture in a photo.

Here are a variety of new blues that are sure to astound in person — and maybe on camera, too!

Benary: Viola ‘High Flyer Blue Heaven’

High Flyer pansies have a mounding, globe-shaped habit — great for hanging baskets. This day-length-neutral plant has long-lasting flowers and will also bloom during shorter days below 8 hours of sunlight.
