Castle Rock Blooms
“Happiness held is the seed,
Happiness shared is the flower”
John Hurrican
Our 2026 Plantings
Each season, Castle Rock Blooms volunteers plant dozens of colorful pots and containers throughout our town — from the Riverfront Trail to Front Avenue. Scroll down to explore every plant featured in 2026, learn about each one, and discover how to grow them in your own home.
Superbena® Whiteout™
Bright Lights Pink Annual
Superbena verbenas are very vigorous with strongly trailing habits. They need relatively long days to bloom and are difficult to produce in small container sizes. They have very large flowers and umbels. These white verbena plants are great in landscapes and containers. In landscapes, they are best used at the front of beds and they function as spillers in combination planters. If you are looking for a colorful annual ground cover, Superbena Whiteout verbena is a great choice.
A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Stardiva® Blue fan flower
Meet the first-ever series of Scaevola aemula with star-shaped rather than fan-shaped flowers. Though both types have five petals, those of the new Stardiva® series are arranged in a perfect star formation, lending a larger, fuller appearance to the blossoms. Pollinating bees are quick to find the tiny white bullseye that rims the throat of each violet blue flower. These plants form a compact, densely mounded to semi-trailing mound that is smaller overall than Whirlwind® Scaevola. They are extremely durable in sun, heat, humidity, rain, drought and wind. Color doesn’t get any easier than Stardiva!

ColorBlaze® Mini Me™ Chartreuse
Coleusscutellarioides
This wonderful new ColorBlaze Mini Me Watermelon coleus for sun and shade features watermelon to coral foliage with golden chartruese accents, forming a very well-branched watermelon coleus plant that works well in landscapes and containers. Like all ColorBlaze® Coleus, this heat tolerant coleus is bred to take the heat and bloom very late in the season, if at all, extending its garden performance into the fall as a reliable watermelon coleus. This is a new type of ColorBlaze coleus that is substantially smaller than the rest of the ColorBlaze coleus.
Though we select for stable color patterns, occasionally ColorBlaze Mini Me Watermelon coleus will have variable leaves or branches. Most often, the color change will show up as a dark burgundy leaf or branch. In very rare instances, the entire heat tolerant coleus plant will display the variable color. It is not harmful to the plant in any way. If you like it, simply leave it be. If not, trim off the part of the plant showing the color change. We are working to eliminate this variability in future and appreciate your understanding. Adaptable As Houseplant

Loads of flowers on a tiny plant!
This dwarf panicle hydrangea will turn heads! Bobo® hydrangea is engulfed by large white flowers in summer. The flowers are held upright on strong stems, and continue to grow and lengthen as they bloom. No flopping, unlike some panicle hydrangeas! As blooms age, they turn pink.
It is compact and dwarf in habit, and the flowers cover every inch of the plant right down to the ground. This plant was developed by Johan Van Huylenbroeck, the same breeder that developed Pinky Winky® hydrangea.
