Rudbeckia ‘Sunbeckia Ophelia’

Best of Show – Rudbeckia ‘Sunbeckia Ophelia (Flamingo Holland). Gigantic yellow flowers attracted attention from across the garden. The huge flowers create a near solid canopy of yellow color that creates enormous flower power. Foliage that is visible is very attractive and clean. Plants require no pinching and matures at a nice medium height. The long-lasting flowers keep a fresh look and stay low maintenance by “burying its dead.” Performance was excellent both in ground and containers.

Best Novelty – Heliotropium ‘Augusta Lavender (Proven Winners). Prolific flowering was sustained throughout the entire growing season. The soft lavender flowers were very showy and had a slight fragrance in the heat of the afternoon. Plants had good uniformity and were a favorite of pollinators.

Best New Variety – Bidens ‘Brazen Imperial Luck’ (Syngenta Flowers). The vigorous plants were densely branched and created a solid mound of flowers across the canopy which created an impressive display of color. Blooms maintained a uniform pattern and had a rich saturated red color that paired well with the dark green foliage.  This entry was also very popular among the bees.
