2023 IWGS New Waterlily Competition
This year, to ensure the best conditions for all categories of waterlilies, we opted to have 2 different growing locations for the submissions. The hardy and hardy ISG waterlilies were grown in a more temperate site at Longwood Gardens with growers Suzanne Boom and Tim Jennings, while the tropical waterlily categories continued to be grown out at Naples Botanical Garden, with grower Matthew Herrman.
We received entries in each of the following 5 categories: Hardy, Tropical Day-Blooming, Hardy Intersubgeneric, Tropical Intersubgeneric, and Tropical Night-Blooming Waterlily.
The entries were evaluated by an international panel of judges on the quality of the flowers and foliage as well as the general impression and uniqueness of the plant. These evaluations were made based on the grower’s notes and photos over the eight-week observation period. Among the judges were professional waterlily growers from botanic gardens and plant nurseries, as well as hybridizers and experienced hobbyists.
