2020 Caladium Trials at the Cincinnati Zoo & Botanical Garden
We all want to forget 2020 and move on from its tumultuous tendrils. But let’s focus on the positives. It is also a year of dogged perseverance, boundless creativity and discovering endless outdoor activities. Since gardening and horticulture encompass these things, and as we eagerly look to the 2021 growing season, we also look back at gardening successes from the previous year.
2020 was our year to trial new Caladiums. Why Caladiums? Well, besides being one of the most beautiful foliage annuals for shade, they are also becoming more versatile. This year we trialed Caladiums from Classic Caladiums and Proven Winners. We discovered these new Caladiums can take more sun and a few varieties even seem hardier – some lasting to October 1st! Let’s look at a few of our favorites, and since it is winter, we will start with one that should inspire some warmth.
Our Hardiest, Top Picks
Caladium HEART TO HEART Caribbean Coral was voted one of the top ten Zoo’s Best plants! It sported a rare and beautiful coral pink color. It was planted in part shade and performed strong and healthy until the end of September.
Beauty and Brawn
It is usually recommended that caladiums are taken inside before the evening weather turns to a consistent 40F degrees. Wherein many of the caladiums were beginning to give in to the cooler season, these beauties were looking fantastic after at least two or more 40-degree nights:






Top Picks for Small Gardens
The next selection of Caladiums was smaller, either in stature or breadth, and would do well planted in a container or massed in a small garden. These varieties were the best, most consistent little gems displaying from mid-May to late August/early September.





Big and Beautiful color mid-May through mid-September
Considered top picks in my book and definitely in the running for Zoo’s Best, these beauties didn’t last quite as long as the first list of selections, but definitely gave them a run for their Lamina (leaf blades) until mid-September!
