‘Designer Jewel’ is a medium size kohleria, with relatively large flowers and leaves. This is a beautiful hybrid by Alfredo Lin.
The leaves are light gray and marbled, making this hybrid really stand out. It’s the only hybrid I have with that coloration of the leaves.
The flowers are relatively large too, showy, and appear clustered at the top of the plant. Despite the large leaves and flowers, the plant doesn’t grow very tall.
It’s definitely a showy, generous bloomer, but more of a seasonal one, in my experience.
