Additional Comments:

Appears to tolerate hot humid conditions better an most Cotoneasters. Drip irrigation is better than overhead with Cotoneasters. Needs a steady moisture supply, but also a very well drained soil.

A Special Note about Cool Season Annuals

Cool season annuals typically are planted in the fall or early winter and flower in early spring under moderate temperatures. This group of plant materials includes: pansies, snapdragons, violas, dianthus, flowering cabbage/kale, etc. Because cool season annuals flower in the spring when conditions are mild, most have limited heat tolerance.

As a result cool season annuals do not receive a high Earth–Kind® index despite their outstanding landscape qualities.
