In cooler climates, suitable for use in sun or shade, must have shade in Texas. Needs a steady moisture supply, but not soggy soils. Tends to develop chlorosis on high pH soils. Not as vigorous as Vinca major.

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.
