This is the garden center flower that has white flowers, sold in hummingbird mix. Flowers are fragrant at beginning and end of day but not middle. There are several inchworm caterpillars eating the plant. Some have dark heads and legs, others have green but otherwise they look similar. It is apparently a host plant for whatever these caterpillars become.
