Abstrakt: The article discusses a study on how to get Veronica Red Fox and Veronica Christy to flower. The Veronica Red Fox blooms for about four to five weeks in May or June and remain vegetative indefinitely. It is a plant that requires an absolute treatment for cold before it will flower and it vernalizes most rapidly at 28°Fahrenheit. The Veronica Christy flowers in less than three weeks at 68°Fahrenheit under 9- or 16- hour photo-periods following vernalization.
