Abstract

Gypsophila paniculata L., a dicotyledonous, herbaceous member of the Caryophyllaceae, was introduced into North America from Eurasia as a garden ornamental and has escaped to become troublesome in some areas. A life history study has revealed that this species is spread entirely by seed, its tumbleweed character being an important factor. Germination occurs mainly in the spring in Saskatchewan stands, perhaps as a result of no dormancy in the seeds. Although seedling development is characterized by a rapid penetration of the root system, mortality in natural stands is high. Under favorable conditions, at least 2 yr are required for the production of floral primordia. The mature plant is characterized by a root system which penetrates to depths of 4 meters or more. Shoots arise each year from a thick woody caudex.
