Seed production of Nepeta grandiflora M. Bieb. and N. sibirica L. (Lamiaceae) during introduction to the Perm region

We studied seed production of Nepeta grandiflora M. Bieb. and N. sibirica L. introduced to the Perm region. Seed production is one of the most important features during plant introduction. Perennial studies of seed production of gynodioecic N. grandiflora showed the diversity of this feature in different sexual forms, depending on weather conditions and insect-pollinators activity. Both studied species have a stabile seed reproduction and ability to vegetative reproduction, sufficient winter hardiness, long flowering period and resistance to the pests and diseases. These plants should be highly estimated and can be recommended as perspective decorative plants for Perm region.
