The Premium Regional mixtures and the Value mixtures are our most popular choices in a wildflower mixture. In some cases, a special-use mixture can be a more suitable choice for your wild flower project. 

Each of the wildflower mixtures sold by Seedland contain a selection of species suitable for the specific usage.  The exact percentage ratio in the mix of each species is determined by the bloom time, soil types, climatic conditions, species type, aggressiveness, current availability, flower color, performance and cost.  The end result is a balanced wildflower mixture perfectly designed from the knowledge gained from over 20 years of actual field trial experience. 

*CUSTOMER NOTE:  All quotations & orders subject to seed availability. Mixture may vary occasionally from the indicated listing, based on availability of individual species.  All prices subject to change without notice.
