Success will be determined by how fertile the ground is and quality of the seeds you purchase. I did a Zenia garden on our drain field one year and it did great. Tried the same thing in the front yard and it didn't do squat. Part of the front yard problem was the seeds I bought from Home Depot not actually being Zenias as pictured on the pack. I did follow up with the same brand I used on the drain field and the yellow daisies I got from HD seemed to proliferate and choke them out.
