Power Couple - Poppy & Delphinium Flower Seed Mix

Very upset!!

I'm a new gardener. I was so excited to do a garden in a section near our front door for everyone to see! I bought a rototiller. Used that and a shovel to get all debris and Dandelion roots dug up. After my dirt was prepped, I checked the ph in my soil. I finally planted the seeds and waited. I waited to find a bunch of grass and a few dandelions throughout the entire garden bed. This mixture is garbage!!! So much grass and weeds, I'll have to start from scratch next year with seeds I'll buy elsewhere. I did use the Partial Shade Wildflower Seed Mix on a planter attached to the outside of the house. It's right next to this messed up bed, but about 3 feet higher off the ground. I am including a picture of me clearing the bed. I thought I had a picture when the bed was ready for seeding, but can't find it, so I could show everything was cleared out. So, disappointed spending all the time and money.

Disappointed

I had a vision of red and purple wildflowers, like I see on scenic NC highways in my area. The poppies bloomed at least a month before the delphinium. The poppies were sparse and had died before the purple bloomed. I live in Asheville NC and they are in full sun. The photos showed them blooming together.
