I had a similar experience with the picotee blue.
I had a different m.glory bloom.
It was very pretty!.Here is a photo from the seed I grew out.

I had that happen years ago with osteospermum seeds I bought from a large national seed company. The variety was supposed to be 'Passion Mix', mainly purples and pinks and cool colors; instead every plant bloomed the same screaming orange color. I could have bought that color of osteospermum seeds almost anywhere quite cheaply but instead had gone the mail order route, paid much more for the seeds plus shipping and handling, so was really disappointed at the results.

I contacted the seed company and explained the situation. They replaced the seeds and once again the result was screaming orange flowers. I contacted them again and they told me they only replaced seeds that did not germinate once; I explained that it wasn't lack of germination, but that the colors were not what had been stated, and asked for a refund. The company never responded.

Seed companies buy their seeds from lots of different growers, many of them overseas, and sometimes there are mistakes. I think the company that actually sells the seeds to the public should be responsible and make good when the product is not what it was described as being, so I was very disappointed that the big-name company I dealt with refused to do so.
