Hello
My name is Martyn and I have been growing succulents for many years. 
Recently I have sown quite a few Echeveria species from Gerrard Koehres seeds.
This year I have flowered what I believe to be Echeveria trianthina and Echeveria rodolfii.
They are two lovely plants and I am hopefull that they are good species but second or third opinions are welcome.
I do have resonable photos if they can be of use here.
Unfortunately both batches of seed germinated poorly and I got one plant of each specie!
Please take a look and see what you think of them
