Answer: The Flower Carpet series should be widely available nationwide from many different nurseries and suppliers, so perhaps you are looking for it too early in the season or they have already sold out locally. Keep in mind many nurseries stock a wider variety of roses for Mother's Day and when the roses are in bloom.
Unfortunately I have no way to check on what the different stores may have ordered or plan on ordering. They are independent retailers and each stocks its own selection of plants. Perhaps if you spoke with the individual store managers they could tell you if they expect to have it and possibly reserve some for you.
Otherwise, you might try mail order. The Tesselaar web site (Tennselaar introduced this plant) includes a source for that. You may need to cut and paste the complete url to make it work correctly.
I'm sorry you are having trouble finding NOAtraum. It's a great rose.
