Q.I Have Been Growing Peruvian Daffodils For The Last 3 Years. I Get Lots Of Great Foliage But I Have Never Had A Bloom On Any Of My
plants. The plants naturalize very well but never bloom. Why??? I have planted them the last 3 years in fertile, well drained soil, but never have any of the bloomed. They were also in a location for full sun exposure.

It sounds like your soil could be a little too nutritious! Too much nitrogen can cause poor, or lack of, flowering. Make sure to test your soil:

If all is in range, then you may need to grow them in container, so that they do not get disturbed during storage. This may help them take advantage of a longer growing period without change to the root zone, which ultimately, can help with flowering.
