Evening Primrose?

These will do well in hardiness zones 7-9. If you are outside of these limits, then I would consider keeping them as inside plants.

As far as deer resistance... Even if it is deer resistant... I have learned, that deer will eat anything, unfortunately.

Here is an article on the primrose: https://www.gardeningknowhow.com/ornamental/flowers/primrose/growing-primrose-primrose-plants-in-your-garden.htm

There are several evening primrose species. I think you are talking about Oenothera speciosa. You are encountering the result of these pretty plants setting lots of seed. You pull the plants only to have more seeds germinate. If you keep up, you will exhaust the "seed bank", the dormant seeds in the soil that are patiently waiting for the right conditions to germinate. Hoeing will kill the plants. You might consider a pre-emergent like Preen after removing all seedlings. A 4 inch layer of mulch may also work.

Oenothera biennis, aka common evening primrose is a biennial which means it lives for 2 years then dies. The first year it forms a basal rosette of leaves and no flowers. The second year, it sends up the flower spike(s) and sets seed. To keep it in the garden, it is necessary to collect seed or allow the plant to self-sow. Cut the flower stalk down or remove the plant. It will not come back next year.

Here is info on pink and yellow evening primrose.
