I would love to plant the seed. Sending you an email. heirloomer08

Dame's Rocket (Hesperis matronalis) is an introduced species native to Eurasia. It does best in moist, well drained soil. It does better in cooler climates and is considered invasive in Massachusetts, Conneticut, Tennessee, Colorado, Minnesota, Nebraska and Wisconsin. It is often used in "wildflower" mixes because it grows so easily. It's prolific seed production is what makes it invasive. Texas heat limits flowering and seed production. Drought limits its germination and growth. As you noted, we had a lot of rain in November. If you lived in northeast Texas you might receive enough rain to allow this plant to spread. As you live in San Antonio it is likely to be too hot and/or dry for the plant to become invasive. As long as people keep this plant in their flower beds and borders it can be enjoyed without guilt. If you ever decide to use a wildflower mix I recommend Native American Seed Co. as their mixes contain only native species. They are also a great source of native grasses. I've had good results with their seed, but results are always better when we get fall rain as we did in 2015.

It sure looks like phlox to me. Probably Fanick's phlox. I don't grow Dame's rocket, but looking at pictures online it seems to have four petals. Phlox has five. Does it have a scent?

Any possibility it's some kind of campanula? They self-sow with abandon in my garden. The rosettes of campanula persicifolia look similar to your pic, though c.p. have pointed rather than rounded leaves.
