Asperula orientalis

Some germination details:

Although this seed has germinated successfully at 50% within 2 - 6 days when sown around 70*F (*), its germination has also been successful when sown at cold temperatures as in the following:

1) LilyLover's comment above that it self-sows in Utah,
2) Pepsidrinker's success in wintersowing it in zone 5b in March 2007
3) Mr. Deno got better germination (87.5%) sowing at 40*F than at 70*F (50%) in one batch.

Therefore, direct sowing this annual 4 - 6 weeks before last spring frost (like you would poppies), also seems to be a good idea - especially in places with hot summers like ours, where poppies and sweet peas burn up by July.

Blue Woodruff Asperula orientalis is Naturalized in Texas and other States.

This is my favorite self-sowing annual. It's easy to grow from seed, and the lavender blue flowers look nice coming up around larger plants.
