It's either a bit late for them or a bit early. Both of those are plants that prefer cool weather and tend to melt away when it is really hot. You might be able to get away with it being in Washington State, where I think your summers are pretty mild. (But I guess that depends on whether you are in coastal Washington or desert Washington). If your area has really hot summers at this point you would be better off to wait a little while and plant the seeds say in August, so by the time the seeds are well sprouted, it will be starting to cool off a bit. With mild winter, your plants might make it all the way through winter and into spring.
