There's only one 100% reliable method of contraception - and that's abstinence! You have now started a trend. Sex is likely to take place on a regular basis from here on. Both you and your boyfriend need to discuss contraception, together and with someone like a doctor, or a properly qualified herbalist, to find which method of contraception suits you best. Contraception is the responsibility of BOTH partners. Perhaps your partner might consider taking neem. Or perhaps you could each use 'something'. Unless you are prepared to accept a pregnancy and the responsibilities it entails, I think you need to consider something a little more reliable than a herb. Don't rely on herbs. Any herbs. They might, at best, reduce the likelihood of a pregnancy, but not by much. Some of them work by inducing an abortion - and in most cases, that puts both mother and foetus at risk because of the high doses needed for it to be effective. If you want to try the QAL, then you need to take the seeds IMMEDIATELY after coitus. Much like the 'morning after pill'. Which means it's a bit late for you this time!

It depends how strictly native you want to be. I'll plant stuff native to North America, but I find that it's kind of self limiting..stuff that evolved in my region tends to do better. Coreopsis Tinctoria, for instance. I love that plant..it's native to the US, but not my region. I have it, but it doesn't do that well for me. BUT..it's still a native plant. No matter how many years QAL is here, it will never be a native plant.

Queen Anne's lace is quite invasive. I spend a lot of time trying to get rid of it. It will spread everywhere. A nice native host plant for the Black Swallowtail butterfly is the Zizia. There are 3 species native to your area. Common names vary, but most often they are called Alexanders or Zizias. Here is a link that might be useful: Zizia

I've got 3 healthy Rue plants, so don't need to start any, but here's an link on growing Rue from seed. Occasionally I get a volunteer or two. Great plant! Here is a link that might be useful: Growing Rue
