Chamomile is generally considered a very safe herb, but even 'safe herbs' are not good to take to excess or too frequently without the advice of a medical or herbal professional practioner. They are drugs, you know! And effects may be accumulative. Why not consider sprinkling some lavender oil on your pillow - it will relax and help you sleep and you don't swallow it. Further warnings about chamomile: Sufferers of allergies to daisies, ragweed asters or chrysanthemums should avoid using chamomile. In cases of fragile pregnancy, chamomile should be avoided as it will promote a delayed menses. It may cause stomach upsets in some people.

Different, in my opinion. Arcadia Louisiana Tea's blooms are generally bigger, pinker, more globular, and have more petals and "heft" (they droop more) than those of Rock Hill Peach. In my garden, RHP was a mildew disaster all five years I had it and ACT mildews only slightly, in the worst part of that season.

Do you want these Teas to meet and form a wall? Or do you want spaces between them? Okay, I'll say it outright. "Second Street Tea" has been a complete dud for me, and I bought the #$*!@ thing under two different found rose names. It mildews and gets a leaf spot. Won't grow, either. I can't wait to hack up the second plant for making me look bad. So I doubt it will outgrow the space. :) Le Pactole is a huge thing. It will need every inch of 8 feet. It is trained as a climber over a wide arch in Sacramento. But Sacramento is Zone 9, not 7, so YMMV. Mrs. B. R. Can't may also be bigger than the others (except for Le Pactole). It grew about 8 feet wide within two years in the ground in Zone 9. It won't see another spring here because Mrs. B.R. simply can't open its blooms in my climate, even in this outstandingly dry spring, when there was not one single balled bloom on E. Veyrat Hermanos, the Queen of Balled Blooms. Sawyer Plot Tea/Mme. Lambard/Georgetown Tea will be fine in an 8 foot space. In Zone 9, the largest/widest I've seen was about 10 feet wide, at which time it handled pruning easily. Angel's Camp Tea and Mons. Tillier will also be fine. You'll need to be patient for Mons. T. to fill out because it can have bare knees as a young plant. I can't say where Souvenir d'Un Ami will end up. It isn't breaking any size records right now, although it grew nicely its first season in the ground. I grow Safrano, not Isabella Sprunt. Safrano is not nearly as large as the other Teas in my garden. Even with great age, around here the widest I've seen it was about 6 feet in a very very old plant that was quite vase-like in shape, naked at the base. My plant has foliage right to the ground, but it hasn't made it past 5 feet in....7 years or so. I'm not positive Isabella Sprunt is exactly like Safrano in growth habit. Don't know about the others.

Mangosteen tea is the subject of research here by a couple of universities. They're about to start clinical trials shortly. The focus of their research is schizophrenia. The seeds germinate easily, but they need to be viable, not having been irradiated or chilled. Some fruit have dud seed so it's usually better to get a lot of fruit to increase your chances of success.
