Chris, you are so very welcome!!* Gardening is a hobby for me.* I've been doing it for over 20 years and answering questions on forums for about 6 years now, so I've kinda gotten the research mostly figured out.* My garden is actually very small but it's loaded with plants.*
I hope your knowledge of cancer and chemo is due to your work and not personal experience.*
Btw, I find it very difficult to post on this forum as I use Netscape as my browser and this site isn't all that Netscape friendly.* I see that some of the links I gave you for Penstemon and Salvia either didn't post or were such a mess as to not be any good.* I can't just copy and paste and have to hit 'Control v' to do it.* I'm not kidding when I say 'hit' as that is what I have to do.* I posted and deleted your answer 5 times before I stopped.* I also noticed that the word c0ral for c0ral bells was posted as a bad word.* Go figure!
Remember, just having red in the garden let's the hummers know there is food there.* I once read about a woman who tied red bows on her trees to attract them, and it worked!!* They also like purples and blues.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
