I learned some things too! Like that I need one. Or two. ;-) Thank you for a great article, darius. Have you seen red-twigged and yellow-twigged varieties growing together? Wondering how it would look.
I remember, during those years when I was the single mother of two small girls, very solemnly planting a dead dried up stick of a "red twig dogwood" from one of those companies that gets a very bad rating in the Garden Watchdog. Of course, it stayed dead.
Now, I see again that I really do need one! So, I thank you for the information and the inspiration!
I've had success with rooting the RTD. I take cuttings about 8 inches long from fresh growth, dip in rooting hormone and poke into damp sand. Keep them in bright light, but not full sun. They rooted quickly.
