Gardeners' Notes:

This rhododendron has been described as vigorous and hardy, but I have not had that experience here in Zone 7b. I have had three of them, and all three have not survived a winter, or have barely survived (i.e. two-thirds of plant died). None of them ever put on any real size for me. The blooms are simply beautiful, though, which is why I tried growing it three times. Give it a try, and hopefully you'll have more success than I did. It's so pretty, it's worth it to see if it will grow for you.

I have several azaleas purchased from Lowes. I planted them last year and they were beautiful. Does anyone know what the perfect PH in the soil should be for this plant? Your help is greatly appreciated!

I planted a Percy Wiseman Rhododendron last Spring. It was covered with multi-colored blossoms - pink and yellow and cream. I'm in Zone 5b, but it looks like it has survived its first Winter. I have it in a very sheltered location right next to the house. It has plenty of flower buds - can't wait to see it in bloom again this Spring!

I just planted this as a small I gallon from Lowe's last fall. It has beautiful blooms on it and has become one of my top favorites. So beautiful!
