    Grace Seabrook is one of my two favorite rhododendrons. Its blossoms are vivid red; its leaves are dark, dark green. I have a Grace Seabrook plant which is 8 feet tall, (and I am not kidding.) I didn’t grow it so I cannot take credit for the care it must have had to get to that height or the age required. It is pretty sun tolerant in my Bend, OR garden. There are many sunny days during the summer here in the “high desert.” I water it deeply every day and it does very well. It is the first of my rhododendrons to bloom in April. I love it.
