I love this little Althea, the color of the blooms are so VIVID and striking. Almost a magenta. If you think all Rose of Sharons are common, you need to see this plant. Blooms are true doubles and last for almost 3 mths here in Indiana. It looks striking with Pink Delight Butterfly Bush, the bloom colors are almost identical and so are the bloom times. I have 2 down by our firepit, planted in rock with zero care and they thrived. Can see blooms from the house and road no problem. I bought mine from a farm store for $5 each. Love a good
