    Customer photo review of Sweet Pea Seeds - Royal Maroon

    These have taken off in the cooler fall weather. They had a rough summer and didnt bloom until the end of August due to our Summer heat in Utah. I love the smell of sweet peas and these smell wonderful......and are by far my favorite color of sweet pea!! I will always plant them in my garden after the great experience growing them this year.
