This scarlet beauty, Royal Sweet Pea Scarlet or Lathyrus Odoratus, is a profuse bloomer. What a show for the garden! This annual climber is easily grown from Sweet Pea flower seeds, and it is suited for container gardening, hanging baskets, or as a climbing vine on a trellis or arbor.
Royal Sweet peas grow as a 72 - 84 inch annual across the country in USDA zones 3 - 9.
Sweet Pea flower seed can be directly sown outdoors in a sunny location. Place Sweet Pea in a sunny location but also where it can be cool in the heat of the day if at all possible.
They actually bloom better when the temperatures are cooler. Position Sweet Pea away from winds and change locations each year to prevent Sweet Pea pests.
