Royal Family Red sweet peas for height
sweet pea seeds in the Royal Family Red type are a classic choice for gardeners who want richly colored, fragrant blooms on a vigorous climbing annual. This variety of Lathyrus odoratus produces red flowers that suit a cottage garden look and bring vertical interest when grown with support. As a trellis climbing flower, it can help add structure to borders, fences, and mixed flower beds while keeping the display light and airy.
Fragrant climbing annual flower with red blooms
These royal family red sweet peas are valued for their strong scent and elegant flower form, making them popular for an ornamental display and for a cut flower garden annual. The plants are known to climb and can reach around 180–200 cm in height under suitable conditions. For best visual impact, place them where the climbing stems can be guided upward and where the red sweet pea flower seeds can develop into a tall, flower-filled screen.
Site preference and garden use notes
This is an annual flower seed for a sunny position outdoors. In the garden, it pairs well with other cottage garden climbing flowers and can be used to soften hard lines around trellises and supports. For indoor arrangements, sweet pea stems are often enjoyed in a vase; keeping vase water low can help reduce stem softening and keep the display looking fresh.
