Lake Valley Seed Sweet Pea Royal Family

Yes, sweet pea seeds have a hard outer coat that benefits from preparation. For better germination rates, nick the seed coat slightly with a file or knife and soak the seeds in water for a few hours before planting.

These are vigorous climbers that reach a mature height of approximately 72 inches. Because of this height, they require a sturdy support structure like a fence, trellis, or netting to grow properly.

While they are excellent for fences and trellises, you can grow them in containers if the pot is large enough to support their 6-foot height and deep root system. Ensure the container has excellent drainage and a tall, stable trellis for the vines to climb.

The secret is consistent deadheading. Regularly snip off faded blooms and remove any developing seed pods to prevent the plant from putting energy into seed production, which encourages it to keep flowering.

Sweet peas are cool-season annuals that bloom in early spring. As temperatures rise significantly, they will naturally decline, so they are best suited for gardens where spring weather remains mild.

They thrive in full sun, which helps produce the most blooms. However, if you live in a warmer climate, they will appreciate some protection from the intense afternoon sun to keep the plants from wilting.
