Frequently Asked Questions

Sweet Pea

We offer consumer-friendly sweet pea flower seeds that are easy to grow and suitable for gardeners of all levels, from beginners to experts.

What is the difference between climbing and dwarf sweet pea varieties?

Climbing sweet peas, such as Ferry-Morse Early Gigantea and Early Flowering Mixed Colors, produce long vines suitable for trellises, fences, and cut-flower gardens. Jet Set Mixed Colors (Knee-Hi) is a shorter, semi-dwarf variety suitable for borders and containers.

Are sweet pea flowers and seeds edible?

No. Ornamental sweet peas (Lathyrus odoratus) are not edible. Their seeds and other plant parts can be toxic if consumed. Do not confuse ornamental sweet peas with edible garden peas (Pisum sativum). Keep sweet pea seeds and plants away from children and pets who may ingest them.

How can I encourage sweet peas to produce more flowers?

Cut sweet pea flowers regularly or remove faded blooms before seedpods develop. This helps encourage continued flowering rather than seed production.

Can sweet peas grow in containers?

Yes. Sweet peas can be grown in containers with adequate drainage and sufficient depth for root development. Choose a container appropriate for the variety's mature size, and provide support for climbing varieties.

Do sweet pea plants need a trellis?

Climbing sweet pea varieties benefit from a trellis, fence, or other support. Compact varieties, such as Ferry-Morse Jet Set Mixed Colors (Knee-Hi), generally do not require staking.

Do sweet peas need full sun?

Sweet peas grow best in full sun. In regions with hot summers, a location with morning sun and some afternoon shade may help protect plants from excessive heat.

What temperature is best for germinating sweet pea seeds?

Sweet pea seeds germinate well in cool conditions. An optimum germination temperature of approximately 55°F (13°C) is recommended.

Should I start sweet pea seeds indoors or sow them directly outdoors?

Sweet pea seeds can be sown directly outdoors or started indoors for an earlier start. If starting seeds indoors, use deep individual pots or biodegradable containers to accommodate their developing roots and minimize root disturbance when transplanting.

When should I plant sweet pea seeds?

Sweet peas (Lathyrus odoratus) grow best in cool weather. In regions with cold winters, sow seeds in early spring as soon as the soil can be worked. In mild-winter climates, sweet pea seeds can also be sown in fall for flowers the following spring.
