Tall and vigorous even in containers. Strong honey, sweet fragrance. You won’t see many blooms in the picture as they are harvested every day to encourage more.

What a fantastic review! We're absolutely thrilled to hear that your Royal Blend Sweet Pea Seeds are growing so tall and vigorous, even in containers - that really shows how healthy and happy they are in your setup!
Your growing approach sounds absolutely perfect - daily harvesting is such a smart technique and exactly the right way to keep those sweet peas producing abundantly! It's so satisfying when you find that perfect rhythm of cutting blooms regularly because it really does encourage the plants to keep pushing out more and more flowers. Plus, you get to enjoy that incredible honey-sweet fragrance both in the garden and as fresh cut flowers!
We love that you're experiencing that amazing fragrance that Royal Blend Sweet Peas are famous for - there's really nothing quite like that intense, sweet scent that just fills the air around these flowers. And the fact that they're performing so vigorously in containers is such great news for gardeners who might be working with limited space or want the flexibility of container growing.
Your experience with the daily harvest routine will be so helpful for other sweet pea growers! It's such an important tip because many people don't realize how much more productive these plants become when you keep cutting those stems regularly.
Thank you so much for sharing such a wonderful review and for highlighting both the vigorous growth and that incredible fragrance that makes Royal Blend Sweet Peas so special!
Keep on growing 🌻️

Soed the seeds outside 3 weeks ago and the seedlings are now 3" tall. I'm looking forward to watching them grow and enjoying a garden of flowers.

Direct sowed the sweet peas (after soaking the seeds overnight) on 1/20. They germinated 2/1. Thinned them after they had a few true leaves to 6 in. apart. Watered when it's been dry and after hard frosts. They are looking great at 6 inches. It's been very cold at night here so once out zone 8 weather warms up I expect they will really start taking off! Very pleased so far!
