- TrimaineVerified ReviewerRated 5 out of 5 stars11/26/25These seeds are very rewarding
I've successfully grown these in Texas and Oregon, two completely different climates. They have the potential to feed you and your community. I introduced them to my wife and she's had success growing them in both climates as well.

Grows fast. Tastes very mild so far but the plants are still small.
Which best describes you as a gardener? IntermediateBIBotanical Interests11/7/25Hey Susanne,
Thank you so much for the fantastic 5-star review! We're thrilled to hear that you're getting great germination from your Florida Broadleaf Mustard Seeds and that they're growing fast for you!
It's totally normal for the flavor to be mild when the plants are still small. Florida Broadleaf Mustard tends to develop more of its characteristic peppery mustard flavor as the leaves mature and get a bit larger. The younger, smaller leaves are definitely on the milder side, which actually makes them perfect for adding to salad mixes or eating fresh. As they grow bigger, you'll likely notice the flavor becoming more pronounced and developing that nice mustard bite that makes these greens so popular for cooking and seasoning.
They're such reliable performers and can give you multiple harvests if you keep picking the outer leaves and let the center keep producing. You should have plenty of tasty greens coming your way as those plants continue to size up!
Your experience with the germination and early growth will be really helpful for other gardeners who are considering trying these mustard seeds for the first time.
Keep on growing 🌻️
