Growing Info
Harvesting: Snap beans are ready to pick when the pod "snaps" or breaks in half cleanly. This is when seeds have just begun to form and the pods are several inches long (depending on the variety). Hold stem with one hand and the pod with the other hand to avoid pulling off branches, which will continue to produce. Harvesting early and often will stimulate flower production for more beans. At season's end, plants are great compost material if they are disease-free.

These bean vines grew quickly & voraciously such that I had to trim them. The vines themselves are decorative. The beans were plentiful, 5-7 inches long, and very flavorful. Almost sweet. (Just don't wait until they are too large, as they get tough.) I will be planting these every year!

What a fantastic review! We're absolutely thrilled to hear that your Trionfo Violetto Pole Beans have earned the title of "best beans ever" - that's such high praise and we couldn't be more excited!
Your growing experience sounds like it went amazingly well - those vigorous, fast-growing vines that needed trimming really show how happy these beans were in your garden! It's so wonderful when a variety exceeds expectations with that kind of enthusiastic growth. And you're absolutely right about the decorative value - Trionfo Violetto beans are such beautiful climbers with those gorgeous purple pods that really make a stunning visual impact in the garden.
We love that you discovered that perfect sweet spot for harvesting at 5-7 inches! Your tip about not waiting too long before they get tough is such valuable advice for other gardeners. There's definitely that sweet window where these beans are at their absolute peak - tender, flavorful, and with that almost sweet taste you mentioned. It's clear you really dialed in the perfect timing to get the best eating experience.
The fact that these beans were so prolific and delivered on both the visual appeal and incredible flavor really highlights why Trionfo Violetto is such a special variety. When you find a bean that grows beautifully, produces abundantly, and tastes amazing, it's definitely worth making it an annual tradition!
Your enthusiasm about planting them every year is the best endorsement we could ask for!
