These seeds sprouted quickly, and the plants are thriving. The tomatoes are full of flavor, just like the classic San Marzano I remembered from Italy. Definitely a must-grow for any tomato lover.
I wasn�t sure how these would do in my small backyard, but they grew beautifully. The fruit is meaty and perfect for sauces. I�m thrilled with the results.
I�ve tried many tomato seeds, but these really capture that classic San Marzano taste. They are slightly sweet with rich acidity�ideal for pasta sauce.
Planted these a few months ago, and the yield is impressive. The tomatoes have thick skins and hold up beautifully when cooked.
The seeds took a little longer than expected to germinate, but once they did, the plants grew strong and healthy. The tomatoes taste fantastic and are worth the wait.
