Took a bit longer to germinate than I expected, but once they did, the plants were robust. The flavor is fresh and much better than store-bought broccoli. Highly recommend for home gardeners.
First time trying Calabrese broccoli, and I�m thrilled. Seeds sprouted quickly, and the plants matured beautifully. The flavor is superior to supermarket varieties, and my family loved it.
Very impressed with these seeds! Almost every seed germinated, and my garden looks lush. The Calabrese variety produces large heads and tastes great steamed or roasted.
These Calabrese broccoli seeds sprouted beautifully within a week. The plants grew strong and healthy, and the heads were firm and tasty. I love that they�re non-GMO, too. Definitely a repeat purchase for my garden.
These seeds are dependable. I had no trouble with germination, and the plants grew steadily. The broccoli heads were sizable and delicious. Very happy with this purchase.
