Heirloom Tomatoes: These are open-pollinated varieties that have been passed down for generations, known for their unique flavors and reliable seed production.
Open-Pollinated Tomatoes: These varieties are pollinated naturally by insects or wind and will produce plants that are true to type.
Hybrid Tomatoes: These are created by cross-pollinating two different varieties and may not produce offspring that are true to type.

Here’s a list of popular heirloom tomato varieties that are excellent for seed saving:

Variety	Characteristics	Flavor Profile
Brandywine	Large, pink fruit, beefsteak type	Rich, sweet, and slightly acidic
Cherokee Purple	Dusky, dark-purple fruit, medium size	Complex, sweet, and earthy
Mortgage Lifter	Large, red fruit, beefsteak type	Mild, sweet, and meaty
Roma	Plum-shaped, red fruit, paste type	Classic tomato taste, slightly tart
Black Krim	Dark, purplish-black fruit, medium size	Smoky, sweet, and slightly salty
San Marzano	Elongated, red fruit, paste type	Rich, intense tomato flavor
Yellow Pear	Small, yellow, pear-shaped fruit, cherry type	Mild, sweet, and slightly tangy
Green Zebra	Green with darker green stripes, medium size	Tangy, zesty, and slightly acidic
Aunt Ruby’s German Green	Large, green fruit, beefsteak type	Sweet, fruity, and slightly spicy
Costoluto Genovese	Heavily ribbed, red fruit, medium size	Intensely flavorful, slightly acidic, and aromatic

Saving seeds from heirloom varieties ensures that you’re preserving unique flavors and characteristics. According to the Seed Savers Exchange, saving seeds from open-pollinated varieties helps maintain genetic diversity and promotes resilient gardening.

3. When is the Best Time to Harvest Tomato Seeds?
