Purple & Green Tomatillo Seeds – 2 Unique Varieties

Purple & Green Tomatillo Seeds for Planting – 2 Unique Varieties – Purple Tomatillo & Rio Grande Verde Tomatillo (Physalis philadelphica) include two distinctive tomatillo varieties with different fruit colors and flavor profiles. Purple Tomatillo produces round fruits that mature from green to deep purple, with a slightly sweeter, fruitier flavor and a colorful appearance that makes them ideal for fresh salsa, roasting, and garnishes. Rio Grande Verde Tomatillo produces larger, bright green fruits with a classic tangy, citrus-like flavor commonly used for salsa verde, sauces, soups, and traditional Mexican dishes.

The main difference between these two varieties is color, flavor, and fruit size. Purple Tomatillo is known for its striking purple color and slightly sweeter taste, while Rio Grande Verde produces larger green fruits with the familiar tart, savory flavor associated with traditional tomatillos. Both develop inside papery husks and are productive warm-season plants that benefit from growing more than one plant for better pollination and fruit set.

Planting Season

Best planted in: Spring & Early Summer (Warm-Season Crop)

Start seeds indoors approximately 6–8 weeks before the last expected frost. Transplant outdoors after all danger of frost has passed and nighttime temperatures consistently remain above approximately 50–55°F (10–13°C).

Tomatillos grow best in warm conditions between approximately 65–85°F (18–29°C) with full sun.

How to Grow Purple & Green Tomatillo Seeds

Start seeds indoors in trays or small pots filled with moist seed-starting mix.

Sow seeds approximately ¼ inch deep.

Maintain soil temperatures between 70–85°F (21–29°C) for reliable germination.

Keep the soil evenly moist but not waterlogged.

Seeds typically germinate within approximately 7–14 days.

Provide strong light after germination and harden seedlings outdoors for approximately 7–10 days before transplanting.

Choose a location receiving at least 6–8 hours of direct sunlight daily and provide fertile, well-drained soil enriched with compost.

Space plants approximately 24–36 inches apart. For good fruit production, grow at least two tomatillo plants near each other to improve pollination.

Plants develop broad, branching growth and may benefit from cages or stakes, especially when heavily loaded with fruit.

Container growing is possible in large pots with excellent drainage.

How to Care for Purple & Green Tomatillo Plants

Water deeply and consistently, allowing the upper soil surface to dry slightly between waterings.

Apply mulch around established plants to conserve moisture, suppress weeds, and maintain even soil conditions.

Feed with a balanced vegetable fertilizer during active growth, but avoid excessive nitrogen once flowering begins.

Provide cages or stakes if branches begin to spread or bend under the weight of developing fruits.

Monitor for common pests such as aphids, flea beetles, hornworms, and whiteflies. Good spacing and airflow help reduce disease problems.

Purple Tomatillos generally mature in approximately 70–90 days. Harvest when the husk becomes full and begins to split, and the fruit inside develops a rich purple color.

Rio Grande Verde Tomatillos generally mature in approximately 75–85 days. Harvest when the fruits completely fill their husks and the papery covering begins to dry or split.

Remove the husks before use and rinse away the naturally sticky coating from the fruit. Fresh tomatillos can be refrigerated for short-term storage or roasted, frozen, or made into salsa and sauces for longer preservation.
