Harvesting

The fruit is a berry that is egg-shaped, smooth and has glossy skin. The fruit may measure 4 to 8 inches long. It ranges in color from green to white, to purple-black when immature and when it should be eaten. As the fruit matures it gets stringy and bitter. Fruit contains numerous small, flat, pale yellow to brown seeds.

Color: Vegetable Garden at Paul J Ciener Botanical Garden Vegetable Garden with Pollinator Plants in Mt. Pleasant. Type: Berry. Length: > 3 inches.

Garden value: Edible, Showy

Harvest time: Fall, Summer

Edibility: The immature fruit is edible and best used in food preparation. As the fruit matures, it becomes stringy and bitter. The fruits are usually cooked and served as a vegetable. They may be prepared and eaten by frying, steaming, grilling, roasting, or stewing. They may also be stir-fried, pickled, stuffed, and fried with a light breading.

Storage & Preservation

Fresh Japanese Purple Pickling eggplants store best at room temperature for 2-3 days, maintaining optimal texture for immediate use in stir-fries and tempura. For longer storage, refrigerate unwashed fruits in a perforated plastic bag for up to one week, though the skin may develop brown spots in cold storage.

For preservation, these eggplants excel at traditional Japanese pickling methods β€” slice thinly and salt-cure for quick pickles, or ferment in rice bran for authentic tsukemono. Their tender flesh also freezes well when blanched for 4 minutes and packed in freezer bags, though texture becomes softer upon thawing, making frozen eggplant ideal for cooked dishes rather than fresh preparations.

Dehydrating works exceptionally well due to their low moisture content β€” slice into ΒΌ-inch rounds and dry at 135Β°F for 8-12 hours until leathery. Properly dried slices store for months and rehydrate beautifully in soups and stews.

Frequently Asked Questions

How long does Japanese Purple Pickling eggplant take to grow?β–Ό
Japanese Purple Pickling eggplants take 65-75 days from transplant to harvest, or about 120-130 days from seed sowing indoors. Start seeds 8-10 weeks before your last frost date, then transplant after soil temperatures reach 60Β°F. First fruits typically appear 8-10 weeks after transplanting, with continuous production until frost.
Can you grow Japanese Purple Pickling eggplant in containers?β–Ό
Yes, Japanese Purple Pickling eggplants grow excellently in containers due to their compact size. Use containers at least 5 gallons with drainage holes, and provide sturdy stakes for support. Container plants may need more frequent watering and feeding than garden-grown plants, but often produce earlier due to warmer soil temperatures.
Is Japanese Purple Pickling eggplant good for beginners?β–Ό
Japanese Purple Pickling is considered easy to grow and excellent for beginners. It's more forgiving than large eggplant varieties, produces reliably, and has good disease resistance. The main challenge is providing consistent warmth, but in zones 5-10, most gardeners find it straightforward with proper timing and soil preparation.
What does Japanese Purple Pickling eggplant taste like?β–Ό
Japanese Purple Pickling eggplant has a mild, sweet flavor with tender, creamy flesh and absolutely no bitterness. The texture is silky and cooks quickly without becoming mushy. It absorbs flavors well while maintaining its shape, making it ideal for stir-fries, tempura, and traditional Japanese preparations where delicate texture is prized.
When should I plant Japanese Purple Pickling eggplant?β–Ό
Start seeds indoors 8-10 weeks before your last spring frost date, typically in February or March for most regions. Transplant outdoors 2-3 weeks after your last frost when soil temperatures consistently reach 60Β°F and nighttime temperatures stay above 50Β°F. Rushing transplanting into cool soil significantly reduces plant vigor and yield.
How do you pickle Japanese Purple Pickling eggplant?β–Ό
Slice eggplants thinly, salt lightly, and press for 30 minutes to remove excess moisture. For quick pickles, combine with rice vinegar, sugar, and salt. For traditional tsukemono, layer with rice bran and salt, then ferment for several days. The tender skin and mild flesh make these eggplants perfect for both quick and fermented pickle preparations.
