Growing ash gourd (also known as winter melon or white gourd) in Canada, especially in cooler regions, requires starting seeds indoors and using heat-loving techniques. Ash gourd needs a long growing season and thrives in warm, sunny conditions, so starting seeds early and providing a greenhouse or warm environment is crucial for success.
Start indoors 4 weeks before last frost or sow directly outdoors after last frost.
Uses: Great for salads, stuffing, roasting, or on the barbecue
Growing: Sow seeds indoors 6–8 weeks before the last frost, 1/4 inch deep, and keep soil warm. Transplant into 1 inch cells or 2 inch pots at 1–2 leaf stage.
The Principe Borghese tomato is an Italian heirloom famous for sun drying.
They have a thin skin and a thick, very meaty flesh that houses few seeds and little juice, with a rich classic tomato flavor.
Small 1-to 2-oz, grape-shaped fruit is very dry and has few seeds. It has a rich tomato taste that is wonderful for sauces.
An old Italian variety, very suitable for drying and storing over winter. Very productive and healthy plants, that do not need support for growing. Produces intensely red tomatoes that weigh between 30 to 60 g each.
The Tigerella tomato is a popular English heirloom variety prized for its striking appearance and vibrant flavor. Its bright red skin is dramatically streaked with jagged orange to golden-yellow stripes, making it one of the most visually distinctive tomatoes. Tigerella offers a balanced sweet and tangy taste with a lively, zesty kick and a juicy texture. The indeterminate, vining plants are highly productive and begin setting fruit early in the season, producing abundant, round tomatoes about 2 inches (5 cm) in diameter. Well suited to cooler or humid climates and known for good disease resistance, Tigerella tomatoes are excellent for fresh eating, especially in salads, sandwiches, or enjoyed straight off the vine.
