Best Zucchini Varieties for Open Ground
Most zucchini grown in open fields are low-maintenance and don’t require special skills. They can be planted either as seedlings or directly sown. Zucchini easily tolerate frost, rain, and windy conditions.
Gold Rush
A type of courgette, this variety produces elongated, bright yellow fruits. The average weight is around 0.7 kg, with a length of up to 15 cm. The flesh is golden-yellow, sweet, and crisp. It retains its flavor after cooking, making Gold Rush ideal for canning and pickling. The high sugar content gives dishes a rich sweet-and-sour taste.
Gold Rush is an early-maturing variety, ready for harvest 45–50 days after planting. The bushes are compact, reaching no more than 0.5 m in height. While low-maintenance, they require regular watering and feeding. Water every 5 days, or every 3–4 days during hot, dry summers. Morning or evening watering is best to avoid sunburn.
Starling
Another courgette variety, Starling, is grown across Europe. It offers consistently high yields and strong disease resistance. The fruits are long, about 25–30 cm, weighing between 0.5 and 1.2 kg. The skin is thick, with a dark green color and white streaks.
Starling is an early-maturing variety with excellent shelf life. To maximize storage, wipe the zucchini dry and keep them in a cool, dark place like a cellar.
Did you know? The word "courgette" comes from French, while "zucchini" originates from Italian, meaning "little pumpkin."
Zucchini Tree F1
A hybrid combining easy care with high resistance to adverse conditions. The name comes from the plant’s growth habit—its vigorous vines reach 4–5 m, often climbing nearby trees for support, creating the illusion of growing on a tree.
Zucchini Tree is a mid-season variety, maturing in 70 days. The fruits are elongated, slightly oval, and up to 15 cm long. They have a pale green hue and excellent flavor. The skin is soft and smooth but hardens as it matures.
With a neutral taste and aroma, this zucchini pairs well with various dishes. It’s perfect for soups, side dishes, salads, and healthy diets, being rich in vitamins and minerals.
Black Beauty
A high-yielding, early-maturing variety named for its dark green skin. It matures in 40 days, yielding about 3 kg per plant. It’s best grown from seedlings, prepared 30–40 days before transplanting. Seeds should be disinfected with potassium permanganate or hydrogen peroxide and pre-sprouted in a damp cloth.
Plant in May after the last frost. Ideal predecessors are legumes or onions. Black Beauty thrives in loamy-sandy soil. The fruits are small, weighing 0.8–1 kg, and store well without losing quality.
Cavili
A hybrid variety ready in 50–60 days. Cavili produces fruit for about two months, yielding up to 10 kg per sq.m. The cylindrical, light-green fruits have juicy, pale-green flesh, perfect for ratatouille. The thin skin means they should be used quickly.
Plant after potatoes or onions—never after cucumbers or pumpkins. Water when the soil dries, preferably with rainwater. Though disease-resistant, preventive measures like soap or ash sprays are recommended.
Buccaneer
A hybrid for lovers of large, heavy fruits. Round zucchini weigh 3–4 kg, yet the bushes remain compact. Buccaneer matures in 40–44 days and yields abundantly. The flesh is light green, the skin dark.
For higher yields, fertilize every two weeks with organic or mineral supplements like urea, ammonium nitrate, liquid manure, or ash. Apply before watering for best results.
Charisma
A hybrid variety maturing in 40–45 days, with high yields per plant. The compact fruits weigh up to 0.7 kg, with a pale-green color and slightly sweet flesh. The soft skin makes them easy to peel and process. Fruiting is prolonged, typical of hybrids.
Charisma resists common fungal and viral diseases. Preventive treatments include Bordeaux mixture or copper sulfate sprays. Adding ash or lime before planting improves soil fertility and reduces acidity.
Aral
Medium-sized bushes with vibrant green leaves. Low-maintenance, Aral yields up to 10 kg per sq.m. The light-green fruits have smooth, thin skin, measuring 15–20 cm and weighing around 500 g. The dense, flavorful flesh has few seeds, making it great for preserves and side dishes.
Did you know? 100 g of zucchini contains only 24 kcal. Rich in vitamins B1, B2, A, C, and PP, it also provides magnesium, calcium, potassium, and iron. Dietary fiber aids digestion and lowers cholesterol.
White Swan
An early-maturing variety with smooth, cylindrical white fruits. White Swan thrives even in cooler climates like Scandinavia. It prefers organic fertilizers like poultry manure, peat, or compost. Adding river sand improves soil texture.
This zucchini is a culinary favorite—ideal for pancakes, salads, pickles, stews, and casseroles. It retains nutrients whether baked, boiled, or fried.
Iskander
A hybrid popular across Europe. Pale-green with white streaks, the fruits weigh about 500 g and measure 18–25 cm. Iskander yields up to 17 kg per plant, making it great for home use and sale.
Plant in late March for harvest by May–June. Ripe fruits sound hollow when tapped, and the skin hardens. Store for no more than 5 months to preserve quality.
Medusa
An ultra-early hybrid maturing in just 35 days. The green fruits are small, with few seeds and juicy flesh. They grow up to 25 cm long and weigh about 800 g. Heat-treat seeds at 40°C for 5 hours before planting to reduce disease risk.
Black Beauty
A bush variety fruiting in 45 days. The glossy, dark-green fruits weigh 1–1.5 kg. The white flesh is tender and flavorful. It grows well in cool, rainy conditions. Store in a cellar or fridge.
How to Choose the Right Variety
Your choice depends on your goals. For fresh eating or pickling, opt for Medusa, Iskander, or Black Beauty. For long storage, choose Cavili, White Swan, or Gold Rush, thanks to their thick skins.
Low-maintenance options like Iskander, Charisma, and Aral suit busy gardeners. Climate matters too. Aral and Black Beauty excel in warmer regions, while hybrids like Iskander and Buccaneer tolerate cooler areas.
