Second Early potato producing tubers with yellow skin and pale yellow, firm, dryish textured flesh.
Tender perennial usually treated as an annual crop.

Succeeds in most soils but dislikes very wet or heavy clay soils. Prefers a slightly acid rich soil with plenty of organic matter, the tubers can be subject to scab on limy soils or those deficient in humus. Likes a sunny position.

Plant out tubers in mid April for harvesting in August or September.

The top-growth is not frost hardy, though the tubers will tolerate a few degrees of frost.

From tubers.

Culinary vegetable. Good for boiling, mashing, roasting and frying.
Reliable variety for allotments.

other notes:
Raised in the Netherlands, 1967.

All the green parts of the plant, even green parts of exposed tubers, are poisonous, containing a toxic alkaloid called solanine.
