Sierra Blanca F1 Onion (Super Star)
Allium cepa
Price: $3.95
SKU: 32800621110 days to maturity. Sierra Blanca is a hybrid white onion, formerly sold as Super Star. It is intermediate-day, meaning it does not need long days or short days to form a bulb the way most onions do. It grows well across almost all of North America. The bulbs are globe shaped with snowy white skin and matching white flesh inside. Most are 3 to 4 inches across, and with an early start they often reach the jumbo to colossal range, with some bulbs growing up to a pound or more. The rings are thick, crisp, and sweet, with a mild to moderate flavor. Compared to White Sweet Spanish, its closest match, Sierra Blanca is sweeter, milder, and larger.
The plants carry strong, tall, dark green foliage that shades the bulbs and helps prevent sunburn. That same foliage makes the onions attractive to sell in bunches with the tops still attached. The variety is bolt tolerant and resistant to pink root. Storage potential is about two months, so plan to use or sell the crop rather than hold it through winter. Sierra Blanca won an All-America Selections award in 2001.

Planting Instructions:
Onions have a shallow root system and are adapted for well drained, rich, loam-type soil. Either start seeds indoors, or directly into the garden, in a sunny location, from April to mid-July.
Plant onion seeds ½ inch deep, two to four seeds per inch in rows spaced twelve to sixteen inches apart. Thin the plants to four inches apart to allow the bulbs room to develop. Use thinnings as green onions.
