First seen in the US in 1899, imported from Vilmorin Seeds of France. Also featured in the 1937 McFayden USA Catalogue.
Bicolor, red-and-white globe radish, bright, quick growing and suitable for early and late season sowings. Sparkler is a western-type radish, as opposed to an Asian variety. Also known as White Tip and Sparkler White Tip.
Sow seeds every 2 or 3 weeks for continual harvest. Radishes grow best during the cooler parts of the growing season. Plant in a mostly sunny spot in moderately rich soil kept fairly well watered.
Direct seed once the soil can be worked in early spring. Cover seeds lightly with soil, spacing 1 to 1 1/2 inches apart.
Once established, thin down to 1 1/2 to 2 inches apart. One foot between rows, or plant in beds with equal 2-inch spacing in every direction.
Keep soil moderately moist during the week-long germination period.
Begin harvesting when roots are almost an inch across. Sparkle can mature within 25 days. Once the root becomes visible, they can be pulled.
25 Days average maturity.
