Stock Incana Early Iron Cherry Blossom

Stock Incana Early Iron Cherry Blossom Seeds

Matthiola incana Early Iron Cherry Blossom is part of the Early Iron series by Sakata Ornamentals. It delivers the delicate, soft cherry blossom pink tone of the Iron Cherry Blossom variety with the added advantage of the Early Iron series breeding, which specifically improves performance during the four shortest-day months of the year when standard Iron varieties experience reduced uniformity and yield.
The soft cherry blossom pink — inspired by the iconic Japanese flowering cherry tree — is one of the most refined and recognizable pink tones in floriculture, carrying a gentle, romantic quality that resonates across cultures and design styles. During the Gulf winter season, Early Iron Cherry Blossom positions itself as the premium soft-pink cut flower option for the November–February production window.

Plant Information

• Height: 60–70 cm
• Spread: 12–15 cm (plant spacing)
• Plant type: Annual
• Flowering: First year
• Sun: Full sun
• Soil: Fertile, well-drained soil, pH 6.0–7.0
• Water: Moderate — reduce gradually as flower buds develop

Growing Tips

• Sow seeds into well-drained germination medium at pH 5.8–6.2 and cover lightly with medium vermiculite.
• Maintain even moisture and a temperature of 18–21°C during the first ten days. After germination is complete, move seedlings to a well-lit area with good ventilation and reduce temperature to 16°C during the day and 10°C at night.
• When seedlings reach two pairs of true leaves, they are ready for transplanting.
• Never delay transplanting as the Early Iron series initiates buds earlier than standard stock varieties and delays will reduce final stem quality.
• Plant 12.5 x 12.5 cm apart in a sunny, well-drained bed at pH 6.0–7.0.
• After transplanting, maintain daytime temperatures below 21°C and nighttime temperatures between 10–15°C. Flower bud initiation requires nighttime temperatures below 15–18°C sustained for 10–21 days.
• Under Gulf winter conditions this requirement is naturally met from October through February, making Early Iron particularly reliable during this window.
• Provide adequate watering until flower buds become visible, then reduce gradually toward harvest.
• Unlike many traditional stock varieties, Early Iron does not require late-season drying conditions to produce tight stems, so maintaining slightly higher moisture levels throughout the crop will support better stem length and quality.
• Use calcium nitrate-based fertilizers and avoid ammonium or urea-based products, as these promote softer growth and thinner stems.
• Provide supporting nets from an early stage and add additional netting as plants grow upward. Spray preventatively for aphids and moths and monitor for Botrytis, Downy Mildew, and Sclerotium throughout the crop cycle.
