Growing Instructions from Seeds

• Method: Sow individually in deep nursery pots

• Sowing Depth: Approximately 0.5–1 cm

• Seed Position: Place seeds on their edge

• Germination: Approximately 10–30 days

• Ideal Germination Temperature: 18–24°C

• Transplanting: After seedlings establish healthy roots and several true leaves

• Spacing: Approximately 60–90 cm for garden planting

• Support: Strong trellis, pergola or climbing frame required

Avoid damaging roots during transplanting. Germination may be slow or uneven, so maintain warmth and gentle moisture without saturating the medium.

Sunlight & Watering

Sunlight: Full sun to light partial shade. Provide afternoon protection during extreme summer heat.

Watering: Maintain consistent moisture during active growth, allowing excess water to drain freely.

Growth & Flowering

• Growth Habit: Vigorous, tendril-climbing vine

• Flower Colour: Creamy white

• Flower Shape: Bell-shaped with prominent green calyces

• Flowering: After the plant establishes sufficient growth, depending on temperature and sowing time

• Life Cycle: Tender perennial in frost-free conditions

Provide a strong climbing structure and guide young shoots onto the support.

Feeding

Apply GREEN GARDENS Vermicompost at planting and during active growth as needed.

Avoid excessive nitrogen feeding, which can encourage vigorous leaves and stems at the expense of flowering.

Perennial Care

White Alba is botanically a perennial but is not frost-hardy.

In frost-free, sheltered locations, established plants may continue growing for multiple seasons. In colder areas, protect plants during winter or maintain them under cover.

Trim excessive growth when necessary and maintain strong structural support.
