Gladioli Blue Isle will produce large 10-12cm, vibrant violet-purple flowers that appear almost velvety. We recommend planting your Gladioli in a sunny position (full sun or partial sun is fine) with well-drained soil. Gladioli look fantastic planted in clumps. Choose contrasting colours for your groupings to really show them off. 

 

Harts' Hint
Gladiolus can be planted about 2 weeks before the last expected spring frost. Gladiolus will take 70-90days to flower. For a continual display of flowers, plant a few corms every 2 weeks until early summer.

• Position your corms in Full Sun to partial shade in well-drained, moist soil.
• Plant your corms 10-16cm (4-6") deep and 10cm (4") apart. 
• Plant in pots or directly in the garden. 
• See 'Care Instructions' for protecting over the winter months.

• If in pots, stop watering at the end of summer and bring them indoors for winter to protect against frost.
• Place back outside once the danger of winter frosts has passed. 
• If planted in the garden, we advise to lift and store your Gladioli corms for winter, store them in a breathable bag (like a paper bag) and ensure the air is able to circulate around the corms. Keep the corms in a cool, dry spot like a garage or shed. 
• In mild parts of the country, you can keep your corms planted in the ground over winter but it is a risk, just mulch them over deeply with 6-7cm (2.5").
