Gladioli ‘Sweet Blue’ produces stunning, large 10–12 cm lavender-purple flowers with a soft, almost velvety texture that adds a touch of elegance to any garden. These graceful blooms sit atop tall, upright stems, making them perfect for creating height and drama in borders or flowerbeds. Plant your Gladioli in a sunny spot—full sun or partial sun works beautifully—ensuring the soil is well-drained for optimal growth. Gladioli look spectacular when planted in clumps, allowing their colour and form to create a bold, eye-catching display. For an even more striking effect, mix them with contrasting colours to make the soft lavender-purple flowers truly pop. Ideal for cutting gardens, borders, or container planting, Gladioli ‘Sweet Blue’ brings a sophisticated splash of colour and texture that lasts through summer.

 

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.

Planting Gladioli in the Garden

• Plant from March to May once the soil has warmed and the risk of hard frost has passed.
• Choose a sunny spot with well-drained soil. Gladioli need plenty of light to flower well.
• Dig a hole 10–15cm (4–6 inches) deep.
• Place the corm with the pointed end facing up.
• Space 10–15cm apart.
• Cover with soil and firm gently.
• Water well after planting.

Planting Gladioli in Pots

• Use a large pot with drainage holes.
• Fill with good quality, free-draining compost.
• Plant corms 10–15cm deep.
• Space a little closer than in the ground (about 8–10cm apart).
• Place in a sunny, sheltered spot.
• Water well after planting and keep compost moist but not waterlogged.

Aftercare / Overwintering

During the growing season:

• Water regularly in dry weather.
• Feed every couple of weeks with a high-potash feed once buds appear.
• Stake taller varieties if needed.

After flowering:

• Allow foliage to die back naturally.
• Once yellow, cut back the leaves.

• Shake off soil and allow to dry.
• Store in a cool, dry, frost-free place over winter.
• Replant the following spring.
