Dahlia Mediterranee

Boasting an exquisitely cool colour palette, Dahlia ‘Mediterranee’ is a true garden showpiece. Its beautifully formed blooms feature soft lavender-flushed petals blending into elegant white, finished with a contrasting deeper violet centre for extra depth and drama. The overall effect is sophisticated and fresh—perfect for lifting borders with cooler tones and creating a calm, stylish planting scheme that still turns heads.

Flowering generously from midsummer right through to the first frosts, ‘Mediterranee’ is also a fantastic choice for cut flowers. The blooms look stunning in arrangements, especially paired with whites, silvers, soft pinks and deep purples. Keep deadheading (or pick regularly) and it will reward you with months of flowers

Planting Instructions

When to Plant:

Plant Dahlia tubers in spring. For the earliest flowers, start tubers in pots indoors from March to April, then plant out once the risk of frost has passed. If planting directly outside, wait until late spring when the soil has warmed.

Where to Plant:
Choose a sunny, sheltered position with fertile, well-drained soil. Dahlias are ideal for mixed borders, cutting gardens and patio containers. They love warmth and perform best in full sun.

How to Plant:

• Depth: Plant tubers about 10–15 cm (4–6 inches) deep, with the old stem (or growing point) facing upwards.
• Spacing: Space plants 45–60 cm (18–24 inches) apart, depending on the final size.
• Soil Prep: Enrich the planting area with well-rotted compost or manure. In heavy soil, improve drainage with grit.

Watering:
Water after planting. Once shoots appear and growth is underway, keep soil evenly moist, especially in dry spells. Avoid waterlogging. Container-grown Dahlias may need watering daily in hot weather.

Aftercare Tips:

• Pinch out the growing tip once plants are around 30 cm tall to encourage bushier growth and more flowers.
• Stake taller stems if needed, especially in exposed borders.
• Deadhead regularly (or cut for the vase) to keep plants flowering until autumn.
• After the first frost blackens the foliage, lift tubers and store dry and frost-free over winter, or protect in the ground with a thick mulch in milder areas.

Top Tip:
To really lean into the “Mediterranean” vibe, plant Dahlia ‘Mediterranee’ with silvery foliage (like lavender or artemisia) and grasses—the warm blooms will glow beautifully against cooler tones.
