Dahlia Mom's Special

Dahlia ‘Mom’s Special’ is a wonderfully cheerful variety with blooms that feel instantly celebratory—like a bouquet already arranged on the plant. The flowers are beautifully bi-coloured, typically blending soft creamy tones with brighter pink or rosy markings, giving each bloom a lively, slightly different look. It’s a perfect choice for adding charm to sunny borders and patio pots, and it’s especially lovely in a cutting garden where you can enjoy those pretty, mixed colours indoors too.

Flowering from midsummer right through to the first frosts, ‘Mom’s Special’ is a generous bloomer. Keep deadheading (or pick for the vase) and it will keep sending up fresh flowers for months

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:
Because the blooms are naturally varied and bi-coloured, Dahlia ‘Mom’s Special’ looks brilliant mixed with simpler single-colour flowers—it lets those pretty markings really stand out.
