Description
Embrace the pastels or use Dahlia 'Mondriaan' to add a contrasting highlight among darker tones. This dahlia not only brings subtle, soft colour to the garden, but a touch of understated elegance to bouquets too. This classy decorative dahlia features semi-double blooms in a soft shade of lemon cream washed with pink on its outer petals. Its beautifully-formed flowers are long-lasting and perfectly sized for flower arranging. The soft pastel tones of Dahlia 'Mondriaan' are easy to match with other gentle colours, and create a calming and peaceful mood in the garden.
Dahlia 'Mondriaan' forms a bushy plant and produces flowers on long, strong stems. The size of the flowers is around 12cm, making this an ideal choice for a cut flower: not too small to be un-noticed, but not too big to dominate. It will produce blooms over a long season in summer and autumn if regularly cut or deadheaded, and if the tubers are protected overwinter, can become a regular annual feature in either containers or borders. In warmer climates, a thick mulch over the Dahlia 'Mondriaan' tubers will often suffice, while in colder areas lifting the tubers and storing them in a cool, frost-free place over winter will help to ensure that these beautiful blooms will grace your garden for years to come.

Useful information
-
Dahlia 'Mondriaan' is half hardy, which means that it should be kept frost free over winter and during spring.
For best results, start your dahlia tubers in temporary pots in a
greenhouse in March or April to grow on to transplant outside later in the season—this will give them a head start.Alternatively, you can plant the Dahlia 'Mondriaan' tubers directly outside in May.
Plant with the stump of last year's stem facing upwards. The tuber should be fully submerged but with the stump just below the soil surface.
Plant one tuber per 8-10" pot if growing on during spring. When
planting outside, space the tubers around 30-50cm apart from each other. Compact varieties don’t need so much space.Water-in thoroughly after planting and continue to water regularly once in full growth, but only when the soil appears to be nearly dry.
