Description
Dahlia Mondriaan is a decorative dahlia with small, semi-double flowers that evoke water lilies in soft shades of yellow and pink. The flowers are carried well above the foliage on sturdy, not very tall stems. This beautiful flowering can be enjoyed from July until the first frost, both in borders and in bouquets.
Dahlias are tuberous plants belonging to the large family of asters, originally from the high plateaus of Mexico. Nowadays, the thousands of horticultural varieties created by humans have invaded gardens all over the world, much to our delight. These tuberous plants are not very hardy. Dahlias are classified according to the shape of their flowers. 'Mondriaan' is classified in the category of decorative dahlias. In this group, the colourful ligules of the head are arranged regularly in a spiral, they can be curved towards the stem or curled, for example. In this variety, the heads measure about 12cm (5in) in diameter and their ligules are widely oval, slightly pleated, almost flat. The flowering takes place from July to October-November. Depending on the ripeness of the flower, the light yellow colour of this variety becomes tinged with pink on the periphery. The plant will reach a height of between 85 and 90cm (34 and 35in) and a width of 50 to 60cm (20 to 24in), with a bushy and erect habit. The very branched stems are hollow and the leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 leaflets, which have very toothed lobes. The leaves are quite dark green and the stems, which are sturdy, are more or less tinged with purple.
To encourage repeat flowering and extend the flowering period, be sure to remove faded flowers. Even better, regularly create attractive colourful bouquets by combining different varieties. Decorative dahlias go well with Gauras, Cleomes and Statices, which will lighten their generous silhouette. 'Mondriaan' flowers also allow for beautiful combinations in floral compositions, with yellow, orange and white varieties. The modest size of this variety makes it suitable for the centre of mixed borders, to structure a composition made up of bushes with colourful foliage (Physocarpus, Compact Winged Spindle, Loropetalum...) and shorter plants. Also consider ornamental grasses (Briza, small Miscanthus, Stipa, Eragrostis) which take on beautiful colours in autumn.
As the star of cottage gardens, Dahlias are undoubtedly beautiful flowers. They are perfect in a flower bed, but can also enhance a vegetable garden. In Mexico, this tuber was initially grown as a root vegetable for consumption. Its poor taste quickly relegated it to the status of an ornamental plant.

Planting and care
The decorative Dahlia 'Mondriaan' is easy to grow in all regions. For abundant flowering, it is good to follow a few simple rules. Plant the tubers in a sunny location as soon as the last frost has passed. Rich, fresh, and well-drained soil is perfect. However, stagnant moisture would promote tuber rot. Feel free to amend the soil with compost and sand if necessary. Work the soil deeply and enrich it, for example, with crushed horn or dehydrated blood. Place your tuber and crumble the soil well to refill without air pockets. Your dahlia should be covered with about 6cm (2in) of soil. At the end of planting, water once abundantly and then regularly renew this watering for the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frosts cause the foliage to blacken, which is the time to dig them up. Carefully remove the tubers from the ground, removing as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10cm (4in). Spread your bulbs in a crate on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or an attic. In southern regions near the coast, where there are few frosty days per year, it is possible to leave them in place. In this case, simply cover the ground with a layer of leaves or straw for protection.
Despite its hollow stems, this Dahlia is still sensitive to strong wind or heavy rain. To mitigate this inconvenience, you can stake it, but let's agree, it's not very aesthetic. However, by pinching the stems early or removing the axial flower buds, you can spread out the habit of the plant, which will offer more resistance to bad weather. At the same time, you channel the sap flow to a single flower, which will become larger and stronger.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
