Description

The Dahlia 'Hollyhill Spider Woman' is classified among the cactus-flowered Dahlias, with large-sized heads that have a torn appearance in dark purple and violet colours. You can incorporate a very soft colour mix into your summer flower beds. This category of Dahlia is particularly renowned for its spectacular blooms that allow the creation of magnificent bouquets.

A plant with a thousand faces, the Dahlia, originally from the high plateaus of Mexico, now has around 20,000 varieties resulting from horticultural cross-breeding. This tuberous plant was initially cultivated as a root vegetable for consumption. But its poor taste qualities quickly relegated it to the rank of ornamental plant, much to our delight. Since then, interest in the vitality of this Asteraceae, which is particularly floriferous, has never waned.


The different categories of Dahlias are based on the shape and appearance of the heads. In the group of cactus Dahlias, the heads are fully double, and the ligules are completely tubular and pointed, giving them this unique and characteristic bristly shape. In 'Hollyhill Spider Woman' in particular, the heads measure 15 cm (6in) in diameter and more, and the ligules are so thin and turbinate that they appear as filaments. Some point towards the stem, others towards the centre of the inflorescence, creating the image of a purple and violet spider flower. The bushy clump will reach a height of 100 cm (39in) and a width of 50 cm (20in). The highly branched stems are hollow. The leaves, of medium green colour, are opposite and divided into 3 or 5 denticulate leaflets.

The flowering of Dahlias is exceptionally long, starting in July and ending in November. To encourage repeat flowering, make sure to remove faded flowers. Even better, regularly cut them to create charming, colourful bouquets by combining different varieties.


Easy to grow, Dahlias require some work as they need to be stored over winter. Incorporate them into your perennial flower beds; they will complement summer blooms such as Echinaceas and Cosmos. Also, consider adding grasses to your compositions for delicate mixes with beautiful autumn interest. Traditionally essential in cottage gardens, Dahlias also have their place in the vegetable garden to bring colour to the vegetables.

Planting and care

The 'Hollyhill Spider Woman' Dahlia is easy to grow in all regions. For abundant flowering, following a few simple rules is good: plant the tubers in full sun after the last frost; rich, fresh, and well-drained soils are 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 blood, fish and bone. Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water once abundantly and then renew this watering regularly during the first six weeks to aid in root development. Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost causes the foliage to turn black, 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 10 cm (4in). Spread your bulbs in a crate on newspaper.

Store them in a frost-free, dry, cool, dark place like a garage or attic. In regions in the South, near the coast, where there are only a few days of frost per year, it is possible to leave them in place. In this case, cover the ground with a layer of leaves or straw for protection. This tall Dahlia, with its hollow stems, does not withstand wind or heavy rain well. To overcome this inconvenience, you can stake it, but let's agree, it is not very aesthetic. However, by pinching the stems early or removing the axial flower buds, you will spread out the plant's habit, making it more resistant to bad weather. At the same time, you channel the sap flow to a single flower, which will become larger and more robust.
