This is Dahlia ‘Gallery Art Nouveau’, a medium sized Dahlia cultivar, that produces these handsome, vibrant pink coloured flowers. I’d say that Dahlia ‘Gallery Art Nouveau’ produces medium sized blooms. One thing that I want to highlight right away, is that Dahlia ‘Gallery Art Nouveau’ flowers are not accessible to bees, butterflies, and other pollinating insects. So if you’re looking for bee friendly plants for your garden, this is not one to add to your list! Here’s a link to my Dahlia plant pages, where you’ll find some super plants for bees, hoverflies, and butterflies.
Dahlia ‘Gallery Art Nouveau’ is a slightly tender plant. Many plants survive the winter, but not all do – so you cannot bank absolutely on your plant being a survivor. Dahlias that have the best chance of survival and grow on to flower another year, tend to have been grown in free draining soil that isn’t waterlogged in inclement weather.
If you live in a colder or wetter area of the country, you might wish to lift your Dahlia tubers in the autumn, and store the tubers overwinter. If you plan to lift your Dahlias, wait until your Dahlia’s leaves have blackened in the cold. Lift your plants on a dry, sunny day, and then move your plants somewhere dry and frost free with good air circulation, where they can dry out. I haven’t lifted all of my Dahlias for some years now, simply because my Dahlias are all grown in free draining sandy soil, so the plants have a much better survival rate! I used to place my Dahlias on a tray of dry compost and they spent winter there in a cold, but frost free place with good air circulation – a garage is ideal.
Plant Dahlia ‘Gallery Art Nouveau’ in mid to late spring a warm, sunny spot, where this tuberous perennial will enjoy the sunshine. Plants can be started off inside a cold glasshouse. Like all Dahlias, Dahlia ‘Gallery Art Nouveau’ grows best in moist, but well-drained soils. Your plant might need staking. Alternatively, you could use a woven structure, to support your plants.
Dahlia ‘Gallery Art Nouveau’ plants will grow to around 60cm (2ft) tall – although the overall height and appearance of the plant will be reflected in the particular plant’s growing conditions.
