White Aster: Pom Pom Dahlia Tubers

After 120 odd years, White Asters are one of the best white pompom dahlias you can grow for your garden. The profuse, tightly packed pompoms are 5-6 cm across and mostly soft white, with a slightly creamier, faintly yellow centre. It is a superb pot plant and has a great vase life.

Growing White Aster Dahlias

All dahlias do best in deep rich soil with good drainage in a sunny spot. If it is windy they will need staking. They are greedy, thirsty plants so will need watering in dry spells, and they will always flower that little bit better if there is a bit of soluble food in the watering can once every couple of weeks.

White Aster generally does not grow to more than 75 cm and if you pinch it out at about 30-40cm, you will get more flowers on a lower plant, which won't need staking in a sheltered location. Even so, a few canes and some string will protect it if you get a gale.

It is generally more convenient to put support stakes in at planting time, rather than leaving it until there is foliage in the way.

Did You Know?

There is another dahlia of the same name, a decorative variety introduced in 1879, that is widely thought to be the oldest surviving garden dahlia in commercial cultivation. This one is almost as venerable, bred around 1901, and listed in old books as Guiding Star.
