Description

The ultra-cheerful semi-cactus Dahlia 'Yellow Happiness' is not quite as spiky as some of her kinsfolk in the dahlia family. Her long petals do not turn back on themselves as tightly, making less tubular spikes than those of cactus dahlias. Perhaps that’s what makes her as cheerful as she appears. Add to that the bright sunshine yellow she displays in multiple flower bursts on her compact bushy plant, and there’s a lot of cheer going on.

Dahlia 'Yellow Happiness' is shade tolerant but likes full sun, so it’s best where possible to let her try and outshine the late summer sun where possible. She’ll surely outshine autumn’s less bright sunlight.

Useful information

    • Dahlia 'Yellow Happiness' 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 'Yellow Happiness' 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.

Dahlias in 60 seconds

Dahlias like full sun and a free-draining soil, and should be lifted and stored in winter, or at least protected with peat or straw. Dahlia flowers can range from 5 to 25cm in diameter and those magnificent larger-flowering dahlias might appreciate a little extra support with canes!
