About Dahlia 'Manoa'

Dahlia 'Manoa' produces rounded decorative blooms with layered petals that form a dense, symmetrical flower head.

The deep colour range gives the flowers a velvet-like appearance. In bright light, subtle variations of purple, maroon, and dark crimson become visible.

The flowers continue appearing for many weeks when faded blooms are removed regularly.

This variety works well as a focal plant in borders and is also widely grown for cutting due to its strong stems and long-lasting flowers.
