Similar in some ways to the Anemone-Flowering Dahlias, the Collarette Dahlias seem to be serving a central flower on a flat platter of large, slightly involute petals. The “inner” flower is made up of a collar of short petals that curl upwards to form a ruff around the bloom’s centre. These are spectacular blooms with the colour contrast between the ruff and base petals resulting in a particularly dramatic flower. Collarette Dahlias fall into the small to medium size range, which means their flowers are unlikely to top a diameter of 15 cm (6 inch), but could be as small as 10 cm or 4 inch. Their compact plants are usually no taller than 60 cm (2 feet) but some do grow to 90 cm (3 feet).
