Dahlia ‘Collarette Mix’

Product code : VAN-350-113-01

Four multicoloured collarette dahlia tubers produce upright clumps 60 to 80 cm tall and open flowerheads with contrasting inner collars.

The mixture brings several colours and patterns, so every clump provides a surprise. Full sun, fertile compost-enriched soil, and rapid drainage support vigorous stems. Watering at the base when the surface dries prevents prolonged excess moisture. Pinching young shoots encourages branching. Stakes installed early limit breakage.

‘Collarette Mix’ collarette dahlia (Dahlia ‘Collarette Mix’) Collarette Mix dahlia presents a multicoloured collection of four tubers whose open flowerheads combine one row of broad petals, a short contrasting collar, and a visible central disc. This pollinator friendly dahlia produces red, pink, yellow, orange, white, or bicoloured flowers above upright clumps 60 to 80 cm tall. The collarette dahlia mixture creates a spontaneous, airy, changing display while accessible centres welcome visiting insects. Each Van Noort package contains No1 tubers intended to flower from midsummer until frost, providing diversity especially suited to borders and informal summer arrangements. Collarette dahlias develop one outer row of flat florets around a shorter collar framing the central.

Plant all four tubers in spring after the final frost once soil is warm and easy to work. Set them horizontally 10 cm deep with buds facing upward, leaving 40 cm between clumps. Choose full sun in fertile, humus-rich soil that stays moist yet drains freely. Water deeply at the base when the upper layer dries, never allowing water to remain around crowns. Add mature compost before planting, then use fertilizer relatively low in nitrogen and richer in potassium as buds appear. Pinch shoots, install stakes early, and remove fading flowerheads to extend flowering and keep fresh stems developing throughout the season. Collarette dahlias develop.

Use this multicoloured dahlia for borders, cutting gardens, or large free-draining containers. Its visible centres combine well with cosmos, zinnias, salvias, Verbena bonariensis, and airy grasses that also extend resources for pollinating insects. Harvest stems when flowers are nearly fully open and refresh arrangement water often. In Quebec, wait until the first frost blackens foliage, cut stems back, lift tubers carefully, let their surfaces dry, and keep them labelled in a cool, dry, dark, frost-free place. Inspect stored crowns monthly until the next planting season, discarding soft damaged tissue while preserving firm sections that carry healthy viable buds. Collarette dahlias develop one outer row of.
