Iridescent Dawn Dahlia Bulbs

Three colors, one flower. Pink through blue through peach, with a thin gold line along the petal margins that reads as a highlight rather than a stripe. No two blooms come out quite the same — the balance shifts with temperature and with how far the flower has opened.

What you get

• Graded tubers with a visible eye, packed in peat.
• Blooms 4–5 in, fully double, on plants 30–36 in tall.
• Variable coloring — expect the first flowers of the season to be the most saturated.

An honest note

Multicolor dahlias are the category most likely to disappoint, because the marketing shots are taken in the best light of the year. This one genuinely shifts, and in a cool September it can lean almost entirely pink. If you want a fixed color, buy a single-tone variety and leave this one alone.

Planting

• Wait for warm soil. Plant two weeks after your last frost date, once the soil holds 60°F / 15°C at 4 in deep. Cold soil rots tubers before they wake.
• Set them 4–6 in deep, eye facing up, with 2–3 in of soil over the crown. Space 15–18 in apart so air moves between plants.
• Water once at planting, then hold off until shoots break the surface — a soaking wet tuber with no roots has nowhere to put the water.
• Full sun, 6+ hours. Stake at planting if you want straight stems; adding supports later breaks roots.

Season & hardiness

• Blooms 8–10 weeks after planting and keeps going until the first hard frost.
• Hardy in USDA zones 8–11. In zones 3–7 lift the tubers after frost blackens the foliage, or grow as an annual.
• Pinch the center shoot at about 12 in to double the stem count; more stems, smaller blooms.
• Deadhead spent flowers every few days. Left to seed, the plant stops producing new buds.
