Burgundy Velvet Dahlia Bulbs

Darker than most reds and better for it. The petals finish in a matte, light-absorbing surface that looks like velvet rather than lacquer, and the color sits somewhere between oxblood and burgundy. In shade it goes nearly black; the yellow center arrives late and only at full open, which makes the flower look like it’s switching on.

What you get

• Graded tubers with a visible eye, packed in peat.
• Blooms 5–6 in on plants 32–40 in tall.
• Stiff stems — dark dahlias with weak stems are useless in a vase; this one isn’t.

Where it earns its place

Dark red is the cheapest way to give a border depth. Put it behind pale yellows or silver foliage and it works as a shadow; put it next to pink and you’ll see why garden designers avoid the combination.

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.
