Dahlia Decorative ‘Sam Hopkins’ is a dramatic decorative dahlia prized for its rich, velvety coloration and bold garden presence. The large, fully double blooms are composed of broad, gently pointed petals that overlap in lush layers, forming flowers with impressive depth and substance. The color is a deep, luxurious wine-red to burgundy, often appearing almost black in low light, with a subtle sheen that catches the sun and enhances its intensity. This saturated hue makes ‘Sam Hopkins’ one of the most striking dark dahlias available, providing powerful contrast among lighter flowers and foliage.

Blooms typically measure 5–7 inches across and are held on sturdy, upright stems above dense, dark green foliage. The plants are vigorous and productive, delivering a steady supply of flowers from midsummer until frost. In the garden, ‘Sam Hopkins’ adds drama and sophistication, while in floral arrangements it brings richness, depth, and a sense of luxury. Its long stems and strong petals make it an excellent cut flower, ideal for both bold modern designs and classic, elegant bouquets.

Planting Directions

• When to Plant: Plant tubers in spring after all danger of frost has passed and the soil has warmed.

• Sun Exposure: Choose a location with full sun, providing at least 6–8 hours of direct sunlight each day.

• Soil: Plant in fertile, well-drained soil. Improve heavy or compacted soils by incorporating compost or well-rotted organic matter.

• Planting Depth: Dig a hole 4–6 inches deep. Place the tuber horizontally with the eye or growing point facing upward.

• Spacing: Space plants 18–24 inches apart to allow for mature growth and good air circulation.

• Watering: Water lightly after planting, then wait until shoots emerge before watering regularly. Once established, water deeply and consistently, allowing the soil surface to dry slightly between waterings.

• Staking: Install stakes or support at planting time to prevent wind damage and to support large, heavy blooms.

• Pinching: When plants reach 12–16 inches tall, pinch out the main growing tip to encourage branching and increased flower production.

• Fertilizing: Feed with a low-nitrogen fertilizer throughout the growing season to encourage flowering rather than excessive foliage.

• Bloom Period: Expect blooms from midsummer until the first fall frost.

• Overwintering: In colder climates, dig tubers after frost blackens the foliage. Allow them to dry, then store in a cool, dry, frost-free place until spring.
