Sometimes the most striking arrangement is the simplest: a mass of one flower in one vase. No filler, no foliage, no fuss. Single-variety arrangements let the flower itself be the statement.
Dahlias — Especially large dinner plate types. Six to twelve stems in a low bowl.
Tulips — A dozen in a glass vase, letting them bend and sway naturally.
Peonies — Three to five stems in a ceramic vessel is enough.
Sunflowers — A tall bunch in a stoneware pitcher.
Daffodils — A generous bunch in a mason jar captures spring.
Ranunculus — Tight bunches of one color in small vases.
Use enough stems to create fullness—a single-variety arrangement that looks sparse loses the effect. Stick to one color for maximum impact, or use a gradient from light to dark. Choose a vase that complements rather than competes with the flowers.
