5 Seeds Showy Rattlebox Crotalaria spectabilis Golden Yellow Flowering Ornamental

Showy Rattlebox (Crotalaria spectabilis) is an annual flowering plant grown for its tall spikes of bright golden-yellow pea-like blooms that rise above blue-green foliage through the warm season. It brings bold vertical color and texture to beds, borders, and meadow-style plantings, and its striking flowers are followed by inflated seed pods that rattle when dry.
Grown as an ornamental in sunny gardens, Showy Rattlebox works well toward the back of a border or as a warm-season accent among other annuals and perennials. It grows quickly in warm weather and prefers consistent moisture while establishing; allow pods to mature on the plant if you wish to collect seed for the next season.
