Trifolium incarnatum, also known as crimson clover, is a fast‑growing annual clover with multiple practical and ornamental values. These flower seeds produce upright stems covered with soft green trifoliate leaves, crowned by striking elongated crimson‑red flower heads. The vivid bright red blooms attract bees, butterflies and various beneficial pollinators. Besides ornamental use in meadow layouts, it works efficiently as green manure crop, improving soil nitrogen content when tilled into soil. It adapts well to open sunny sites. Well‑drained loamy soil delivers best performance. Avoid permanently waterlogged ground. It needs little extra fertilizer. Allow some seed to ripen if you want natural self‑sowing for next‑year growth.
Planting Instructions Soil Preparation Choose full‑sun location. Ordinary loam soil is suitable. It tolerates slightly poor soil. Improve drainage for heavy clay soil.
