Tall stems ( 50-100cm, 2-3 ft.) support large clusters of bright purple flowers in late spring, early summer.

For maximum freshness, please keep seed refrigerated in its original packaging until it is time to plant. Sow seed in containers in a cold frame, when ripe or in spring. Grow in fertile, well-drained soil in full sun. Moist, well-drained soil rich in organic matter will produce the best results. In regions where the winter lows are likely to dip below -10C, a heavy mulch should be applied.
