Seedlings start flowering same year after sowing, in their fourth month. The growth of delphiniums halts, when seeds ripen, so inflorescences are best removed after the flowering is over. Delphiniums may flower repeatedly in autumn, if the spent blooms have been removed. Bear in mind that this wears the plant down, as it does not have time to set new buds, which may result in less than spectacular flowering next year.
