A grower asked if D. burmannii can be propagated vegetatively or produces plantlets, noting sequential flowering.
D. burmannii (and D. indica) are annuals reproducing only by seed. Flowers open one per day on a raceme; most self-pollinate. You can boost seed set by brushing floral parts. Leaf/root cuttings fail; roots are too tiny. Collect seed by tapping dried stalks over white paper; sow immediately.
Good Growing!
