Artemisia lactiflora, the white mugwort, is a species of flowering plant in the daisy family, native to western China. It is a vigorous clump-forming herbaceous perennial growing to 1.5m, with plumes of creamy-white flower heads appearing in summer and autumn above dark green leaves. This is the only artemisia which is cultivated as much for its flowers as for its foliage. Plants grown in poor dry soil are hardier and last longer than those grown in heavy, damp soil. The specific epithet lactiflora means "milk-white flowers". This plant has gained the Royal Horticultural Society's Award of Garden Merit.

Compounds documented for Artemisia lactiflora across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Artemisia lactiflora has left across the world's sequence archives.

The complete instruction manualArtemisia lactiflora carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

Where the DNA of Artemisia lactiflora was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
