Source-derived summary

Lactuca tatarica, known as blue lettuce, is a Eurasian flowering plant in the tribe Cichorieae within the family Asteraceae. It is widespread across much of Europe and Asia.

Lactuca tatarica is a herb up to 60 cm (2 feet) tall with a large taproot. Most of the leaves are near the base of the plant and are larger than leaves higher up the stem. Each flower head has about 20 blue or purple (rarely white) ray flowers and no disc flowers.

Some authors have placed the North American species Lactuca pulchella as a subspecies or variety of a broader concept of Lactuca tatarica, while others consider L. tatarica to occur only in Europe and Asia. Lactuca tatarica (with L. pulchella and others) is commonly separated into the genus Mulgedium, as Mulgedium tatarica.

Editorial summary

“Lactuca tatarica” enters the record as species of plant. Crown Archives preserves that source wording while asking what Lactuca, tatarica and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 132-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Lactuca, tatarica and species.
Editorial analysis

Why this record matters

“Lactuca tatarica” is worth following because a concise public description often conceals a longer documentary argument. Here, Lactuca, tatarica and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 17, 2025. The linked authority identifier is Q2395449. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
