Packera dubia
species of plant
Packera dubia (synonym Packera tomentosa), often known by the name woolly ragwort, is a perennial species of flowering plant in the Asteraceae family. It is native to the southeastern United States, primarily to the coastal plain but extending into some areas inland and is common throughout its range, where it typically inhabits open, sandy areas and granitic outcrops. This species produces a head of yellow flowers in late spring. Its seeds have been shown to vary in mass within a single flower head as an adaptation to improve dispersal in disturbed habitats.
Description
This plant has bright yellow flower heads with relatively small, narrow ray petals and a large central yellow disk composed of disc florets. There are around 10-13 petals on each flower head and 50-60 disc florets making up the center of the flower. These plants do not typically grow to be taller than two feet and span from 30–60 cm (1–2 ft) in height. They have leaves that grow around the base of the plant that are thin and covered with small hairs. The basal leaves are long and leaf size decreases higher up the stem. Packera dubia leaves vary in leaf margins and are either subentire, crenate, or serrate-dentate.
The public source identifies “Packera dubia” as species of plant. This brief keeps that definition visible, then builds a research path around Packera, dubia and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Packera dubia”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q15579072. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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
