[13] [14] [15] According to both the Integrated Taxonomic Information System (ITIS) or the National Plant Germplasm System (NPGS), H. lanatum and H. maximum are synonyms for H. sphondylium subsp. montanum, [16] [17] a name proposed by Brummitt in 1971.
A giant hogweed plant usually produces a flowering stalk in 3–5 years, [2] [14] but plants may take up to eight years to flower if conditions are unfavourable. In the Czech Republic, a single plant reached twelve years old before flowering. [15] In any case, when the plant finally flowers, it does so between June and July (in the northern ...

Roots of older plants are far stronger and more bitter than those of younger plants. [citation needed] Osha plants form large clumps over time, and can grow to be very large. In areas of New Mexico, Colorado, and Utah, osha can reach heights of 6 to 7 feet and produce circular colonies with dozens of root crowns growing from a central root mass.

Almost every widely cultivated plant of this group is a considered useful as a companion plant. One reason is that the tiny flowers, clustered into umbels, are well suited for ladybugs, parasitic wasps, and predatory flies, which drink nectar when not reproducing. [15] They then prey upon insect pests on nearby plants.
