Apr 12, 2024 · Dandelion Stems. Dandelions produce flower stems from the center of their crowns. These stems are hollow, leafless, unbranched, and generally 4 to 18 inches in height, though they may reach slightly higher, especially in full shade. The stems may be pure light green, especially in shady areas, or be tinged with red.
Dandelions are often considered a pesky weed in Canada and the U.S. yet European and Asian nations have greatly benefited for years from the incredible nutritional value that this weed contains. They are a rich source of vitamins, minerals and it even has antioxidants. For example, one cup of raw dandelion greens contains 112% of your daily ...

BSBI Handbook no. 9, Dandelions of the British Isles (Dudman & Richards 1997) was the standard source of reference, but John Richards, co-author, has now published a completely revised edition: BSBI Handbook no. 23 is the Field Handbook to British and Irish Dandelions. John has also prepared a selection of online dandelion species accounts, startin...
Our free Dandelion ID online workshop, led by Handbook author John Richards, was held on 25th April 2021; the webinar was recorded and the video is available here on the BSBI YouTube channel. It's aimed at intermediate level botanists - if you are brand new to dandelion ID, try Josh Styles' Intro to Dandelions webinar first: it helps you put your d...
Together with Hieracium (hawkweeds) and Rubus (blackberries), Taraxacum is probably the most challenging genus that British and Irish botanists encounter. Tim Rich has set out a few Taraxacum dos and don'ts to help you get started, but if you're only just beginning to identify wild plants, we'd suggest that you get some of the more user-friendly ge...
By its nature, the sectional division of Taraxacumproduces much more “fuzzy” categories than the species or genus, hence the sections must be keyed out using as many characters as possible, including ecological ones. Indeed, ecological characters are very significant for, given the habitat or locality, one can expect to find members of certain sect...
For anyone who is serious about identifying dandelions, there is no substitute for developing a comprehensive herbarium of well-preserved material named by a recognised authority who is going to want to see specimens that have been carefully selected in the field and pressed for later reference. A presentation given by Tim Rich at the BSBI Recorder...
Digital images to accompany specimens can markedly enhance their value as characters lost or obscured by pressing can be assessed and pictures should be taken at the time of collection. Particularly useful are pictures of involucres in late bud, the attitude of the ligules underneath, and the colour of the outside of the petiole. Images should be n...
While you're getting started with dandelion identification, there are groups and individuals on social media who will help. 1. On Twitter, try Joshua Styles or Alex Prendergast. Or share your photos during Wild Flower Hour and add the #wildflowerID hashtag if you'd like some help. Take a look at some of the dandelion photos shared during Wild Flowe...
- Common Dandelion. When most people in the United States think of the dandelion, it is the Common Dandelion that comes to mind. This plant grows in sunny areas and blooms from April to September.
- Red Seed Dandelion. The main difference between the Red Seed Dandelion and the Common Dandelion is the shape of the leaves and the color of the seeds.
- California Dandelion. The California Dandelion is considered an endangered species of dandelion that is native to the Northern part of the United States.
- Yellow Desert Dandelion. The Yellow Desert Dandelion grows throughout the deserts and arid areas of the Pacific Northwest. This plant grows between 4 and 14 inches tall with 3 to 5 inch leaves.
The common dandelion is actually a variety of forms or 'microspecies' and there are also a number of other dandelion species, so identification can be tricky. Nevertheless, look for the familiar yellow flower heads displaying closely packed florets (tiny flowers). The leaves of the common dandelion are lobed and spoon-shaped, and the stem ...
Seedheads are globe-like (‘dandelion clocks’), composed of many silvery seed-bearing structures that disperse in the wind. Evergreen rosette of leaves, growing from a main taproot. The rosette is typically 15-30cm (6-12in) wide and is often flat, especially in lawns, but leaves can grow upwards if allowed. Leaves are long, narrow and often ...
