A: As with all thistles, seed heads are a collection of florets, and each seed is attached to a pappus which allows it to be blown in the wind. When growing under good conditions, the flowering plant can get well over 1 m in height and takes up a lot of space in pasture due to its branching growth habit.

Q: What does Scottish thistle taste like?
A: Taste. I describe the taste of the root as bland slightly sweet, the stem as fresh and bitter (far nicer than burdock stem which I find way too astringent), leaves are more bland than the stem, this is because usually plants with spikes don’t also need a strong taste to deter predators.
