Golden Thistle Yellow

Scolymus

Scolymus is a genus of annual, biennial or perennial, herbaceous plants that is assigned to the family Asteraceae, and can be found in Macaronesia, around the Mediterranean, and in the Middle East. All species are spiny, thistle-like in appearance, with flowerheads that consist of yellow ligulate florets, and canals that contain latex. It is sometimes called golden thistle or oyster thistle, and is known as سكوليمس (skwlyms) in Arabic and scolyme in French.

Thistle

Thistle is the popular name of a group of flowering plants characterised by leaves with sharp spikes on the margins, mostly in the family Asteraceae. Prickles can also occur all over the plant – on the stem, and on the flat parts of the leaves. These prickles protect the plant from herbivores. Typically, an involucre with a clasping shape, similar to a cup or urn, subtends each of a thistle's flower heads. The typically feathery pappus of a ripe thistle flower is known as thistle-down.

Yellow

Yellow is a color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575–585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths.
