- Acaena splendens — A species of suffruticose perennial plant in the Acaena genus, native to the high mountainous zones of Chile and Argentina. This plant stands out for its exceptional aesthetics, being entirely covered by a dense indumentum of long, silky, appressed hairs, which give it an intensely glittering (shining) silvery appearance. This structural ecotype acts as an efficient thermal shield against severe nocturnal frosts and extreme ultraviolet radiation at high altitudes.
- Agastache cana — A species of perennial plants in the genus Agastache, native to the semi-arid mountainous regions of New Mexico and Texas (USA), characterized by small leaves with a strong fragrance reminiscent of bubblegum or licorice, and spiked inflorescences with intense rose-purple tubular flowers. Structurally, the plant features fine grayish hairs on its leaves (the epithet 'cana' meaning hoary or gray) and has an outstanding resistance to drought, being favored in xeric gardens.
- Ageratum corymbosum — A species of perennial herbaceous plant in the genus Ageratum, native to Mexico and the southern United States, characterized by corymbose inflorescences made of small, deep-blue or violet flowers. It is occasionally used in horticulture for its ability to attract pollinators and its superior resistance in arid climates compared to annual species.
- Kangaroo paw — A genus of herbaceous perennial plants, native to the arid regions of Southwestern Australia, belonging to the Haemodoraceae family. Commonly known as 'Kangaroo paw' due to the tubular, curved, and velvety hairy shape of its inflorescences, this structural plant develops long flowering stalks emerging from a rosette of sword-like leaves, being highly valued worldwide in xeriscaping and as a cut flower.
- Golden kangaroo paw — A rhizomatous perennial species of the Anigozanthos genus, remarkable for its bright golden-yellow inflorescences covered with dense yellow and red hairs. This structural plant grows on dry, sandy soils of Southwestern Australia, forming branched flower stalks that provide a stunning visual display during summer, being highly valued in dried floral arrangements due to its ability to retain intense color after cutting.
