In its first year, it forms a basal rosette; in the second year, it produces flowering stems and sets fruit.

It has been present in the Botanic Garden since its early days, thanks to seed collection carried out at the Coll de S\u00f3ller in 1985 by the local botanist Jeroni Orell Casasnovas. Since then, the species reappears each year in the Garden, almost spontaneously, choosing where it wants to grow. It blooms from June and produces thousands of tiny seeds\u20141,000 of which weigh no more than 0.1 grams. It is a striking plant and, due to its rarity in the Islands, enjoys the unique privilege of establishing itself every two years in different corners of the Botanic Garden.<\/p><p>Known as <em>blat\u00e0ria<\/em> in Catalan or <em>moth mullein<\/em> in English (literally \u201ccockroach mullein\u201d from Spanish <em>gordolobo polillero<\/em>), it originates from Eurasia and North Africa and has been introduced in various regions around the world. It can grow up to 1.2 meters tall and is characterized by completely hairless basal leaves and lower stem. The flowers are solitary on each bract, showy and yellow, with five dimorphic stamens: some have purple hairs on the upper third, while others have purplish hairs on the lower two-thirds\u2014features that help distinguish it from other <em>Verbascum<\/em> species. When it fruits, it forms a round capsule containing many small, rough seeds.<\/p><p>Studies on its metabolic compounds have identified 17 secondary metabolites. The plant extract shows antioxidant activity, suggesting significant potential health benefits. In fact, the species name <em>blattaria<\/em> comes from the Latin word <em>blatta<\/em> (cockroach), as the plant was once believed to repel cockroaches and other insects.<\/p><p>Other <em>Verbascum<\/em> species, locally known in the Balearic Islands as <em>trepons<\/em>, can also be found. They are distinguishable by their basal leaves, flower arrangement, and calyx shape, though hybrid forms with intermediate traits may occasionally appear.<\/p><p><\/p>","protected":false},"excerpt":{"rendered":"<p>PLANTA DEL MES &#8211; JUNY 2025 CAT: trep\u00f3, blat\u00e0ria, llepassera borda, herba de les arnes ES: Gordolobo, polillera, sabonera\u2026 FAMILY: Scrophulariaceae Synonyms: DISTRIBUTION: Native from Northern Europe to Afghanistan and Northwest Africa.
