  • notes   Slo.: rožlin, slezova vrtnica - syn.: Althaea rosea (L.) Cav., Alcea ficifolia L., Althaea ficifolia (L.) Cav.. - Habitat: On the edge of an abandoned garden; also outside it between the gravel path and the garden wall, ruderal ground, once cultivated or escaped from cultivation; flat terrain, open, mostly sunny, dry location; elevation 17 m (55 feet), average precipitations ~ 950 mm/year, average temperature 13-15 deg C, Mediterranean phytogeographical region. - Substratum: sandy soil. - Comment on Flick album Alcea rosea: Today, the most well-known forms of Alcea rosea are hybrids and other cultivated taxa in horticulture. Plants blooming in various colors are available on the market, ranging from small varieties to those 2.5 m tall. Interestingly, its native range seems small and uncertain. EURO+MED (Ref.: ) identifies it as covering a small area on the western Balkan Peninsula, in present-day Montenegro. However, POWO (Ref.: ) states Turkey as its native range. In both cases, it is a small region compared to today's distribution range. Due to its stature, showy appearance, large, brightly colored flowers, and a long bloom period from June to August, the plant gained popularity in horticulture long ago. It is now cultivated in gardens worldwide. Often, it escapes gardens and grows, at least temporarily, sub-spontaneously in the wild; however, it is still almost always found near human settlements. - The flowers of Alcea rosea are ecologically important for a variety of pollinators. They are crucial for at least four species of wild bees, as the nectar from this taxon is essential for their survival. Additionally, the plant is considered medicinal and is used in some countries as an antitussive (quiet cough by blocking the cough reflex); however, it is generally regarded as poisonous. - Ref.: (1) T.
