Helianthemum salicifolium is an appressed-hairy annual plant that reaches up to 10-35 cm long with erect or ascending stems, branching mainly from the base. Flowers are with tomentose sepals with thick prominent nerves and yellow petals, which equal the sepals and are produced solitary and axillary. These small wildflowers were spotted in a prairie in Volos city, Greece.
Helianthemum salicifolium and other annual species of this genus, growing in the steppes and deserts of the Old World, are ephemerals. They manage to go through the entire development cycle - from germination of seeds to their ripening - in just a few weeks, before the onset of summer heat and drought. These plants have one or more generations per year, growing only during the periods with suitable conditions (for example, when adequate moisture is available) and passing the unfavorable periods in the form of seeds.
