Crimson clover is rarely seen, but that is purely to do with the rarity of the species – its fantastic deep red elongated flowers could hardly go unnoticed. Crimson clover grows ferally across a large area of Europe. It is also cultivated, particularly in North America, as a fodder crop, to provide food for bees and to improve the soil. In Finland the plant is not really farmed agriculturally but it rather an ornamental or casual alien. Most often it appears amongst uncleaned lawn seed or maybe deliberately as part of a seed mix.

It is easy to differentiate crimson clover from other Finnish red-flowered species: its inflorescence is elongated while red clover’s (T. pratense) and zigzag clover’s (T. medium) is spherical. Other exotic clover species can sometimes be found growing in Finland, usually as aliens, and sometimes as fodder or fallow-field crops.

Reversed Clover

Trifolium resupinatum

NOT TRANSLATED YET. Välimeren seuduilta kotoisin oleva punakukkainen tuoksuapila on meillä vielä melko harvinainen tulokaslaji. (Muut punakukkaiset apilamme ovat metsä-, puna- ja veriapila.) Yksivuotinen tuoksuapila muistuttaa metsä- ja veriapilaa siinä, että niillä kaikilla on selvästi havaittava kukintoperä (puna-apilan kukinto on perätön ja tyvi tukilehdellinen). Tuoksuapilan kukinto on pallomainen tai hiukan litteä, mikä ominaisuus erottaa sen selvästi pitkäkukintoisesta veriapilasta. Metsäapilan lehdykät ovat soikeita, tuoksuapilan vastapuikeita. Ja tuoksuapila on nimensä mukaisesti hyvän tuoksuinen.
