Oxeye daisy is to many people the most typical of flowers. Like other members of the Daisy family, however, its flower-like part is in fact a capitulum that is comprised of hundreds of tiny flowers. The yellow part in the middle is densely packed with tiny disc florets, which have tubular corollas. They are surrounded by white ray-florets, which have tongue-like corollas. It is these petaloid flowers that shy lovers pick to get an answer to their question: she loves me, she loves me not… The way that the work is shared between the different flowers has been developed to a very advanced stage: the numerous disc florets have many functioning stamens and pistils, and the ray-florets, which have large corollas that are visible from a distance, advertise the capitula to passing would-be pollinator insects. The nectar is at the bottom of the tubular corolla and available only to those who have a proboscis: the pollen on the other hand is higher up in the corolla mouth and is thus available to non-specialised insects too.

A capitula’s inflorescence lasts almost a month and a dense stand of oxeye daisies will decorate a meadow for a very long time. Oxeye daisy meadows have decreased in number with the corresponding increase in intensive agriculture, but luckily it also thrives on sunny banks and in gardens, and it has been decorating crofts and manor houses since before the concept of gardens even existed. Apart from people, ox-eye daisy is also a delight to small insects, and e.g. day butterflies, small beetles and flower flies are all frequent visitors.

Ox-eye daisy can sometimes be confused with scentless mayweed (Tripleurospermum perforatum), although the latter has thin-lobed, dill-like leaves. Ox-eye daisy is the national flower of Latvia and provincial flower of Central Finland.

Mauranthemum paludosum

Mauranthemum paludosum (Leucanthemum paludosum)

NOT TRANSLATED YET. Yksivuotinen peikonkakkara on kukiltaan päivänkakkaraa muistuttava koristekasvi, jota saattaa löytyä luonnosta esim. multakasoilta läheltä puutarhaliikkeitä. Peikonkakkara on melko lyhyt (yleensä alle 20 cm) ja haarova. Lehdet ovat syvään hampaiset, lähes pariliuskaiset. Aidosti luonnonvaraisena peikonkakkaraa voi löytää Etelä-Euroopasta ja Pohjois-Afrikasta.

Shasta Daisy

Leucanthemum x superbum

NOT TRANSLATED YET. Isopäivänkakkara on päivänkakkaraa suuresti muistuttava koristekasvi, joka saattaa karata luontoomme ja säilyä siellä jonkin aikaa. Niin kuin nimikin sanoo, isopäivänkakkara on peruskakkaraa selvästi kookkaampi ja saattaa saavuttaa yli metrin korkeuden. Ehkä selkein erottava tekijä on ruusukelehdet tai niiden puutuminen. Päivänkakkaralla on talvehtiva ruusuke, jonka lehdet ovat lusikkamaisia. Isopäivänkakkaralla ei ole ruusuketta ja alimmatkin tyvilehdet ovat (kapean)soikeita.
