Scentless mayweed
Scentless mayweed; Scentless chamomile Harilik kesalill Tripleurospermum inodorum
Sea mayweed Rand-kesalill Matricaria maritima
The prettily flowering and long-lasting scentless mayweed is generally regarded as a field weed. The mayweed growing on the seashore is however considered to be a species of its own by botanists: sea mayweed
The mayweeds develop as annual or biennial plants and spreadi by seeds. The seeds can germinate for until up to 7 years in soil and if the soil surface is disturbed the mayweeds appear again; they like to grow without competitors in open spaces. They are held to be troublesome weeds because they use much water and minerals from the soil when they grow in a plant bed.
The stems of mayweed branch extensively and the feathery leaves remind of dill. The main stem as well as the side stems carry inflorescences and there are flowers to go around until snow comes. The large number of flowers in an inflorescence makes up to unbelievable numbers: the inflorescences of a single plant can create 50 000 to 1,5 million seeds… Some simply know how to be fertile.
