Horsetail (equisetum) is a wonderful plant materiel to play with in Ikebana arrangements. With the help of an iron wire inserted into the cavity of the grass, it can be bended and twisted into any form.

For other arrangements using horsetail check this post from 2014 and this one from 2013 both in Turkish.
