latin: Malvae arbor. Flor. tot.
botanical: Alcea rosea L.
Suitable for eco printing and dyeing. Black mallow will leave some gorgeous purple-blue, violet prints on fabric. I only have used them in eco printing and can confirm that Mallow prints will last for a number of years, depending on light exposure and washing.
*use an iron mordant for deep to black prints
** use a standard mordant procedure for overall dye or print
*** only petals/flowers are used
Colour fastness: weak to medium (if a mordant is used and due to the presence of anthocyanin in the flowers)
