This plant grows everywhere in my garden. Selfseeding a lot but easy to remove. So that's why it is welcome...growing in all conditions and with its typical spicy scent...filling lots of vases again and again. In Netherlands we call this Moederkruid (Mothersherb transl.) ..probably this name is given for its medical use during maternity.

'Flore Pleno' is a double-flowered variety. Unlike its single-flowered relative, this one does not self-seed enough to be invasive. It is relatively short-lived, but enough new plants grow from seed to always have a new plant or two in readiness for any that fail to survive.

It will grow in moderately dense shade, but will sprawl rather than growing upright.

Since it sets relatively few seed, its flowering season is very prolonged: mine bloom from early June through a killing frost in November, with a slight pause in mid-summer. The blooms are great in bouquets or dried for everlastings.
