Also, being an herbaceous perennial it should die down over winter and regrow and flower the following year for at least five years if given the correct growing conditions.
Does valerian require supports?
If grown in the right conditions, no, it should not require staking as its loose, billowing habit is part of the plant’s charm.
Is it good for pollinators?
The scented, tiny white or pink flowers attract butterflies and bees as well as other pollinating insects.

How to plant valerian
Plant in nutrient rich, reliably moist soil in full sun at the same level as the plant was growing in the pot. Water in well until plant has established.
How to care for valerian
Valerian grow best in soil that remains reliably moist and so, if growing in containers, you will need to make sure the plant is regularly watered.
Valerian likes nitrogen rich soil so, if growing in containers, give it a balanced nutrient liquid feed weekly during the summer to keep the plant looking healthy and to encourage continued flowering.
Cut herbaceous perennials down to ground level in autumn and collect seed of annuals late summer when the seed heads have turned brown, ready for sowing in spring. Alternatively scatter ripe seed heads onto damp soil in early autumn.
Does valerian spread?
It can self seed, so if you don’t want lots of seedlings around the border, simply cut back the flowered stems before the seed heads form.
How to keep it looking good
As an herbaceous perennial, it requires little or no pruning but responds well to being given a layer of mulch above it after cutting stems down to the ground in the autumn, followed by a top up mulch layer in the spring as the new shoots start to appear above soil.
For best results keep the plant well watered if planting in containers, or if planting in a border, plant in soil that stays reliably moist, but not water-logged.

Does valerian need deadheading?
Deadheading the plant as the flowers fade will promote a succession of new flowers during the summer months as well as stop the plant forming seed heads and self seeding around the borders.
Does it need pruning, and when should they be pruned?
Valerian is an herbaceous perennial and therefore does not need pruning other than cutting down flowered stems at the end of the growing season.
