A garden weed is a plant that grows in the ‘wrong place’.
From self sown seeds I have Valerian growing in walls and cracks in pavements that despite the colour at this time of year are weeds. I must get them out before they seed and invade the few remaining gardens in our road that have not already received free plants from the overgrown Vicarage garden.
Facts about Valerian
- When you hear it is called Jupiter’s beard and that it has fragrant, scarlet to red or white flowers growing in dense clusters on 3-foot stems you may start to like the plant.
- They begin blooming in spring and continue over a long period if old flowering stems are removed but do not grow well if the soil is too rich.
- If flowering stops due to hot summer weather cut plants back by about a half to promote another round of bloom in late summer.
- This plant is best when massed and is often naturalized along old walls and rocky outcrops.
- Valerian (Centranthus) makes a long-lasting cut flower and is a good plant to supply butterflies with nectar.
- Centranthus rubervalerian alba has white flowers, coccineus has deep red flowers and roseus bears rose-colored flowers (no surprise with the names then).
