Wildflower plugs to plant

The meadow is nicely stabilised as it is now 10 years old, but I am still gradually increasing the diversity of flowers - and am trying to work out the best planting schedule for different species.

I saw some Great Burnet growing wild in a nearby field last summer, which spurred me on to buy some plants. Today have planted out some plug plants (bought from the Trust for Conservation Volunteers, who have just closed their online shop) into pots. These will be planted into the meadow and surrounds in a few weeks time. I will be spraying small areas with Roundup to give somewhere for them to grow - but as  it is windy and there are showers coming through will have to wait for a dry and still day to do the spraying. Plantings have been:

To go in the boggy areas of long grass at the bottom of the meadow.

Hemp Agrimony (Eupatorium cannabinum) - 

To go in the wood:

Wild Primrose (Primula vulgaris)

Wood Avens (Geum urban)

To go in the field:

Wild Carrot (Daucus carota)

Common Valerian (Valeriana officinalis)

Great Burnet (Sanguisorba officials)
Meadow Clary (Salvia pratensis)

To go on the edges of a stony area:

Red Valerian (Centrranthus ruber)

The ground is too waterlogged to plant these out a present so I will grow them on a bit in pots (the mesh on top is to stop the chickens digging them up).
