Sweet Alyssum (Lobularia maritima)
Most other plants are not flowering yet but it is worth to have a look every other week as more and more plants will come into flower now.

The perennial flower meadows are a bit slow growing and unfortunately some have unwanted weed growth.

But if you look closer you can find young plants of Ox-eye Daisy (Leucanthemum vulgare), Black Knapweed (Centaurea nigra), Yarrow (Achillea millefolium), Birdsfood Trefoil (Lotus corniculatus) and other nice meadow plants growing in the perennial flower meadows.
