We loved this beautiful colour form of wallflower in our trials in spring 2018, so perfectly picking up on many of our favourite tulip colours. It matches the double, glossy Tulip ‘Antraciet’, and is beautiful in contrast to scented, towering ‘Ballerina’. It’s a great new addition to the wallflower clan.
