Ah @CheerBear I didn't know if it was a Dahlia or an Echinacea. Dahlias are very pretty. The Alyssum should not be any problem at all, just might need surface watering a bit more when it flowers. I fell in love with Alyssum in school, we used to have a class garden on the school grounds - years 1 to 7 - it was a set of display gardens.
One year we had Alyssum edging the oval garden with Lupins, I think, in the very middle, it was so pretty. I learned a great deal about gardening in those 7 years. I also had my own garden at home, mostly grew Carnations and Cornflowers with Alyssum edgings. I wanted to grow food plants but wasn't allowed, it had to be just for pleasure as dad had the big food garden.
Should have learnt more about self care from that restriction than I did, I think.
@Catcakes I too think magnolias are so beautiful, such a delightful perfume, I love them too. How lovely have the streets lined with them. @CheerBear
