What's hot and what's not this spring

Unfortunately I've been banned from talking about anything of any importance for a little while, so until the ban ends, I've decided to make myself useful and on a monthly basis sum up the best plant activity to be found at the plant nursery. These are all the plants that have brought me joy and brightened my day. They might also influence planting plans if you are looking for a plant to bring colour and interest during a particular month.
