This week, as part of Mental Health Awareness Week, we have picked our top herbaceous choices to create a calm blue display in your garden. At this time of year the herbaceous border comes into its own, bursting into life and overflowing with colour. These plants will look great this Summer and will create comeback colour, as they will thrive again next year. If a trip to the garden centre sounds more stressful than calming at the time, then remember you can also shop with us online and get plants delivered directly to your door.
