Gap in my clay border
I planted some mixed Gaillardia as part of a border in front of my back hedge but they all seem to have died.
The soil is clay although I'm working at it to improve the soil. I'm going to have to fill in the gap with something I can buy locally from a nursery.
The question is what? It's about a 4 metre gap. I've got coreopsis (now budding up nicely) and penstemons in the rest of the border so something that would complement them. The whole border is about 21 metres long. I'm not fussy about the colour at this stage and the only flowers that I wouldn't like to have there are geraniums. Something between about 50 and 100cm in height would suit the area and that will flower this year.
Any suggestions please? I don't want to go "blind" to the nursery otherwise I'll end up getting something unsuitable and also spending too much money (again )
