Short squat window box summer bedding plants
I have several large window boxes outside my kitchen that receive good sun all morning until mid afternoon. At the moment I have pansies in, but am looking for some ideas for summer bedding plants.
Last year I placed in the usual suspects, upright Petunias, trailing Lobelia, Busy Lizzys and Begonia. I have a watering system that waters daily and feed with Miracle grow once a week and they tend to grow well - too well! The Petunia and Lobelia go bonkers and soon end up flopping over the sides leaving a bald look from the top and look a bit of a mess. They tend to smother the Busy Lizzies and Begonia.
In addition to this, I have previously tried a window and some pots just with Busy Lizzies and Begonia. Not sure what I do wrong, but they often have what I'd describe a mushy flowers - soon looking soft and sticking to the leaves. So I've never really been a fan.
What summer bedding plants could I consider? I'm after colour and nothing to tall or rampant. Something that can look neat and fairly compact.
