This is for my house, I want to put something ina bed in front of a bay window. The bed is about 7ft wide by 3 feet deep. I would like something for the center as a focal point as I have the surrounding area designed. I would like something about 2-3.5 ft tall and would love showy flowers as this will be a focal point of this bed. The area is mostly sunny with some shade in later part of the day. Soil is well drained, and can be easily ammended. I would also like something that blooms for a long time. I am in zone 7. What do you guys like and what do you put in your beds....I would like roses but the wife doesn't want roses?? No idea why....whuddya got?
