Q.Flower bed next to house

Zone 39110 | Anonymous added on February 23, 2020 | Answered

I live in zone 8 and wanted to use perennial flowers for the bed. My bed is about 30 feet wide and 4 to 6 feet deep due to irregular borders. My yard is very small. What should be the height of the tallest plant in back? Also, would ornamental grass be good to use in this bed? if so, which one is not invasive?

Of those mentioned, northern sea oats and purple millet can be invasive.
