A street side garden is about 60 feet long and 10-15 feet wide filled almost solidly with a big old hostas. They've been there for decades and the bed has been diversified under our tutelage, but there are still a lot of hosta, all the same, some big old plain, tough variety. They've suffered a bit after the removal of some dying spruces and white ashes exposed them to a lot more sunlight although this image doesn't show that. But what with all the rain this June (10.75 inches total, 2.5 times average), and cool weather, the bed is doing just fine so far, and just now it displays a sea of blue flowers that is quite spectacular even when just getting going. Nothing wrong with some massed, if not massive, plantings.
