Wonder, is that an air conditioning unit next to your hosta? Is that screen an air intake or output? (my husband would have a COW if I planted ANYTHING next to the A/C unit, as it would restrict its efficiency), so I'm inclined to agree with Sue.
P.S.: Why, oh, why is the best place to put equipment (generator, A/C unit, etc.) in my prime garden space ?! Inquiring minds just want to know !
