Cemetery …I’m Unable to Care for Flowers

Question

I am 82, in Ohio, and want to have blooming flowers at my husband’s grave. It’s sunny all day. I’m unable to water them. So when I plant them, they will get no water except rain. I do mulch them. They wither and usually die. I really need suggestions what I can plant to tolerate no care and hot sun situation.
Thank you.
