My mother passed away a little over a year ago and told me before she died that she wanted to be cremated and her ashes spread in a garden as she loved flowers, plants, shrubs and practically anything that grows in soil. She was far happier working in a garden than most folks would be going out to dinner and taking in a movie.
I found a church close by that had a memory garden and after getting consent, even though she wasn't a member of the church, from it's pastor scattered her cremains in the garden.
Last week after having a granite marker made I placed it in the garden where her ashes were spread.
I figured it was the least I could do in remembrance for someone who had sat by my bedside all night when I was a kid suffering with asthma, sacrificed to buy me a new bike for Christmas, had my Dad take and drive hot lunches to school which didn't have a cafeteria, lying awake half the night till I came in from partying, walked 5 miles to the school, at times in shoulder and waste deep water, minutes after a category 3 hurricane had passed over while worrying about our safety. These and for a thousand other things she did for my 2 brothers and me before she passed away.
She also said and did a few funny things, such as when she told me she didn't know that a tin plate would sparkle when heating something in a microwave oven and backing over her neighbor's (a deputy sheriff ) mail box so often that he got disgusted and moved it 50 feet away.
After hearing of the service station sniper killings a few years ago, she cautioned me every time I went to see her to be careful when filling up, as gas stations are a dangerous place to be around. (at almost 4 bucks a gallon they sure are)
If you are lucky and still have your Mom, I would suggest that you give her a big hug and thank her for all that she has done for you because when she's gone it'll be to late, as you're going to miss her.
