A close family member recently passed away. She was cremated and here was no funeral or memorial. I would like to acknowledge her passing beyond a card and telephone call (they live many states away). They are not 'cause' or 'church' people so a memorial contribution to an organization/church would not be meaningful to them. I was thinking of a gift certificate to a local gardening center so they could get a tree or shrub or something to plant in her memory. Never been in this situation before. Suggestions?
