While we were at Wakehurst place a few weeks ago, my Mum was very drawn to the International Garden Photographer of the year exhibit, and if you want some excellent garden photography to put on your walls, check out the igpoty website (no this photo isn't one from the website, it's one of mine, - maybe in the future i'll enter!)
How about taking your Mum to a Garden on March 14th? The following gardens have free entry for Mums on Mothers Day - Painshill Park & Savill Garden
Or if you were to treat your mum to RHS membership, she'd have free entrance to Wisley, Hyde Hall, Rosemoor and Harlow Carr gardens for a whole year
If you like the idea of spending lunch or teatime with Mum there is an excellent cafe at Polesden Lacey or try the Conservatory Restuarant at RHS Wisley These are likely to be busy, so get there early & leave time to have a long brisk walk, then you'll deserve lunch.
If you want to spend a day with your Mum later in the year, why not book a day at a flower show. Last year we took M.i.l (and F.i.l) to the NEC at Birmingham and took Mum & Dad to Hampton Court Flower show, and had 2 fabulous days out at very different shows. Tickets are already available online for all the shows, - if your budget won't stretch to a full day, there are afternoon tickets available for most of the shows from 3.00pm
My personal favourite would be a plant for the garden or a bunch of English grown flowers like these
Or you could buy your Mum Plantpassion email advice. so that she can ask questions of an expert all year round.
Any other suggestions for a garden loving mum?
