Hows about a picture of her favorite son on his favorite bike? Get a proper frame made for it. Im sure she would love it!!
Buy her a youngish tree. Bound to find one to fit your budget. Then she can watch it grow year after year and think of dutiful son. If it's a fruit tree, she can even have something to eat from it after a couple of years.
I had a Hawk flying experience day at the Hawk Conservancy near Andover on the A303. You could both go and have a truly humbling and memorable experience followed by lunch. She will appreciate a day with her little boy.
if she's anything like mine she still up for a bit of gardening? these are great for a bit of pruning :- Felco FEL2 Model 2 Original Secateurs: Amazon.co.uk: Garden & Outdoors

Take her out shopping - London, bath, somewhere with culture and nice shops. She can choose what she-d like and gets to spend time with you. Nice lunch as part of the day
The Ritz is not quite as great as you'd imagine, you can get a room for £400 a night if you ask and dinner is better next door at the Wolseley (IMHO), you don't need a tie and can wear jeans at the Wolseley too. The Ritz afternoon tea is however worth it or Langhams or the Savoy. There was a recent offer of lunch at the Dorchester for £30 which is mega value, Lastminute.com I think. She'd love any of these as they are very memorable.
You ain't kidding. I've worked on the air conditioning there and believe me, behind the scenes it's a craphole.
But the guests don't see that and it is a very old building. Last time I stayed it was value for money I felt, but the Dorchester is better to stay in.
I think if you're an outsider, especially a foreigner, then something like tea at the Ritz would be thoroughly enjoyable and different enough to be entertaining. But my mum's a Londoner and I really don't think she'd find it all that appealing. I doubt very much she'd see the attraction in paying a fortune for a cuppa.
