Plants recommendations for nursery bed

[24HoursFromTulseHill]

My DS's nursery has a narrow bed outside the front door that is very neglected.

I'm about to volunteer a day's labour along with doing a collection to buy some soil & plants.

Before I do this, what recommendations do you have for very, very low maintenance plants that will take minimal looking after? Because it's out the front by the car park it would just be staff looking after it, not something tne chidren can help with.

It's north east facing, pretty well sheltered and currently has 1 shrub, some daffodil bulbs and a handful of dandelions growing in it at the moment.
Approx 3 metres wide, 30cm high and 15 - 30cm wide (wavy edge).

Ponytail grass.

Fuchsias - they like shade, minimal maintenance, long flowering - choose some shorter upright varieties

Anemone Blanda - no maintenance, early spring flowering, weather resistant, gradually increase over the years, leaves not messy like daffodils and crocuses

I'd throw on a load of herb seeds. Thyme, chives, borage, that sort of thing.

Saxifrage (stays low, spring flowing and will creep over the wall a bit). Maybe a creeping phlox for the other end (late spring/early summer flowing). Both grow happily in poor soil. Neither will get out of control or too wood to walk past.
If you want complete low maintenance a variegated bugle (this might need cutting back as it grows and grows).

*wide, not wood

I'd also do herbs, just not borage as that is quite prickly. 3 chives, 3 rosemary, 3 thymes, and a few mints which i'd plant in large sunken plant pots to contain the roots. I'd include a creeping rosemary, and garlic chives, and different themes. Also maybe a sage, and some different oreganos

The only maintenance would be to cut back the oregano plants after flowering before the summer hols, cut back growth when you get back after summer and weed it. Should fill out nicely. And nobody will get poisoned if a leaf or two gets nibbled on.

Fill it with lavender? Caveat I'm not a gardener!

Ignore me - just googled lavender is toxic to cats and dogs. Not a good idea.

What about dwarf Hebes ? They need little to no maintenance and will be evergreen with early summer flowers.
