Hoop-Petticoat Daffodil Help please

RE: Bulbocodium Hybrid Narcissus, Hoop-Petticoat Daffodil
I bought lots of these bulbs from TM last year thinking they would be flowering bulbs - when I went to pick them up they were tiny tiny offsets with thin almost hair like leaves. The seller said they would probably flower this year!
Anyway, I paid and brought them home - potted them up and . nothing! They haven't died down, grown, let alone flowered; I don't know whether to keep watering them, feed them, dry them out, plead with them to grow . what?
I have some popped in with some annuals in pots and they are the same, although they get more water than the others that are just on their own in the pot. They aren't overcrowded and I think I have them at the correct depth.

SO, any ideas of what I should do? I'd be grateful for any ideas and input.
TIA

I mass plant mine along the front of borders and in pots. They have fine foliage and can be variable with flowering - some years I get blooms up till Christmas, other years next to nothing. I think I've seen three or four this season - pathetic reward, so I'm feeding them heavily and hoping for better next year. I' wouldn't toss them out, but you might have less disappointment by just leaving them to it. They're so pretty when they do behave for us!

Thank you, we are still trying to get our garden back after the Chch eq's totally devastated our garden and lawns, so there isn't a lot of space that's 'ready' to play with as far as planting goes. It's interesting what you say about them not performing very well though - now I know it's not necessarily 'me' and they are just a bit tricky I can just feed and ignore them.
How deep have you got yours planted?

Daffs can sulk sometimes and take a season to throw a flower. Plant your bulbs 3 depths the size of the bulb

The best display I ever saw was a row of these was under a feijoa hedge - on the street side. I complimented the owner on them and she told me she'd just tossed a handful of bulbs along one edge and they did so well she added a few each year till she'd done the length of the hedge. No digging, no feeding, no watering - and these displayed beautifully every year - which was why I put some in, they were so pretty. But I've never had the same success. I do have a lot of bulbs now though, they may not bloom reliably for me, but they make lots of babies. Wish my saffron did the same, lol!
