I suppose it could be A N Other cissus, there are lots, I don't know any of them
is C. antarctica a house plant?
with a name like that it ought to be hardy but are the Cissus hardy?
The leaves don't look right to me but Ladybird's point about not looking its best might explain that.
It's not a plant I know Ladybird but I had a look and again the flowers look similar but not the leaves.
The last one is Phormium tenax
That's disgraceful aym. I hope it turns out to be something really worth having.
those buds are distinctive and look very familiar, I hope someone will ID it before I have to think too much
do you think the first is a shrub or a hardy (or not) perennial aym?
bulbs need feeding in the foliage stage GD which is mostly after flowering.Though with alliums this is not the case
Try some and see.
This is the climax of growth, everything should be overflowing.
I fear it may be 'stop digging and dancing and kicking over old motorcycles'
