I sent this in cultivation forum. Can someone confirm species,cultivar-Thanks!

There are two from cultivation requirement forum and one new added to identify. Great to be able to ask people who know! I have labeled one Arabis alpina ssp.causica 'snow cap' but am unsure of species and cultivar. The Phlox may be subulata but needs closest cultivar in your opinions. The Armeria is probably caespitosa but was meant to be pink according to label and came out white(could have been bad labelling). Can someone name the closest variety/cultivar for this too.

Many Thanks! see below:

David,  I can't help you on the first two pictures, but the armeria looks like A. maritima 'Alba'.  A. caespitosa is now an invalid name, and should instead be A. juniperifolia.  However, your plant looks like neither of those, and much more like the A. m. 'Alba' I am growing in my garden.

Armeria juniperifolia and its white form are stemless plants to all intents and purposes, very tight and compact.
