I've never seen a low growing pink gypsophila - pity you didn't take a photo. Google only shows white tall ones and I'm wondering if the attendant was right? Hope someone else will have a better answer.

Gypsophila repens Dorothy Teacher is a low growing pale pink one, but there are other pink repens forms.
G. petraea has a very pale pink form,so I am told, but never seen it.

It used to be a stalwart of the rock garden and troughs where I grew up, gipsophila repens 'Rosea'. Not such a favourite now, so unfortunately not widely stocked, or its named forms. Ousted in favour of longer flowering, larger flowered more 'showy' plants. I'll have a hunt for it from my suppliers and see if mail order's a possibility

Wow, this is a fantastic site. I used to have an old uncle with an allotment. He grew a tall white one and he always called it Gipsy Filly. Bless 'im. He had a little privy in the allotment that was just a long drop into the river.

Just been splitting up a Gypsophila cerastioides, which is a lovely dwarf plant, but it really does not like my garden which is sad.
