Gypsophila paniculata

Hi Pcw.
I've just purchased some bulbs and was wondering if you have any advice, such as planting times & width of plant?
I'm a beginner, so am clueless. Lol.
Thanks!
P.S. They' rhizomes, aren't they, not bulbs? :-\

Hi Mouldy,sorry only just seen your comment.
These should be fleshy roots,that go deep into the soil,not rhizomes that would normally spread outwards on or just beneath the surface.
If you bought bare rooted they should be able to be planted straight away,providing the ground isn't frozen or waterlogged.Or you could pot them up until you are ready.
These are ideal for planting where they can branch through other plants,or spread into a gap where earlier plants have died back/cut down.

Considering the weather's inability to make up it's mind, I think I'll opt for your suggestion of potting up, at this moment in time, Pcw.
The pack I bought contains 3 roots.
Hard to tell. The aeriated, dark yellow bag, with a sparse amount of what I take to be compost, is difficult to penetrate, but by touch, it seems you are spot on!
My intention is to place them at the back of the bed with Astilbe glut & Tricyrtis slightly forward & flanking the Gypso' on either side, which was why I enquired about the plant's width, as I didn't want to crowd it, but, as you've pointed out, it's happy to merge with other plants.
Thanks a lot for your time & advice, Pcw. I really appreciate it.

Astilbe and Tricyrtis would normally thrive on different soil to Gypsophila,moist soil,while Gypsophila would do well on poor dry soil once established.It could also be short lived on heavy soil.

I have an 'L' shaped strip, but turned 180° clockwise.
The short leg is S-facing, whilst the longer leg is W-facing.
The soil was quite dry S-f and slightly clayier W-f.
I was going to plant the Gypso' where the walls join.
Is that a bad idea, Pcw?

South and west facing should suit the Gypsophila,as plenty of sun and dry.It may not suit the other 2 though,the clay will bake solid in summer.

I'm planning on dense planting with mulching, too, plus regular watering, Pcw.
Any spaces, should any exist later, will be liberally sown.
I guess I'm more concerned with planting & settling perennials this year.
I'm not actually expecting any to appear this yr, regardless of what the labels promise, ergo, any that do will be a bonus.
I'm also preparing for the fact that some plants, although being sold this far north, are being done so on a speculative basis by companies, as they've nothing to lose. Lol.
