I've seen some roses - climbing roses look nice with a hedge of daffodils.

Daffodils also look great if planted under a tree or along with grasses due to the fact that the flowering is short, and their leaves turn yellow easily.

Daylilies are often used with daffodils. Their strappy foliage hides the dying foliage of the daffs.

I also like perennial geraniums with flowering bulbs. As it starts to spread it will hide yellowing foliage. Catmint is another good perennial for this.

I don't know, but I'm going to find out. For the first time ever, I've shifted some daff bulbs into my perennial garden.

It's in full sun, and the plants that are in there (liatris, heuchera, daylilies, lilies, coneflower, and one precious agastache) fluff up pretty seriously, pretty soon. They also suck up water pretty fiercely.

So the daffs and some tulips went in and will be there all summer and all winter, and I hope to get action next spring!
