I live on a windy dry hilltop. Over the past few years I have been struggling with a large bed (of mostly thistles and weeds). I planted daylilies but now due to grass overtaking the bed must dig them out.

I was wondering if its ok to pop them into deep/large pots, will they grow in containers?

Also I am still struggling with the large dry hilltop bed, I am looking for something natural/wild and last summer added some large rocks and a few pieces of driftwood which really made it look a lot better.

I am now going to try planting some heather around the rocks (and maybe poppies or babybreath because they grow in the hot dry sun). I would appreciate any suggestions for my lonely hilltop!

I was also wondering about lavendar...

Daylilies are a pretty hardy bunch, and they might be happy in a pot during the summer, but I am fairly certain that they will not survive in a pot over winter in your 2B zone. The roots need to be snug in the ground to live through winter cold. Lavender is great in a dry, full sun location - two varieties that are the most winter hardy: Munstead and Hidcote. I have one of these two, don't remember which, and it has lived through many winters here, just outside Ottawa.
