planting in joints of flagstone patio
Hi, after 3 months, I'm nearing completion of my 800 sq.ft. dry-laid flagstone patio. I'm in zone 6, specifically Philadelphia. In the past year, we've had 30" snowfalls, weeks of 100 degree heat, and weeks of rain - every extreme. That said, I've seen a lot of ideas for planting in the joints - irish moss, sedum, thyme, etc. - and I'm wondering what is the best bet to plant in the coming months for someone in my zone. My joints are about 1-2", for the most part.
There will be foot traffic and the area gets a lot of sun -- house on the west, shrubs on the right, no shade north or south. I'm not worried about bees - I welcome them. Any ideas on what to plant and when? Right now the whole thing is laid on a bed of about 4' sand, 4' gravel with not much of a downward slop until the bottom, where there will be car tracks and room for a car (I will use pea gravel in the joints here). Thanks.
