I'm not sure how costly it is 5LM. I was just impressed with the pictures she showed me. Given that they're high end landscapers, I trusted their judgement. With the natural flower beds going down the sides, I thought it looked very good! My boyfriend and I took a very quick look at artificial grass a few weeks ago. It's changed a lot over the years. It looks quite natural! I would think it might be a bit pricey and I've no idea about the longevity of it. I just love the idea of not reseeding every bloody YEAR!!!!!
