I am not sure which one you are asking about, but either way...I don't know. I picked out three bags of wildflower seeds and planted them in the Spring. I fed a lot of the flowers to the tortoises and pulled out a lot because it was just too over grown.
Very beautiful turtle garden. When you look in your garden, and you can't see your box turtle, you did a good job.....so my friend at the rescue tells me. It's great, and I'm sure they feel very secure in there with plenty of places to hide.
It's treated 4"X4" (I think pine - it was cheaper!). I would not say it was too expensive, but for the look and sturdiness, it was worth the price. It's part of the Sulcata's pen so it had to be strong. I went down a few boards just so the Sulcata's would not break into the next yard.
