Oh dys, I had the most beautiful ice plants 2 years ago, just ask shewolf.
I have this planter that about, um, 15 or 18 feet long, and 4 feet wide, and just 4 ice plants ended up filling up most of it, and cascading to the ground, over three feet down.
I just loved coming home in the evening and seeing hundreds of bees crawling all over it. There was a lizard that lived in their too.
The flowers where wonderful little stars of magenta and yellow.
Then, last summer was extra hot....
The planter was made of sandstone, and it literally baked the roots. They needed some water of course, but I think that just steamed the roots. This year the ice plants grandbabies are going to grow along the east side of the porch steps. They'll be happy there.
Right now my tuplips are just starting to decide to send their flower stalks up, I'm hoping to have some blooms by the weekend.
