Lynn, your beds look gorgeous, as usual!
Evie, sounds like a lot of work, but you'll be so happy when it's done.
Have a long story for you here, but it's about semp beds, so bear with me.
Earlier this year I discovered there is a place in Wisconsin that sells (and is well known I guess) for her sempervivum and alpine plants. At that time I called her and we had a nice conversation. She told me that about 50 years ago she used to sell semps all over the world (without even having the use of the internet!
) She still sells plants and offers tours. She sent me her plant lists and some very nice pictures.
In May I took a day of vacation from work and went to see her (it's a several hundred mile drive). I can honestly say I was shocked - and not in a real good way. First of all, I was very surprised at her "beds". It's a very rocky area and rather than make raised beds, she cut the ground down and away from areas to create a huge raised bed. This "bed" was about 3 - 3-1/2 feet high. It's mostly large rocks. Then she covered the top of the rocks with thick black plastic, added a very (VERY) small amount of black dirt/compost and lots of pea sized pebbles - many years ago. After that she has never added anything as far as soil/fertilizer to the bed. She told me when the leaves fall off their trees and decompose, that is all that ever gets added. And that is what she plants in. Unfortunately I didn't take very many pictures, but wish I had taken more of the area as a whole. Anyway, it works well for her and the plants are quite healthy.
The part I was surprised about was that the black plastic was sticking out all over the place and you had to watch where you walked because there were plastic and hypertufa pots all over the place - every square inch of space was covered. She had created a very rough terrain but the plants thrived. She planted in the sides of the bed too. Unfortunately it was difficult to get a picture without black plastic in it. But here are some pictures.
She had beautiful combinations in pots, but some of the pots were 8-10" deep with maybe 2" of pebble/soil in the bottom so you could only see the plants from the top down.
She also had lots of crested plants, like this little arachoideum.
The part I was shocked at was that I saw a total of two plant labels the entire time I was there. Everything else was "from memory". Now I know some semps are very distinctive, BUT......
To show us how easy these plants are to care for and multiply, she showed us (I took my Mom & Dad along) an example. She pulled a plant out of the ground and literally threw it. Wherever it landed, it landed - she didn't even watch where it went. (I hope the people that purchase from her don't think they have accurately named plants.)
Anyway, the point of this long story is that beds come in all shapes, sizes, and types, and these are amazingly tough little plants!
