That terra cotta pipe is awesome, Terri! I can see it half buried in another larger pot, with something trailing over its edge.....
Lyn thanks for that video. Originally the little slate pieces were slanted much more obliquely than almost parallel, but as things occurred to the bed I kept having to reposition them. I may play with it more but I like them for their visual appeal even if there is no actual crevice garden happening (though who knows how it will evolve??)
Greg, LOL! I need more rocks, period. I've used every one that was to hand! and that pea gravel mostly goes as mulch in pots.... So, yepper, moar rocks.
