just curious of any information on these plants, thought they all seem to be living just fine on my window sill. below is an optunia, any more detail on the name i do not know. next is a hawthoria attenuata caespitosa, or zebra plant. last is a pachyphytum oviferum, or moonstones. i also owned a kalanchoe thyrsiflora, or paddle plant. but unfortunatly i was especially new to succulents and did every single thing i could have done wrong. just this week i found a book that told me this, a few months too late! its a shame, it was beautiful.
