It was discussed with Dave some time back about maybe merging the Jovibarba with the Sempervivum database. It was decided that we should leave it as is, in case the botanists change their minds again. At some point in time they may be merged. Not sure?
I used the Plant Database and typed in heuffelii lemon sky. Comes right up.
I used the Jovibarba database typing in heuffelii lemon sky and then tried just Lemon Sky. Both ways it comes up with the entry.
