Without going through details of all landscape-engineering drawings, it would be safe to say there are under 40 different species amongst smaller number of families.

It would almost seem a necessary love of some gardening on the personal side, for a landscape architect to always have that memory skill and keep alive the understanding how plants behave under certain environmental conditions. Do you folks dream in conceptual spaces, colours and then details of plants...?

I'm not much good at any 3-D art, so have great respect for interior designers, landscape architects, sculptors, etc.
