Lavanda: By the way ... you are not a simpleton and I am so not good at explaining things so I hope I made sense in my first post.
The plant database just takes getting used to; you'll get it ... and if you ever have any difficulty, don't hesitate to ask. ATP is very user friendly, there are so many wonderful folks here, always willing to help! Sometimes the scientific names and stuff are way over my head and sometimes I forget something I used to know so I'm very glad that wonderful database moderators are always around to offer assistance!
