Briefly, in Ideas Genie, think of Plants and Specimens like this.
1) Plants:
A Plant (profile) is where you define the name of the plant, its properties (height, flowering time, colour etc and many more etc's) its Care requirements (propagation details, seed sowing time, when to divide, when to fertilise etc and again more etc's)
You can link photos to plants. You can link plants to garden areas.
2) Specimens:
When you go out and buy a plant, or propagate (grow from seed, divisions) then those tangible and living plants are known as Specimens.
In Ideas Genie, you create specimen profiles.
You can enter things like Supplier, date purchased, propagation method, location (e.g. in the garden).
You then proceed to record events in the lifetime of your specimens:
Example:
a) Date seed sown
b) Date Germinated
c) Date re-potted
d) Date planted etc and as many more etc's as you wish (you defined the Event names - in this example a, b, c, d.
You can link specimens to photos and to garden areas (location)
Entering Specimen profiles details is optional in Ideas Genie. Some users just create Plant Profiles and link photos to plant names and link plants to gardens.
Divisions:
Some Plant genera are classified in Divisions, or Classifications.
The best known example is Rosa.
Hybrid Teas
Floribunda
Climbers and Ramblers
Patio
Damask
etc and many etcetras!
Other commonly grown Genera examples with divisions are:
Dahlia,Iris, Lilium, Clematis, Hydrangea, Rhododendron and so on.
