Tall bunches
Normally 30g per bunch with yellow, pale yellow, apricot, coral and antique pink being 20g due mainly to their thinner stems
Approximately 10 stems per bunch, but this does vary, again due to stem thickness and amount of branching
35-50cm long
 
Short bunches
Approx 20 stems per bunch
25cm long
 
The blues and purples are very similar and more on the purple spectrum than blue but when put together they are different enough to have as separate colours. Hopefully the differences show in the photos.
