What is a grower bunch?

A grower's choice on quantity per bunch

A grower bunch is a grower's choice on quantity per bunch depending on the flower type.

For example, some growers sell Lisanthus in 7 stem bunches, yet other growers sell them them in 5 stem bunches.

The price is reflected in these differences. Hence, the 7 stem bunch would be more expensive than the 5 stem bunch.
