Welcome. When we talk about a measurement, we mean how tall the bloom stalk is (from base to top of bloom). Width of flower is not usually a big factor.
When did you buy the house? How many of the "Before the Storm" do you have? This is how you can start a way of narrowing the field for the correct name.
As an example: The last mentioned possible ID was "Coal Seams". Let's look at "Coal Seams" vs "Before The Storm".
