After having grown and shown Dahlias at national level for many years I formed Tulchan Dahlias. 
Why Tulchan, it is an unusual name. 
Besides having this addiction to Growing Dahlias. I have been an avid Fly fisherman for as long. Tulchan is a Sporting estate on the River Spey in Scotland. 
I was fortunate to catch my First Salmon, fly fishing many years ago on Tulchan D beat. 
The first Salmon is one that you never forget.
The pool name was the Stream of Craggenmore, a streamy piece of water pouring into a round holding pool. Its located directly below Craggenmore Distillery one of the famous Speyside Malts.
It was an overcast but dry day, 12th July 1983. A Tuesday Morning, time was 9:50 am. The fly was a Silver Stoats Tail on a size 12 Esmond Durry chromed hook. All alone I was trembling as I stood in the edge of the stream for fear of losing the fish. I had lost others at the net. 5 minutes later I beached a slightly red male Salmon of 8lbs. To celebrate I just had to get myself a wee dram to steady myself and record the accomplishment in the Fishing log.
As I had mentioned something one doesn’t forget. 
So that is why I chose Tulchan to prefix the Dahlias that I have hybridised and RHS registered. There will hopefully be more in coming years.
Maybe they will be something you do not forget.
