Tuber growers/sellers, what do ypu think the staying power of dahlia popularity is?

Pretty much the title. I am relatively new to growing and selling (6th year growing, 3rd year selling) so I am not certain how long this has been popular for. But, even though I play the game, I sometimes think wow 50 bucks for one tuber is wild!! Then pay it anyway lol. (I know certain varieties are much more than that!)

I'm mostly asking because in my 5 year plan, we are planning to buy a home with a bigger yard, so I am wondering if factoring larger scale tuber farming into that plan would be prudent and wise. (Also, no i am not doing this solely for the money, but one doesnt need space for 100+ plants for their own use, no matter how stunningly beautiful the flowers are! Lol)

Thanks for any and all thoughts!
