Homebrewing herbal tea

Thanks for your suggestions on alternatives to tea bags for cold brewing tea.

At the moment, I plan to buy a package of the biodegradable tea bags from Vitamin Shoppe and phase out my pre-bagged tea in favor of loose leaf tea. (I’ll use up the rest of my pre-bagged tea, but I won’t replenish it when it’s gone.) I will revisit the infusers and filters you suggested at a later time.

What kinds of loose leaf teas do you brew, and where do you buy them? While black tea leaves, green tea leaves, whole ginger root, and whole cinnamon sticks are easy to find in local stores, I’d like to use other ingredients as well, especially hibiscus.

Hibiscus:
Lots of offerings at Amazon.

(Many tea bags, but also loose ‘bulk’ too.
