'Tender' is really a relative term, isn't it? Some of the cacti I grow are tender for my winter temps, but not further south. Same with the aloes. All three of those I grow survive winters outdoors in Austin, but not for me prox. 200 miles north. Since the forum covers ALL cacti and succulents regardless of what may cause them to be tender and require special steps to grow, I'd think the word was superfluous in the title. Just about anything originating from South Africa is going to be tender here and a lot of things that come with 'Alpine' as part of the description is going to be difficult - the first due to winter low temps and the second due to excessive dry summer heat.
Just my opinion. It's not important to me one way or the other.
