Can you say garden? How about Trending?

I'm on a garden art quilt rampage, or I think I may be doing what is called "trending", but on a personal level. Honestly, I'm not entirely convinced,I have it right, there are so many new phrases that just go over my head.> For example, hash tags? What on earth are they? N0 clue, I likely stand out like a sore thumb, "What on earth is that woman talking about ?".
