I have heard it take 3 to make a collection.
I have had this variety of Hen and Chicks for years. It started out as one someone gave to my brother. Then I got a start of it when we moved here. It is growing in lots of places around the yard, but I like it in this pot.
Recently, I got this one. It seems subtly different than the previous one. It had arrived in this pot with a clearly different variety. I purchased it at Rural King a couple of weeks ago. Don't worry, it was on clearance.
Then a friend at work gave me this variety several years ago. I love the spider web appearance.
And look, it is blooming. This might be the first time I have seen a Hen and Chick bloom. Pretty cool. So, I am counting 4 different varieties, definitely a collection.
