Thanks for the tips, Greg! (I just did a double-take - your surname is one letter different from a Greg I know offline.)
One question, when you say "As soon as you see roots you can plant it, and water as usual.", I'm not sure what you mean... if the cutting is laying on top of the soil, its new roots will grow down into the soil... so what do I need to plant? Do you pile soil up to cover the roots, or something more? Sorry if this is a silly question... I'm a novice at growing things I can't eat
The one at my work has been blooming nonstop since I started in November... I won't be surprised if it is a year-round bloomer, though I know any plant I start off of it will take a while to get to that state.
I've always thought hens and chicks are adorable, but don't have any in my garden. I'm slowly expanding my collection of succulent, easy-to-propagate houseplants - I have Aloe, Kalanchoe, Hoya and hopefully soon a Christmas cactus... maybe some Sempervivums will find their way in one day
