Few of them tolerate much frost, and many tolerate no frost. They are warm-growing, full-sun plants, except in hellish climates, like where I live. They also struggle severely with hot night-time temperatures. If you live in a rainy climate, grow them in pure pumice, or something equally fast-draining. The high alpine ones are even harder to grow in warm climates, so stick with the lower-elevation ones. Puya laxa is a very attractive plant with narrow, white-flocked leaves. I think it could be managed easily in a 1-gallon / 3.78 liter pot. Leo Martin Zone 9? Phoenix Arizona USA
