I have just bought a yucca (stemless type) with curly leaves. I was reading that the yucca tends to produce pups that are really prolific. Also, once you get a yucca, it is really hard to get rid of it as it grows back from left over roots.
I would like it to remain in a limited space and would not like to do too much digging up and dividing.
Is this the right choice? I live in Toronto
Without knowing the exact variety of yucca you have purchased, it is difficult to say whether your plant is actually hardy enough to withstand a Toronto winter outside. Perhaps your best bet is to grow it in a pot, outdoors in a sunny spot during the warmer months and take it inside or at least into a garage or shed for the winter. This way, you can control its spread.
