Are Canna Lilly perenial? Best way to care for them. Best from seed or rhizome?

    Do you mean Canna’s or Calla’s (Zantedeschia).  Both are perennial but are generally not hardy in the UK, and need protection from frost.  I keep ours in pots in our unheated greenhouse over Winter.

    Cannas are perennial, but half-hardy, which means they only survive temperatures above freezing. It is not practical to collect seed as it is very slow to grow and genetically unstable. What I do is;  every year when frost is forecast, lift a good plant and cut off the new side growth,then  pot itup and keep it in a warm, sunny place over winter. As soon as it warms up again ( April or May, depending which part of the country you are in) you can  plant it out. Remember Cannas are very greedy and need lots of warmth, water, sun and fertilizer. Good luck!

    Have to disagree about Canna seeds. They are very easy to grow and there are several varieties available which come true.
