I either am at the cut off in climate for foxtails or mine(discount,had only a frond and a half) wasnt healthy enough to grow but one frond in 2006-then 2007 frosted all leaves,and to this day-right now,its a firm trunk,spear does not pull,no growth at all.Slowest death dance in the history of palms.A healthy thick growth of Canna's at its base is why I havent tossed it ..yet.

I never have tried Royals.

So,for you 9b,10a.. and for you in Melbourne-which does well?
