yeah, I did wonder, we've had -9° but it would die in the pot anyway... I've got oleander, yuccas, an olive , cordyline, all outside and they've been OK if a little battered
it was in a pot and congested, I try not to repot as last year had 63 🪴🪴 in the garden, it survived over winter so I thought sod it and shoved it in the ground
I've got a couple of varieties but they never get big, they're in a border where nothing thrives tbh, I've got a massive walnut 🌳 which stifles a lot of plants
