Growing Alstroemeria in Pots, Indoors and Out

 

Back in June 2024, I published a post about growing alstroemeria (that you can read here) and admitted I was nervous about dropping $30 on a plant that might not survive the summer. Fast-forward to today, and I’m laughing at my old self. Not only did that single plant sail through the heat, but in the summer of 2025 I couldn’t resist buying it a companion. Now? I’m 100% all-in.

 

They looked stunning all summer in the garden—lush foliage, nonstop blooms, and zero drama. But what truly blew me away happened when the cold weather hit. I brought both pots indoors, crossed my fingers, and hoped they’d at least stay alive. Instead, they exploded with growth and kept flowering nonstop all winter long. Every single day I had a fresh bouquet on my desk. Fresh-cut alstroemeria in January? Yes, please.If you’ve ever walked past these beauties at the garden center and hesitated because they looked “too fancy” or “too expensive,” stop right there. They are worth every penny.

Here’s the secret to success: In zones where winter temps never drop below 40°F, you can plant them straight in the ground. Everywhere else (like most of us), grow them in pots. Their rhizomes hate being disturbed, so digging them up every fall isn’t ideal. Just wheel the pots inside when frost threatens and watch the magic happen.

 

My new motto? Alstroemeria isn’t just a summer flower—it’s a year-round joy. If you love fresh flowers but hate the grocery-store prices, do yourself a favor and give these incredible plants a try. You’ll thank me when you’re cutting blooms in February!
