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!

Deck Gardening 2024: Growing Alstroemeria

 

It’s important, when you have limited space and/or a limited number of containers in which to plant, that you plan your garden carefully. Pay attention to what you use the most when you’re in your kitchen, and grow those things. Don’t allow your head to be turned by something that will take up space and that you’re not going to use. That said, I always save one large plant pot for something experimental every year. I will say that most of the time my experiments fail.

 This year, because this is one of my favorite flowers, I decided to pick up the second to last Alstroemeria that I saw on a high shelf at the local garden center. It was nearly $30, so I hesitated a good bit before I finally put it in my cart. I have long been curious as to how these grow, if I can keep it growing, and of course, the big thing is if it returns the following year because it is a perennial. My interest was in doing pink and white flowers on the deck this year with a touch of purple. The only color of Alstroemeria they had was this peach and white with a yellow center. I will let you know how things progress. Fingers crossed it thrives, and I have beautiful cut flowers all summer long. 

What would you like to experimentally grow this year?

UPDATE: Isn’t the garlic progressing nicely?
