In Defense of Frivolous Flowers
I'll be honest with you. I spend a lot of time talking about natives. About long-term thinking. About not impulse buying at the nursery. About plants that belong here and will still look good in August.
And then March arrives, and I completely lose my mind over zinnias.
I contain multitudes.
Here's the thing about spring annuals: they're not a long-term investment. They're not sustainable in the strictest sense. They'll be done by fall and you'll start over next year. By my own logic, I should probably be steering you toward something more practical.
But there are bees all over my fruit trees right now. My lettuce has bolted into something almost architectural. My baby zinnia seedlings are sitting in their little cells in the greenhouse, ready to go out, and I am genuinely excited about it in a way that no amount of native plant evangelism can fully explain.
Spring annuals are a bouquet you plant yourself. And that is enough of a reason.
What to Plant Now for Pure, Unapologetic Color
These are the ones I grow, love, and will defend:
Zinnias
Zinnias are the workhorse of the spring cutting garden. They bloom prolifically, they love Houston's heat, they come in every color imaginable, and they attract every pollinator in the zip code. Plant them, cut them constantly, and they'll reward you with more. They're also one of the easiest flowers to grow from seed if you're inclined that way.
Cosmos
Cosmos are the opposite of zinnias in the best way — airy, delicate, swaying in every breeze, making everything around them look romantic. They're equally easy and equally generous.
Marigolds are the dependable friend who never cancels. They bloom all season, they deter pests, they come in every shade of gold and rust you could want. Underrated. Always.
Gomphrena is the one people overlook at the nursery and then fall in love with by July. Globe-shaped, long-lasting as a cut flower, and genuinely unbothered by Houston heat in a way that earns real respect.
Sunflowers are an event. You don't just grow sunflowers — you grow a moment. Plant them in the ground (not raised beds — they're allelopathic and will sulk their neighbors), stand back, and wait. Worth every minute.
The "Just Make It Beautiful" Path
For most people, the right move is to buy transplants. Walk into the nursery, pick the colors that make you happy, bring them home, and plant them. That's it. Annuals are supposed to be all joy, no stress — and transplants get you there faster with a lot less fiddling.
The nurseries are fully stocked right now and everything is gorgeous. This is exactly what they're there for.
The "I Want the Wine-Red Zinnia Nobody Else Has" Path
And then there are those of you who, like me, are already elbow-deep in seed catalogs in January. Who want the four-foot tall variety that isn't available as a transplant anywhere. Who find the whole seed-to-bloom process genuinely thrilling rather than tedious.
If that's you — welcome. You're my people.
Start seeds indoors now if you haven't already. Check out Botanical Interests, Baker Creek Heirloom Seeds, and Johnny's for variety selections that will make your head spin in the best way. Experiment. Grow five different zinnias and see what surprises you. That's half the fun.
Don't Forget Your Veggie Beds
One of my favorite things to encourage is co-planting a few annuals directly into your raised vegetable beds. It sounds frivolous but it's actually practical — the right companions attract pollinators, deter pests, and make a purely utilitarian space genuinely beautiful.
A few that do this job beautifully:
Small zinnias and marigolds — classic companions, easy, effective, cheerful
Nasturtiums — edible flowers, pest deterrents, and they sprawl in the most charming way along bed edges
Angelonia — underused, long-blooming, and perfectly at home in Houston heat
Tuck a few of these into the corners and edges of your veggie beds and you'll have something that's both productive and genuinely lovely to look at all season.
There's a version of gardening that's all strategy and long-term thinking and making the responsible choice. I believe in that version. I practice that version.
But I also have zinnias going into the ground this weekend, and I have absolutely no regrets about it.
Go get your flowers.
