Grow Something Bold and Beautiful with Our Nasturtium Seeds

There's something about nasturtiums that just makes a garden feel alive. Maybe it's the way those bright, trumpet-shaped flowers spill over the edges of a pot, or how the leaves look like tiny little lily pads scattered through your raised bed. Whatever it is, once you've grown nasturtiums from seed, you kinda never stop.

At SeedOrganica, our nasturtium seeds are picked for home gardeners — folks who want color, flavor, and a plant that doesn't demand a PhD in botany. These aren't fussy plants. They're honestly one of the most forgiving things you can grow, whether you've got a sprawling backyard plot or just a couple containers on a sunny balcony. And here's the thing most people don't realize at first: every part of this plant is edible. The flowers, the leaves, even the seed pods. They've got this peppery, watercress-like kick that'll seriously level up your salads and summer dishes. Fresh stock, quality tested, and ready for your dirt.

Explore Our Nasturtium Seed Varieties

We carry a handful of nasturtium varieties, and each one brings something a little different to the table — literally. If you're looking for that classic trailing habit that cascades beautifully over hanging baskets and window boxes, our trailing nasturtium mix is a great pick. It throws out blooms in shades of red, orange, gold, and creamy yellow all summer long. Real showstopper stuff.

For folks who prefer a more compact, bushy plant — maybe you're working with smaller containers or want neat little borders — the dwarf varieties keep things tidy without skimping on flowers. They're perfect for kitchen gardens where space is tight but you still want that pop of color right next to your herbs and greens.

Then there are the heirloom varieties. If you're into that old-school gardening vibe, these are the ones your great-grandmother might've grown along a fence line. Deep, saturated colors. Slightly different leaf shapes. A little more character, y'know? And flavor-wise, some of the darker-flowered varieties tend to pack a bit more of that signature peppery punch — super fun for garnishing dishes or tossing into a mixed green salad when you want to impress people at a cookout without really trying.

The diversity here means you can mix and match depending on your setup. A trailing type in a big pot near the porch, some dwarf nasturtiums tucked between your tomato plants (they're actually great companion plants, by the way — more on that in a sec), and maybe an heirloom variety in a dedicated cutting garden for edible flowers. It all works.

Gardening Insights: How to Grow Nasturtiums Like a Pro

Okay so here's the deal with nasturtiums — they actually prefer to be a little neglected. Seriously. Rich, heavily fertilized soil? They'll give you tons of gorgeous leaves and barely any flowers. They're that one plant where "poor soil" is actually the sweet spot. Sandy, well-draining, not too nutrient-heavy. If your garden soil is on the lean side, nasturtiums will thank you with blooms for days.

Sunlight-wise, aim for full sun — at least 6 hours of direct light. They can tolerate some partial shade, especially in hotter climates where afternoon sun gets brutal, but you'll get fewer flowers. In most of the continental US, you can direct sow seeds outdoors after your last frost date. The seeds are big and easy to handle (no squinting at tiny specks, thank goodness), and they sprout pretty quick. Just poke 'em about half an inch to an inch into the soil, water gently, and wait. Most gardeners see sprouts within 7 to 14 days depending on soil temperature.

One little tip that a lot of seasoned growers swear by: soak your nasturtium seeds overnight before planting. That thick seed coat softens up and it can help speed things along. Not required, but it's a nice trick to have in your back pocket.

Watering? Keep it moderate. They don't like soggy feet. Let the soil dry out a bit between waterings. Overwatering is probably the number one mistake people make. And as far as pests go, nasturtiums are famously used as a trap crop — aphids love them, which means the aphids go to the nasturtiums instead of your vegetables. Some gardeners plant them specifically for this purpose. Kinda clever, right?

One more thing worth mentioning: nasturtiums are annuals in most zones. They'll go strong from late spring through the first frost. In warmer zones (9–11), you might get them to overwinter or reseed on their own. But for most of us, they're a plant-and-enjoy-this-season kind of deal, and honestly that's part of the fun. Fresh seeds, fresh start every year.
