What Flower Seeds Can I Plant Now? Your Monthly Guide

The easiest and least expensive way to get lots of flowers all season with little work is to plant flower seeds directly in the ground. It’s incredible just how much you get from a tiny $3 pouch of seeds. And I believe it’s a great way for first-time gardeners or experienced gardeners who want to fill in a space. Direct sowing just means that you don’t start the seeds indoors weeks before putting them in the garden. Instead, you follow the directions on the package and spread the seed in the garden, usually after there is no chance of frost. Direct sowing is the easiest way to garden. All you have to do is choose where to plant them and water them while they sprout.

Today, I’m having trouble (is it really a problem?) because every time I think I’m done with seed orders, I see a blog post or an Instagram picture and have to get back to work. But really, I think I’m done. I was thinking about the seeds I plant and how thankful I am that they grow into little workhorses. From what I’ve seen, all of these plants bloom nonstop until the first frost. They add color all season, and many of them are loved by all kinds of pollinators.

So I thought I’d share my favorites with you. They’re all sun loving flower factories, and with the exception of a few, when they’re gone they’re gone. The first frost is usually the death blow. This is by no means a complete list of all the seeds you can direct sow. These are just the ones I’ve grown in my garden and love.

With so many options to choose from, there’s a sunflower for every situation. Some are garden behemoths perfect for the back of the border while others are small enough for containers. Every year I plant a different kind of flower in the middle of my vegetable garden. There are always a lot of bees, especially bumblebees, going through the flower centers. When summer is over and the flowers are no longer at their best, I like to cut them off their stems and put them between the fence posts so that finches can eat the seed.

(See picture at top of post.) It sounds a lot like a disease, doesn’t it? A Master Gardener teacher at the University of Illinois gave me some of these seeds many years ago, and I’ve never had to plant them again. Once you got ’em, you got ’em. But in a totally good way. It’s not like creeping jenny. Seedlings are easy to remove if you don’t like where the wind has blown them. I let them be most of the time, and I love seeing how well they get along with their friends. Little purple flower clusters float above the rest of the garden on thin but surprisingly strong stems that sway in the wind. The plant is see-through. The pollinators can’t get enough of them in my hot, full-sun garden.

This beautiful flower, which is also known as flowering tobacco, should be planted near a patio or window so that you can really enjoy it. The sweet smell is intoxicating and becomes stronger as the sun goes down. This is another I haven’t had to sow since planting it several years ago. The first year it was in my garden, I picked seed from the flowers. But I soon learned that it self-sowed and was easy to pull out of places I didn’t want it.

This plant from Renee’s Garden grows to about three feet tall and can get a little wild. I like that about it; it gives my garden a wild look that I really like.

If you’re an avid gardener like me you’re probably itching to get growing and fill your garden with beautiful blooms. But with so many flower varieties to choose from it can be tricky to know what seeds to plant each month to maximize your yields.

That’s why I’ve put together this handy guide on what flower seeds you can sow right now and what’s best to plant in the coming months. Consider it your monthly checklist of flowers tailored to your USDA planting zone.

The new year will be here before you know it bringing more chances to sow flower seeds. Whether you love roses, sunflowers, or pansies, follow this guide to discover what you can plant now and in the months ahead. Here’s to a colorful year of blooms!

Hyacinth Bean Vine (Lablab purpureus)

I’ve grown this fast growing vine in containers where the seed germinates faster than you can blink. I liked how it spread out over the pergola posts, but I haven’t needed it on the patio since the wisteria took over. It’s huge and can grow up to 20 feet tall! I saved seeds from the original vines, though, and they’ve done a great job of hiding unsightly parts of my garden. When I planted them in the ground for the first time last summer, they did even better. They quickly spread out over trellises, making a beautiful wall that no one could get through.

Heart-shaped burgundy leaves full of purple veining and sweet-pea like flowers on almost-black stems are eye-catching. Purple pods develop toward the end of the season that are striking in floral arrangements.

How can you look at this happy yellow flower and not smile? It’s my favorite black-eyed Susan. I bought the plants every year at the garden center and was upset that they didn’t grow again very often. I can direct sow them every year if I want them in the garden because they only come back every two years here. And I definitely do! They get about 2. 5′ tall. The dark side of these bright lovelies is that I rarely see pollinators on them.

My garden wouldn’t be my garden without a zinnia, or two, or three. I mean, I LOVE ZINNIAS! The fact that they come in many colors, flower shapes, and heights makes me love them even more. They never disappoint and flower non-stop all summer long. I love picking bouquets of them for the kitchen table. And the picking encourages more flowering so it’s a win-win.

I’m really excited about the Magellan series I discovered while touring Ball Seed Company’s trial garden in West Chicago last summer. At just 12″ tall and sporting 4″ to 5″ color-saturated flowers, Magellans are perfect for edging pathways or adding an upright pop of color to container gardens. I bought a few packets from Park Seed and, at the moment, can’t remember which varieties. It’s late.

As the name suggests, this heirloom vine’s flowers open from cone-shaped buds at night to release their sweet scent. Last summer, my plants had flowers that were 5 to 6 inches across and really shone in their pot on the patio, where a trellis let them climb up the wall and onto the pergola.

Because this and the flowering tobacco bloom in the evening, I think that’s why there are more pollinators in my garden at night. A Polyphemus moth the size of a large man’s hand surprised me in the compost bin last summer.

I used to hate them, until Big Duck walked into my life and made me reconsidered their merits. Not the prettiest smelling flower, I found the colors of the marigolds of my childhood downright ugly. The only thing I liked about them back then was how easily their “heads” came off. My grandmother had them in her garden.

Last summer, All-America Selections sent me Big Duck Gold to try out. You can read about it here. This guy developed huge pompom flowers above lush blue-green foliage. There are some marigolds that I like, but not all of them. I plant mine along the edge of my vegetable garden because that’s where they do best. Some people say they keep rabbits away, but I don’t know for sure. I didn’t have many rabbit problems last year. Perhaps this is why.

Mexican Sunflower (Tithonia rotundifolia)

This is by no means the prettiest plant, it’s actually quite ugly and sprawling. I forgave these shortcomings rather quickly when I realized just how nuts the monarch butterflies were for it. The flower seeds shot up fast and quickly overcame the center of the vegetable garden. It seemed like a good idea at the time but live and learn. At least the butterflies appreciated it. I’ll plant this again in a different part of the garden so it has more freedom, but I can still watch the pollinators from the patio or the window.
