Know what’s a super-frugal plant?

The hyacinth bean.

I love these things.

My brother started growing them years ago when he was the landscaper at church. They now cascade over a long fence there and produce hundreds of bean pods every year, each filled with little purple seeds.

This seed production is what makes these such a frugal plant…a single seed can grow a plant that produce more than 50 seeds. Each of those little purple blooms in the first photo will produce a bean pod, so you can imagine the copious output of seeds.

Unlike the seeds of some plants, the hyacinth’s seeds are very easy to save (just pluck the pods once they’ve dried on the vines) and very easy to plant (the seeds are the size of dried kidney beans and germinate as easily as most beans.).

This makes me very happy because I like to have beautiful plants at my house, but I don’t like to spend lots of money on plants that only give me beauty for a single season.

When we moved to this house, I snagged a couple of the pods from the church fence and brought them home. I planted them along a north section of fence the first year and they didn’t do very well. These plants love light and there’s just not enough on the north side of a house.

I’ve done some experimenting around, and I’ve discovered that they do really well around my mailbox.

They’re also pretty happy on the fence which intersects with the south side of our house.

I’ve grown them on the mailbox and on the south fence before, but this year I tried planting them in two new places. In the spring, when Sonia and I walked around the yard with our container of seeds, we looked for planting spots that provided sun and a place to climb.

So, we put a single plant by the swingset, and though it needed a little help to begin climbing up the side, once I tied it up a bit, it took off and looks beautiful even though it hasn’t really bloomed yet.

I also put a couple of these plants in a pot on my deck, thinking that the deck railings would provide a place for the vines to climb. I had to move the pots a few times because we pressure washed and stained the deck this summer, but once I let them be, they did indeed climb up the railings.

I love that they’re visible from both sides, and because they hang down, they’re even visible from under the deck. These deck plants are just about to bloom, but even without the blooms, I think the green vines are beautiful to look at.

You can buy hyacinth bean seeds on Amazon and at other online stores for less than $5. Because these plants produce such a prolific number of easily harvestable seeds, your first package of seeds is the last you’ll ever need to buy. In fact, after your first season you should have more seeds than you know what to do with, in which case you can give some away to your friends and neighbors.

Or if you’re very fortunate, maybe you already know someone who grows these, and you can be the recipient of their leftover seeds.

Either way, if you’ve got sunshine and a place for plants to climb, I highly recommend giving this plant a try.

Do you grow any plants like this? If there are other easy-to-grow plants that produce easily saveable seeds, I’d love to hear about them!

Thank you for the information. I love learning about different kinds of plants and this is helpful. Keep sharing more like this.

Chives! I love growing garlic chives - chopped and mixed into some sour cream with a little vinegar, they make a tasty salad dressing. And the plants are so easy to divide year over year. And spinach - spinach isn't as pretty, but lordy, does it produce a lot of seeds when it goes to seed!.

I really should give spinach another try. I usually forget about it until it's too late in the spring to plant it; I know it doesn't do well in the heat at all.

Thanks for the information! My neighbors took a cutting from such a vine, popped it into the ground, and it grew beautifully. They didn't know what it was, though. I'll be sure to tell 'em now!

I'm not surprised it's such an easy plant to grow.

4 o'clocks! I had 3 plants around my front steps last year and I gathered over a 1,000 seeds. The make a pretty hefty black seed, easy to see cupped among little green leaves. And they smell heavenly, butterflies and hummingbirds love them, and they reseed themselves so they come back every year. Blossoms are yellow, white and hot pink, on mine at least. One plant grows to about 2' x 4' where I live and we are in the middle of the worst drought ever. I can't imagine what they would look like if they actually got rain water. Love your posts

I could give you a list a mile long of easy-to-grow, frugal plants. Cosmos, Marigolds, Black-eyed Susans, Daisy, Zinnia, Chives (Well, they are pretty when they flower and yummy in the kitchen, too!), Hardy Hibiscus, Sweet Williams and name a few. ;-)
