10 Self-Seeding Plants to Save You Time & Money
Self-seeding plants are perfect for gardeners short on time.
As the name suggests, self-seeding plants are plants that naturally scatter seeds across your garden.
These new seeds then germinate and steadily grow until they flower, and then this new plant scatters its own seeds and the cycle begins again. This continuous cycle will repeat, more or less, forever.
This means that by carefully choosing self-seeding plants for your own garden, you can allow it to gradually evolve and change over time, all with no effort on your own part. You can just let nature take its natural course.
Once you have invested in that first packet of seeds, you can quickly fill your garden at an extremely low cost. Once the first seeds have been sown, you can put your feet up and let your garden take care of itself.
Fortunately, there is a huge variety of self-seeding plants that are readily available, too.
Today, we are looking at some of our favourite self-seeding plants that will save you both time and money. It’s a win-win situation.
So, let’s take a look at the first self-seeding plant on our list.
Forget-Me-Not (Myosotis Sylvatica)
Forget-me-nots are one of our favourites on the list. They produce beautiful blue flowers during spring and summer that will transform any plant bed.
They can survive in most soil types and enjoy a partially shady environment, growing up to half a metre in height.
Also, if you find that you have too many growing and your garden is starting to look a little crowded, you can easily pull them out.
Poppy (Papaver Rhoeas)
Another popular self-seeding plant is the common poppy.
They form bright red flowers during the summer and will grow up to 75cm in height.
They grow well in fertile soil and their seed-filled heads will allow seeds to be blown around the garden. Before you know it, given the right conditions, you’ll have all the poppies you could ever need.
Foxglove (Digitalis Purpurea)
Next on the list is the humble foxglove. No summer garden would be complete without a foxglove, so we had to include them on our list of our favourite self-seeders.
Foxgloves are well known for attracting bees, which will help to pollenate the plants in your garden.
A word of warning, though; they can be toxic both to humans and to pets, such as dogs and cats, so are probably best avoided in a family garden.
Otherwise, they make for a fantastic summer bedding plant.
Mexican Daisy (Erigeron Karvinskianus)
Mexican daisies make the perfect addition to any garden.
As the name suggests, they are native to Mexico, but have managed to survive in Mediterranean areas and dry gardens in the UK.
Due to being Mexican natives, they love sunny areas of the garden and like to sit in well-draining soil.
They also have a tendency to grow in wall crevices, within rock gardens and in stone steps. Once established, these self-seeding plants will begin to multiply.
Sunflower (Helianthus Annuus)
Whether you’re a gardener or not, sunflowers – with their large, bright yellow flower heads – are instantly recognisable.
They can grow extremely quickly with the right conditions and have been known to reach up to 4m in height.
The flower heads produce a very large number of seeds, which will naturally scatter around the garden or can be stored for planting the following season.
Some gardeners may see marigolds as weeds but, given their beautiful orange flowers, we had to include them on our list.
They can spread quite rapidly, so if you don’t want to overdo it, you might find it’s necessary to keep them in check by removing excess plants from time to time.
Another reason to plant marigolds is that their smell can actually help to repel pests, such as blackfly and greenfly. Marigolds also attract hover flies, which feed on blackfly, so these beautiful plants offer a double whammy, as they have the ability to help keep pests at bay whilst looking pretty in the process.
Parsley (Petroselinum Crispum)
Although not technically a plant, parsley is a self-seeding herb that can provide excellent foliage around the garden.
Of course, this particular herb is an excellent choice for the grow your own enthusiast, as parsley can be used in a wide variety of recipes and as an attractive garnish.
Borage (Borago Officinalis)
Next on our list of self-seeding plants is borage, used by the ancient Greeks and Romans for its medicinal benefits.
The blue flowers of borage are particularly attractive to bees, making it a fantastic pollinator for a small garden.
The young leaves of the borage plant are also edible and can be used in salads.
If you have a dog, then borage may be best avoided as they can be toxic to dogs.
Rose Campion (Lychnis Coronaria)
Rose campion is a species of flowering plant from the carnation family.
It is native to Asia and Europe and produces vivid rose-purple flowers in late summer.
They form in clumps with grey foliage and can grow up to a metre in height.
Rose campion enjoys full sun or slight shade and, in order to prolong the flowering, it is recommended that you deadhead them.
Montbretia (Crocosmia ‘Lucifer’)
Montbretia, specifically in this case Crocosmia ‘Lucifer’, are deciduous perennials with long spikey leaves that produce beautiful red flowers in the summer months.
This self-seeder forms in clumps, with stems growing to 1.5m in height, and has the ability to quickly spread throughout the garden.
Crocosmia can also be propagated by division just before growth starts in the springtime.
They make a fantastic additional to any flower border and are ideal for cottage and informal gardens.
Self-seeding plants are not just good for gardeners who lack the time or ability to grow their own plants and shrubs, but would make the perfect addition to any garden.
It’s also an extremely cost-effective way to plant out your garden. Once you have that first pack of seeds, the plants will pretty much look after themselves from there on in.
There are many more self-seeding pants that we haven’t included on our list. We would highly recommend visiting your local garden centre to explore what they have available in the way of self-seeding plants, then get planting today.
