Many years ago when I first started dabbling in gardening for myself, I was always on the lookout for free plants and people were always willing to give away their extras once they knew I would take them. Talk about gullible!!! How did these plants make my list? Some are invasive or aggressive spreaders and some just take up a lot of space when there are more attractive perennials that could be living in your garden instead. Just a little disclaimer here.

Many years ago when I first started dabbling in gardening for myself, I was always on the lookout for free plants and people were always willing to give away their extras once they knew I would take them.
Talk about gullible!!! How did these plants make my list? Some are invasive or aggressive spreaders and some just take up a lot of space when there are more attractive perennials that could be living in your garden instead. Just a little disclaimer here. We have lots and lots of readers from gardening zones 3 through 10 here at Gingham Gardens. Pretty cool, right?
What is considered invasive, aggressive or a vigorous spreader here in my zone 4b garden is not necessarily so in your gardening zone. Be sure to read through the comments section at the end of the post where readers have listed their nuisance garden plants and plants they wish they had never added to their gardens.

Definitions for the terms invasive and aggressive are somewhat intertwined. DNR websites for states have their own definition of what invasive plants and aggressive plants mean. Native purists will get upset when I refer to some natives as being invasive or aggressive. Again, plants grow differently in different soils and climates.
Ugh, I came to hate this stuff. Ground cover indeed and it also covered everything in its path. Snow-on-the-Mountain is so invasive and it spreads by underground runners. I worked for probably 3 gardening seasons eradicating it from my shade garden. Do not let this beauty fool you. Ostrich Fern is another plant that spreads by underground runners and definitely one of those plants not to grow in your garden. But, proceed with caution!
Tansy tanacetum vulgare — is a perennial flowering herb that has a spicy kind of scent and is said to ward off mosquitoes.
Long ago it was used for medicinal purposes. It has a ferny type foliage that looks great all summer and the cutest little yellow button flowers. In addition to being invasive, the oils in tansy are highly toxic so be sure to wear gloves when handling it.
It spread into the grass and it encroached on neighboring plants. What a mess and another pain to get rid of. Honestly though, I look at the picture below and think what a pretty plant and it looks so good with the Shasta daisies, I want some. Fight that urge, you crazy woman! Ox-eye Daisies chrysanthemum leucanthemum - such a pretty little daisy that can easily be mistaken for shasta daisies chrysanthemum x superbum. Ox-eye daisies are weeds. They do not belong in a home garden flower bed, because they will take over.
Creeping Bellflower campanula rapunculoides — There are many, many varieties of campanula and lots of them are very well behaved. Creeping Bellflower is not one of them. It is like the thug of a flower garden. I inherited some Creeping Bellflower with our current home and I cannot get rid of it. I even went so far as to dig up the entire small area where it was growing and by the end of summer it was back. They have this evil long tap root that breaks off with a sneeze.
There are other varieties of campanula that are quite aggressive too, so just be careful and do your research before you purchase campanula. She told me it was naughty, but I had to have it anyway. I really had to work to keep it contained. See how well behaved it looks in the picture below.
Sorry, its an illusion! When we moved to our current home, there was tons of ribbon grass and I set out right away to get rid of every last blade of it. These perennials are not necessarily invasive, but they are definitely aggressive, and most gardeners would be better off not bothering with them. Lily-of-the-Valley Convallaria majalis — The flowers on Lily-of-the-Valley are so sweet and their fragrance is heady.
I love to pick bouquets of them and bring them in the house. They are naughty spreaders and do not stay where you put them despite efforts to contain them.
Common Orange Ditch Lilies hemerocallis vulva — I think these are my least favorite flower. They are prolific spreaders and they are the devil to get out of your gardens. These probably belong in the invasive section, because they crowd out other plants. Plus, ditch lilies take up so much space and there are so many other beautiful, cultivar and hybrid daylilies that you could use in place of ditch lilies. In my first garden makeover at our current home, I dug dozens of ditch lilies out of most all the flower beds that I made over.
They are fine along roadsides in ditches, just not in a residential setting. Crocosmia montbretia — Ugh, definitely not a favorite of mine. When we moved into our current home, there were Crocosmia plants everywhere! The blooms are interesting, but mostly just meh. Again, there are so many other perennials that are prettier and bloom longer.
I do have to say my sister grows the red Lucifer variety of Crocosmia in her Colorado Zone 5 garden and it is gorgeous. Anemone anemone sylvestris — Again there are many different varieties of Anemone, some of them well mannered, but this particular spring blooming Anemone Sylvestris, not so much. These pretty little white wind flowers spread like wildfire. I would not add this variety to my gardens again. Holy cow, I quickly fell out of love.
This was not the plant for my tidy flower garden. It spread by underground rhizomes and was anything but obedient. They are not supposed to be spreaders. I purchased one a few years ago and it has remained a nice, tidy clump.
And, they are definitely the most prolific hosta out there. Plus, slugs are so happy when you add royal standard hostas to your garden. That being said, once it starts flowering, it gets sort of ratty looking, and the flowers are not all that attractive. It just takes up too much real estate in the flower garden and has even spread to our lawn. Lambs Ear is a known bee magnet which is good, but there are tons of other prettier flowers that are bee magnets too. Blue Lobelia lobelia siphilitica — Not to be confused with the annual lobelia variety or the red perennial Cardinal Flower lobelia cardinalis.
Blue Lobelia is a native wildflower that is very pretty when it is blooming for maybe 2 weeks , but it spreads by seed like crazy. This is one flower that I think needs to stay in a wild prairie or meadow setting and not in home gardens.
Just my opinion. Most of the plants that made my list are also readily available at local gardening centers too. So how on earth is a novice gardener, or even a seasoned gardener like me, supposed to avoid ending up with perennials that will take over your garden. My best advice is just to read up and ask questions.
I happen to be one of the unlucky ones that lots of these naughty plants came with the house we purchased. I recommend doing your homework up front and planning what plants you want to purchase for your gardens. Also, be sure to read the comments section to see what other plants readers have listed as plants not to grow in your garden.
These plants include: bee balm, lamium, ajuga, cherry bell campanula and a few other varieties and agastache. Have you ever planted a perennial that you regret planting, or any on my list of plants not to grow in your garden?

No where did I find anyone complaining about perennial yellow cosmos. This fall I decided to take out a patch of them so that I can see the plants behind them. What a surprise for me—the roots are as if they are made of iron. I finally found that putting a shovel underneath them far enough I could lift them up and then cut through the roots with my hedge loppers, one root at a time.
Has anyone else run into this problem, or am I just getting too old and weak to be doing this kind of gardening? Would love to hear your comments! Hi Sharon — Thanks for stopping by Gingham Gardens. Are you sure the plant in your garden is what you think it is?
As part of the "Sonic Succulents" exhibit at the Brooklyn Botanic Garden, visitors are encouraged to touch plants and listen to what that contact sounds like. There's an old belief among farmers that on a quiet night, if you listen closely, you can hear the sound of corn growing. A new exhibit at the Brooklyn Botanic Garden proves that theory to be true. Take a listen:. Adar is a sound artist based in Los Angeles. She's passionate about the natural world and says her goal is to show people that plants aren't that different from us: They grow, breathe and even communicate in their own ways. And so, back in May, she planted a patch of corn within the Brooklyn Botanic Garden and has surrounded it with large yellow megaphones that visitors can stick their heads inside to listen to what a growing stalk sounds like.
These fumes are the key to answering the question on how plants can communicate with each other. Two studies were conducted in where.
Make a donation. Watering is key to growing plants well, so here we look at how to get it just right. This not only means providing the water our gardens need, but using it wisely. Water is a precious resource and supplies in the UK are under pressure from the effects of climate change, population increase and the need to protect the environment, such as river levels for wildlife. Water in the mornings, if you can, as this is when the sun comes up and plants will start to use water. The foliage and soil surface is also likely to stay drier for longer than evening watering, discouraging slugs, snails and mildew diseases. Plants start to transpire in sunlight, drawing water from the soil, through their roots, up their stems and out through tiny pores on their leaves called stomata. Evening watering is also fine, as the cooler conditions mean less water is lost to evaporation. Watering in the heat of the day is not a good idea as much water is lost through evaporation from the surface of the soil and the plants will use water more efficiently if watered in the cooler parts of the day.
Bloomin' Flowers is something of a shopping secret in Albany. We are not on the main street and we're generally pretty modest, but we just keep delivering and building our loyal following. We thought long and hard about what our customers want: prompt, friendly service, creative flair,and value for money. We take great care over how bouquets are presented, and because we grow many of the blooms ourselves our customers can be assured that the flowers are fresher and will last longer when they get home.

Did you know houseplants can communicate? Thankfully, plants communicate with us all the time. No one likes stress, not even plants. Stressors can include lack of water, over watering, temperature change, less light — you name it. The plant will likely adapt to its new situation.
Plants can be exposed to many stress factors such as disease, temperature changes, herbivory, injury and more. Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes ,  other plants  of the same or other species , animals,  insects,  and fungi. As such, whether neighboring plants have evolved the capability to "eavesdrop" or whether there is an unknown tradeoff occurring is subject to much scientific debate. In Runyon et al. Dodder seedlings show direct growth toward tomato plants Lycopersicon esculentum and, specifically, tomato plant volatile organic compounds. This was tested by growing a dodder weed seedling in a contained environment, connected to two different chambers.
Each year, we grow some of the Garden's plant giveaways in the Regenstein Fruit & Vegetable Garden's raised beds, and a few brave staff do the same at home.

First, in doing some research for this blog, I found writing this blog more educational for me than I originally thought it would be. Over the years I have talked to many customers who wanted to know what was this grey looking barnacles growing on their dogwood trees or on their azalea plants.
Make Your Own List. Internationally known ecologist says plants are grievously overlooked, because no life on earth would exist without them - essential reading on plants. This is a book by somebody who studies plant fossils and their role in life on earth. Their relationship with the zoocentric world is like that of a perplexed parent of a sullen teenager who refuses to acknowledge that his very existence depends upon them. Beerling believes that too many people think that plants are a pretty dull chapter in the history of life and one that can be skipped.
