For several years, I have looked in the catalogs at Violas. I have little violets in my grass and in a couple of my gardens I have to diligently eradicate, or they would take over. Can anyone tell me if the following violets are aggressive? If you have grown any of these, I would like your comments. Here's the ones I am considering and are listed in Bluestone Perennials:
Viola cornuta 'Blue Perfection', Viola c. 'Chantreland', and Viola c. 'Lutea Splendens'
Viola Rebecca (Bluestone says it doesn't spread)
Also, these are so cute, I wonder if one could grow them indoors as house plants?
I know wild ones grow as house plants ,not sure about the cultivars offered more recently. I hear some of the violas get larger now. If they are Pansy type viola I would imagine a cool place for them and they still would.
Depending on where you are the garden type ,earth, sun, shade, any plant may be aggressive , you just have to try and find out , gardeners intuition ,is every ,and all when it comes to choosing plants. lol that is the trick to all ,isn't it?
Birder, I've tried viola Etain a few times, because the pictures in the catalogues look fabulous.
But I've never gotten it to grow.
I've blamed our heat & humidity, but that's my favorite excuse for any plant demise.
I haven't tried the others.
I've got a pretty little white viola with nice cut foliage (which arrived as a stowaway in a different plant order) has returned for several years now. It does reseed around, but I don't find it annoying at all - it's so pretty that I welcome it scattering itself around. Here's a picture of it. I think it might be viola pedata, but I'm not sure.
I've inherited several types of violets, including yellow, and I love them all. I must admit, though, that the white ones could be a nuisance. There's one place, right at the base of a Santolina, that comes up vigorously every spring and all summer long, no matter how many times I pull it up -or how deep I dig. The white clump in Pic4 I leave alone as it is next to ferns, and I figure it's a fair battle between them for the territory.
I don't have any info on the named varieties, but have to think they are less rampant? Others here may know better...
Your white violets look like a white version of the invasive purple ones running rampant in my woods.
I think you're right to be wary of it.
I've given up on trying to remove the purple ones.
They are everywhere; manual removal just isn't realistic.
I've heard soil amendment is the better way to control them,
since you have to change the soil condition so it's not so conducive for their growth.
But frankly I'm not sure what amendments they're talking about, so I'm not much help!!.
Most likely you have to change the PH, and add lime since they thrive in acid soil. The east coast is all acid, and our native plants, as well as many favorite garden annuals and perennials, are happy in it. I add compost and manure from time to time, which tempers the acidity somewhat, improves texture and provides nutrients, but the violets keep on coming. Maybe for lawn it would be ok to really work on the ph, but in my garden I think too many other plants would be affected. I'd rather just keep pulling the violets out where I don't want them. I'm happy enough to see them when there's so little else.
Have to agree, Pfg. I've "rescued" the wild ones out of lawn and moved them to garden beds where they thrive and get nicer flowers. Always look forward to them in the spring. I think DH has used Weed B Gone on some in the lawn in the past but it takes a couple of applications.
Well, I was wondering if the violets that are sold in the catalogs are as prolific as the little wild ones in the lawns. Guess I will do some research.
And, are the ones that are a combo of purple and yellow that grow in the lawn violets or violas? The violets in the catalogs are so cute, but I don't want something that gets out of control.
Weerobin, That white viola certainly has unusual leaves-nothing I have seen before on a viola or violet.
Do you mean these? They are Johnny-Jump-Ups. Once you have them, you have them forever. I'm not sure if they are annuals, like pansies, or short-lived perennials. Either way, they pop up all over the place in early spring, wherever there is room. I pull them up after a while when it's time to plant other things, but some I leave. If it gets hot enough they disappear, but they're back again in the spring.
Pfg: I don't really know what kind of violet/violas they are. They just come up Everywhere and difficult to get rid of in the gardens. They will take over a garden. I have kept them out of my garden/s, but the lawn is a lost cause. I like them in the lawn, but if they were in my garden-they would simply take over. Your little Johnny Jump Ups are quite cute. I don't think that is what I have. I will try to take a picture this spring. I have never bought any kind of violet and yet they're all over my lawn in the shady area.
It doesn't sound like yours are JJ's, maybe more related to my white violets, which are true garden thugs. In early spring I have masses of Forget-me-nots and JJ's everywhere, covering what would have been bare earth--so cheerful and springy! I can never have too many at that point. And I always speak very nicely to the ones I have to yank when they get in the way of spring planting, etc.
I direct sowed them from seed 5-6 years ago, don't remember exactly when. Now or very early spring should work, just scratch the surface of the soil and sprinkle the seeds around. They self-sow prolifically, although it took mine a couple of years to start popping up all over.
Johnny jump ups can be something of a pest after a while. I seem to recall getting my mom to send seeds on 2 or 3 occasions until I finally got them established (by tossing the seeds into the beds). After a few years, they can get so thick as to prevent other seedlings from coming up. On the other hand, they certainly ar cheerful and immensely variable, and few others things bloom so early and so late in a cold climate.
I do love them, but that's why I pull them out once other things need the space. One place I like to leave them for a long while is around rose bushes. They really help with weeds, and look so sweet poking up through the branches. Eventually, though, they get too thick and sprawly and out they go.
