Open pollinated hosta often set seeds. It is normal. Mostly you will get plain green ones but sometimes you will find a yellow or blue. If you have any streaked hosta you could find streaked, variegated or solid colored babies.
I had that all the time with the Midnight Ride, I just gently dig them up and plant them somewhere else, like under the tree. They are all green, nothing special. I don't get them anymore since I removed the fertile hosta's, I have not had nothing that fertile since.
So what kinda Hosta do you have? Do you know where the seeds are coming from?
They are just sports, The hosta's do not come true from seed. (Except maybe one.) They have to be divided, so if you see something cute just pot it up and if you see the plain green ones just toss them, they are not worth getting stressed out over. If you end up with a nice sport you can divide it later and make extra plants from it, if you want. :)
Virginiarose - NO, they are not sports - they are hybrids. Sports are a genetic change in a plant, not a seedling. But you are correct in that they will not come true to the parent plant. The vast majority of hosta seedlings should end up culled and composted, but once in awhile you will get a surprise and that can include variegation; so it's wide to keep an eye on them.
I have several interesting seedlings. One is fully variegated - a reverse of the parent plant which was 'Last Dance'. Another is variegated at this time of year, but the centre of the leaf will darken during the summer. And I have two plain Jane seedlings which I've had 3-4 years which THIS year put off a sport with variegation/streaking. I'm definitely keeping those variegated/streaked eyes to see what they become.
Oh, I forgot the sport is the thing that grows on the side. These would be seedlings that are hybrids. Got ya!
I must not have many fertile Hostas right now because I have not seen anything at all since I got rid of the Midnight ride. However the seedlings I did save are still growing under the tree and never get watered or anything, amazing but just plain green.
I would like to see yours sometime! I might see something this year, I did add a lot of new ones. :)
Green isn't bad! I have a number of op Hosta montana seedlings. They are going into their third year and they are magnificent. I love montana and have several variegated varieties as well. Alvatine Taylor has produced a number of blue seedlings this year. They all apear to be similar, but the shade of blue green is very pleasant,
Good, glad to hear. I do have a Montana and will look forward to that. Mine are not pretty but they are where nothing else will grow. Thanks for mentioning Alvatine Taylor, I forgot to put that on my wish list. :) oh, would love to see those seedlings when you get the chance.
My only fertile hostas seem to be Sum and Substance. It has thrown several babys which are really small and have taken years to grow and don't appear to be able to achieve the size of the parent plant. They have the S & S color and leaf shape, but so far, not the size.
I don't know what mine are... I figured just Royal Standard--medium size, plain green with no variation. My front yard is 100% groundcover with some hostas mixed in, but each year it becomes MORE and MORE hosta-filled. I didn't even realize how many were coming in this year until it was too late. Now they're all out and HUGE and nearly covering the front yard. I must have 75+ of them out there. It's completely ridiculous! I never realized hostas could self-seed like that. Mine are truly prolific breeders.
It seems difficult and messy to remove these full plants. Would it make more sense to wait until next spring and try to dig them out when they are just coming in? How do I know which ones are "fertile" or not? Is there any way to tell? If I could pinpoint the main source(s) of all these babies, I'd take them out as soon as possible.
you could religiously deadhead every blooming flower stalk off of these hosta. No flowers-no seed. Let them bloom but take them off directly after. be sure to remove these stalks from the area and don't compost them. Thin out some of the mature plants and give them to your local garden club or church bazaar for their plant sale. But removing the flowers is the only way to prevent the seed.
