I should be receiving a nymphaea pygmaea Helvola in the mail in the next couple of days. This is my first aquatic plant so I have a lot to learn .. the main thing for now, is how shallow a pot can this be grown in?

You will want a pot that is wider than deep. This lily can easily be started in a pot no more than 1-2 quarts large, but most start it in a pot that is 2-5 quarts. A pot of 8" wide and 5" deep will hold 3 quarts.

BTW...I checked out your garden website....beautiful!

Anne, your lily is a miniature so you can safely err on the smaller side for this one but definitely wider rather than deep. Be sure to plant the rhizome against the side of the container with the growing tip going towards the middle.

Thanks Alice. I was planning to use that clay cat litter "special kitty" you get a walmart for the substrate .. is that ok or should I use something else?

Here's a picture of the bowl I'm going to use .. let me know if it's suitable.

I have seen Helvola used in bowls about that size and your bowl is very pretty. I can't wait to see it when the lily is blooming. As to the WM kitty litter be sure to get the stuff without any additives like deodorant or anything. I use the API Pond aquatic plant media mostly because my son gave me a 25 lb bag of it. I like that it does not break down and clog the filter like the kitty litter can but you will not have a filter to worry about so go for it.

Thanks for the info .. got the bowl at a thrift shop for 5 dollars.

I recommend the API Pond aquatic plant media too. It's much better than using the plain kitty liter. A little more expensive, but worth it. Post a pic of the lily when you get it established.

It came and has some nice roots. I wasn't able to find any of the API Pond aquatic plant media so I ordered some from Amazon .. will the tuber be ok in the glass of water until Monday and does the glass need to be taller to completely cover the leaves?

Why don't you just float it in the bowl, you can add the medium later. I am afraid the leaves will dry out if they are not floating.

Water lily is growing and putting out leaves! However, I'm starting to detect a greenish cast .. algae.

It's outside on a table that get 2 hours of full sun starting around 1pm. I pull out any detritus like leaves and such that fall into it and put some mosquito dunk in it. It's been raining every afternoon as well so it's getting a lot of rain water. Is this a suitable environment and how do I stop the algae?

You will get algae until the leaves cover the surface and shade the water. Perhaps you could drape something over part(s) of the bowl until more leaves grow or move the bowl to a less sunny area. Crossing Fingers! I suspect you might still get some algae as light penetrates the glass but I think a green "lining" would be attractive, you'll still have the look of the crystal on the outside.

Xeramtheum, hi! Your post made me join the forum. I have raised fish and waterlilies for over 50 years, and hate to see someone who may be new to watergardening making a mistake. That is a beautiful bowl. I would use it for salad. I don't have a picture of Helvola, but I do have a picture of pygmaea Rubra, which is the same size. Since you planted it in a pretty glass bowl, and not in a pot, I am wondering if you plan on just using the bowl for your watergarden. It won't work. On sites like Pinterest, you can see beautiful little lilies growing in glass containers like brandy snifters and such. It makes a lovely photo op, but in reality, lilies will not grow like that. Even little ones like Helvola need space and a good growing medium. They constantly produce pads and blooms. They are heavy feeders. I personally wouldn't use kitty litter or the commercial waterlily medium that is made for growing lilies, although, I know a lot of people use it. I have also seen lilies planted in coconut husk....another not so great idea. I don't think you can improve on tried and true methods. Lilies grow best in heavy garden soil. Like you would dig up in your yard. You put a little fertilizer in the bottom third of the pot you are planting in. Place the rhizome so the growing end can grow across the pot, and the end that was cut off, up against the side. Cover it with a little of the soil and top with coarse sand....if you don't have destructive fish....or pea gravel (best). Be sure the growing point is not covered.

If you do not have a pond, I would go to the nursery center, or Walmart and buy a large flower pot that has no hole in the bottom. The larger the better. You can buy some large, glazed pots that are very attractive. Two foot across the top would be okay. Put your soil, or planting medium in there....don't forget the fertilizer. You can use something like Osmocote. They are little balls....I think they are called prills. Put in the bottom third, and mix it up. About a tablespoon or a little more. Top with the rest of your soil. Plant your lily and add something to keep the soil from being disturbed. Pea gravel is best. Don't cover the growing tip. Very carefully fill with water. You can place a newspaper over the lily while filling to keep it from getting washed out but it you do it right, and are careful, it won't. Make sure it is a sunny location. Stand back and admire your work. Helvola is a lovely little lily. It won't disappoint you, if you grow it correctly. The blooms will be about the size of a half dollar.....if anyone remembers a half dollar. I am posting a pic of pygmaea Rubra to show you the size.

I hope you don't mind me jumping in here and trying to be helpful. (By the way, the pattern of your big bowl is Wexford.) Thumbs up

Thanks Marilyn! I'm ordering another mini lily and I'll plant it according to your directions and see which one does best.

My Helvola is growing like crazy along with the algae! Do mini water lilies mind having their roots disturbed? I want to toss the substrate and put in fresh. That would involve removing the tuber and floating it for awhile. Is there an algaecide that is safe for water lilies or a way to control pH that would discourage the algae but not upset the lily?
