hi there
miniature & dwarf waterlillies are perfect for you, I would say.
joanna pring(mid to pale pink)
nymphae tetragona (a small as a matchbox flowers) in white
perry baby red (almost crimson)
nymphae hevolva (palest yellow)
all these are only 1/2 to 1m accross
As far as I know all the night bloomers are a lot bigger in spread.

google is your best friend
I might add that I am in australia so i don't get the cold here where I am . so some of these may not be suitable for you. But iam sure that if you did some research on the internet for your area you will find what you are looking for . I purchased all of mine through the internet and they have been great , Sorry my computer is playing up at the moment so I cannot post pics successfully.

some of the usa people may give you a few others that would do well in your area

A link to my favorite lily site is below. I particularly like it because in the individual plant descriptions, it lets you know which lilies are the more prolific bloomers. The prices are also reasonable.

When you get to the site, on the left of the screen, there is a red sidebar of categories which includes Pond Plants.

Here is a link that might be useful: Aquariumplants.com

Fantastic website Nancy! Thanks! I've picked out Andreana and Red Flare. Can't wait to get them growing!

Hi Jenny, I was in the same boat, having never grown waterlilies and having a pond that is just a little bigger than yours. I couldn't decide which color I wanted most, so I chose a changeable. I chose a Clyde Ikins waterlily. I received it last fall right before fall arrived. I left it in the bottom of the pond, and a few weeks ago when it started sprouting new leaves I fertilized it. I love the color of the leaves and have 5 blooms getting ready to pop to the surface. I can't wait. Here are some pictures.

Mazela, I had no Idea you were in Australia. Wonderful. I knew we North Americans had a lot of UK visitors but never knew that of you.

I'm curious, what do people do with their water lilies when they add or divide. After a while do you just give some away?

I ask because I have a pond that is two pools, upper & lower, with the lower being larger in depth and surface area... I call that my lily pond. It is about 17 ft x 12 at the widest dimensions... I figure it is about 150 square feet.

My hardy water lilies are:
Marliacea Albida
Moon Dance
Joey Tomocik
Texas Dawn
one unidentified

Yeah, they're all white or yellow flowers.

I've divided some and have about nine now. They could stand to be re-divided if the clump emerging from the large, shallow container is still the case, as it was last autumn.

What specifically do you do with your extras? Do you stop dividing?
If you trade, where do you trade? How?

Hi Vickie

Your pond is gorgeous! The more pictures I see of it, the more pond envy I get! LOL

I love the color of the leaves on your lily! Here's hoping the lilies I ordered on Monday will do as well!

Thanks for sharing your pictures!

Hi Jenny,
If I were you, I'd start out with just 1 med-large lily. My "pond" is 5x5 and one lily completely fills it out and could even stand more space. Or....go with 2 small ones. But whatever you choose, I'd get just one the first year and see how much space it takes up. I had 2 med-large lilies in one 5x5 pond and it wasn't pretty. They just get too crowded to be attractive.

I've grown tropical lilies here in zone 5 and had good luck in the summers that were VERY hot. however, last summer was cool (in 70's) and they did very poorly. They really need alot of heat over several months.
Good luck!

My recommendation would be the hardy Paul Hariot.
Its a smaller lily, blooms really well, and the flowers stay open later in the day for me. I've had mine in smaller container water gardens in morning shade and afternoon sun.

Last season I ordered some waterlilies online, can't remember from where. They were healthy but in the very first stages of growth, and it wasn't until August that they really looked good. So I'm a little questioning of the internet approach.

That said, I may have to rent a car for over $70 to drive to Long Island where there are actual waterlily stores! (I am not a car owner).

(Unless you were just looking at that site to get ideas of what type you want, but will be buying them elsewhere?)

Thanks everyone for the info on the water lilies!

I did end up ordering some online since I live in the middle of nowhere and the nearest greenhouse that would have any sort of decent selection is in the Minneapolis/St Paul, MN area which is 2 1/2 hours from my house.

Interestingly, though, I do live within 20 minutes of 4 HUGE greenhouses. One has a limited selection of pond plants. SO, thanks for the heads up Liz on the internet lilies. I just might pick up a lily that is already growing from the greenhouse (though it hurts my heart to pay $31 for a plant!!).

I'm within a week of getting the pond completely finished and up and running. I'll be sure to post some pics here when it FINALLY is done!!! :-)
