Companion plants for a large container with hosta?

Norristown, PA(Zone 6b)

I have a very large ceramic container that I am going to plant a (some?) hostas in this weekend and would love some suggestions for a (some) companion plant(s)...... The container is a bright lime green - and I can choose whatever color hosta I want from my ever growing collection. The companion plant(s) can be annual or perennial (I will have to buy them). The container sits in a shady spot that gets morning sun. I would love to put in something that will flower - but I also want to plant a big hosta and have it be the focal point of the container- so I am not sure there would be room for anything with flowers. Something that spills over the edges maybe? Any suggestions would be great. Thanks!

The day will come when that hosta needs dividing so I would suggest a pot within a pot to make it easier for you eventually. As for a companion that spills over the edge, I can think of nothing more attractive than Hakonechloa.

There are some colorful Calibrachoa that would look nice under a hosta! I always have to put some in a pot somewhere in the yard!

Thanks Pirl and Rose. Both are great ideas. I actually have a pot of Hakonechloa that didn't get planted last year. Hmmmmmm.....

I looked at calibrachoa at the nursery today for my window boxes - I thought it looked so pretty. They said it liked sun - so I am not sure it would work with only some morning sun. But I am going to get some for my window boxes - so I might just have to buy an extra just in case. We have frost warnings tonight, so I didn't buy anything - just looked. I am going back next week for my window box purchases - once the frost-fears are gone. What a crazy spring!

I planted them in a pot that was in my hosta bed and they did great. That spot gets bright morning sun, though.

Beaux - the Hakonechloa is easy to divide with a sharp knife.

Torenia is a flowering annual that spills a bit and likes some shade.

A Blue Green Hosta such as Tokaduma Aureo Nebulosa would set off the lime green pot very nicely.

I vote for impatiens. Always look good with my hostas. Many colors and sizes to choose from and sizes to choose from too.

I love Torenias too. I have a order coming in a month.

Wow, thanks everyone for your ideas. I was thinking about a nice blue hosta. I don't know why I hadn't thought about impatiens and I am going to look at Torenias, too! I can't wait to get started this weekend! I will post a picture when I am done.

Depending on the size of your pot and the choice of the hosta you could use the following:

1) the Hachonachloa (spills over) suggested by Pirl or red blood grass (spiky and taller for vertical interest). A blue oat grass or festuca "Elija Blue". Both tolerate some shade.
2) a heuchera/heucherella to complement the hosta. Some of the heucherella spill over
3) lamiums definitely spill over. There is even a lamium with yellow foliage.

I've used these perennial companion plants in pots and transplanted them into the ground at the end of the summer.

Speaking of impatiens, you might look for the "Fusion" impatiens, which have a more trailing habit than the regular ones. I like those a lot.

Does the pot have lots of drainage? If not, keep it out of the line of thunder storms or you can end up drowning everything in it.
