Can any of these flowering plants be kept in pots and indoors?

Peace Lily will do nicely indoors as will miniature Roses.

As for Lily of the Valley and Lavender, I have never personally attempted growing these indoors. I say, experiemnt. Get some Lavender plants from a garden center or nursery and try potting it for indoor growing. Same with Lily of the Valley. You could pot up some and see how it does. You just never know what might survive in the right conditions. I have been overwintering my Impatiens for years. I bring their pot inside in the fall and set it outdoors in springtime. They have lived at least 5 years this way. Most gardening enthusiasts don't think of Impatiens as houseplants. They do great indoors over the winter :)

Hello Cay! I know what it is like to want to have flowers but be limited in space and windows. The peace lily should be okay indoors. Have you considered begonias? The Rieger begonia has gorgeous flowers and mine grows well inside. African violets are a favorite. Have you seen anthuriums? Spider plants are fun – they have lots of “babies” to tend. Cyclamens and holiday cactus can bring some blooms to your home. Orchids come in many varieties and some have a wonderful fragrance (see below) . Some of these bloom in cycles – do your homework so you will have flowers all the time!

Check out your local home improvement or garden center and the folks can help you select the best varieties for your area. My grocery store even has great selections. Best wishes!

I live in SE QLD and I've grown some of these indoors here it can get very frosty in winter below 0 sometimes so they would be OK for Melbourne

Have a look at this site it tells you all about how to care for the Peace Lilly indoors.

Happy Indoor Gardening

The only two flowering plants I can think of that can live indoors are African Violets and Orchids. African Violets are much easier to have, care for and produce flowers all the time. Both require indirect light and not too much watering.

Indoors, no, you will struggle with all of these both in light and rootspace. If you have a very bright room, though, you can probably force irises and other bulbs in pots.

You may also consider other tropicals compatible with indoor planting:

Ranunculus is supposed to look like a tulip, rose and poppy (depending on whether it is a young, older or old bloom), if this helps. Amaryllis is stunning, fast growing and dramatic. Go red.

These flowers are sometimes sold cheaply at a supermarket. See if you can live with them this way.
