I would say try it. You do get some sun in the bed and it should be enough to help. Bruno is a good choice it is soposed to be a tougher plant then the others. Leaves on these can be huge with lots of big flowers.

Thank you Mr.Impatiens! I was hopeing to hear from you!

The Brunos this year have been a bit funny. The bed they are in is literally 1/2 sun 1/2 shade-as in the back half is all shade, front half is all sun, and this bed is only 3 feet deep!. At first, the best looking plants, and best flowers were in the back (in the shade). It took a really long time for the front flowers (in the sun) to really take off. I mean, there were weeks where the front plants seem to suffer dearly in the full sun, were barely growing, and the back half was as very lush and a good 6 inches taller than the sunny ones. Two months later, the shaded ones have stopped blooming and the sunny ones are just a solid bed of color. The sunny impatiens are extremely floriferous, and the shaded ones have stopped blooming. The shaded ones have also grown much taller and leggy compared to the front ones. I am certain there are other factors contributing to this, for one thing I have the plants way way too close together (I had done this on purpose as an experiment). I am sure another factor could be needing pinching; until I had read this forum I never realized impatiens needed pinching, they always were self cleaning in my experience, although I am sure pinching helps everything. Another factor could be from when I grew them as seedlings. Some of my Brunos got pinched, some of them didnt. The reason why is because I had noticed that other impatiens I had grown took a real real long time to branch out and flower after having been pinched as seedlings. So I did this experiement to analyze this. As a result, all of the Brunos (pinched or not) flowered at the same time! This surprised me, I had thought the unpinched ones would flower much much sooner.

Bruons have very large flowers, as do all impatiens I have grown. In fact, I have never grown the tiny flowered standards that you get at the nurseries, either that or I am doing something wrong, because all impatiens I have ever seeded ended up with large flowers. I am certain this is a variety issue.

Anyone else have experiences with Brunos? Do you have a better suggestion for this bed, as far as varieties?

I need to correct myself.

When I was talking about "pinching". I had said that I hadnt realized that impatiens needed "pinching" I actually meant "deadheading". I have never really noticed dead flowers that needed to be deadheaded. When I was referring to pinching, I meant exactly that--pinching the growing tips when they were growing on as seedlings.

Just wanted to eliminate that confusion, as I know many people get this term confused.

Can you take some of the limbs of your trees away? A little like pruning, but judicious editing of branches will allow more light to filter into the space, thereby creating light, dappled shade rather than heavy,dark shade. Am I making myself clear? a good arborist or landscaper should be able to prune out some branches and help out the entire situation. Capish?

Impatiens balfourii is one that will do quite well in fairly deep shade, and summer sun after 6 pm shouldn't be an issue for most shade plants as long as they are not also drought stressed.

The kikyo snowflake "Morning" glory i grew in shade blooms :P i live in an apartment, the only place i can do gardening is the balcony.. There are tall buildings surrounding my apartment. My garden gets a direct burning hot sunlight at noon for only 1 hour, the rest is blocked by those buildings.. But my morning glory blooms! Strange.. because, its a morning glory! I never thought it will bloom without any morning sun..
