It's too bad that you cant go just a tad bit shorter than 2 to 3 feet, I had lots of suggestions for you that stays with the same one plant, but with color varations. One suggestions was to go with the Cosmic cosmos--all three colors red, orange and yellow which are totally stunning and vibrant mixed together. And incredibly easy to grow from seed! Another suggestion was Magellan zinnias, which will grow like dwarf hydrangea shrubs smothered with handsized blooms that last for months. I had blooms that did not need be removed for 4 months, I kid you not! And there is just about every color available, coral, ivory, yellow, pink, scarlet, cherry, orange, salmon. I am growing over 400 of these this year. Another suggestion was a mixture of Celosia 'Fresh Look' colors in red, orange,and yellow. Most people hate celosia because they have never had good luck with keeping them going, but the Fresh Looks are very stunning, lush, healthy plants that get just under 2 foot tall, if I remember correctly. Another suggestion was to do Gomphrena, in a mixture of colors. Gomphrena, if plants are kept together and properly spaced will grow to a 2 foot tall airy "shrub" that stands up to rain, drought, etc. I grow the "All Around Purple', 'Strawberry Fields', and other colors from Park Seed, including white, rose and bicolor rose. Dont underestimate those small colored balls! They can REALLY make a huge standout, if they are grown correctly. I second the idea of using Profusion zinnias. These are like the perfect daisy like flower! Also, the blooms did not need removed for 4 months, available in colors: cherry, white, orange, Fire (reddish orange) and Apricot (my favorite). Very easy to grow from seed. You may want to check into the Tidal wave Petunias. If you space them about 2 foot apart, they will spread out like you wouldnt believe and grow to about 2 foot tall. I have never seen a petunia grow like this before last year! Though, the silver would blend right into your house color, but they do make a purple, hot pink, and cherry color that I will be doing this year. Tidals have a massive branching system to them. Do a search on gardenweb and you will find lots of pictures and ideas for them.

Impatien/touch me not are the only seed pod that I know of that bursts like that - There are many types of impatiens out there - you could pose this question to the impatiens forum if you don't get an answer.

So no flowers for me? That is quite alright as I have my hands full trying to get my Jades to flower... not sure if I could take on another "project" :) Good idea, Costarico, I have been looking into that after seeing pics of much fuller ones. The single stem look of mine is nice, however, I do admire the bushier ones. I would propagate the top part if pruned but I'm not sure if now is the best time to be doing so? When you say "cut down" about how far do you mean as I wouldn't want to cut down more than half. Thanks to you both.

Its, perennial vinca. Sounds like you have the white variegated variety (I've got the yellow, my,self). MOW it, it will keep it in check and really make you feel better. You won't kill it, I promise. Now, if you want to kill it, why not try and see if anyone on the plant exchange forum will give you something you want for it instead. If you trade away much of it, but still want to kill it, ask again and I'll tell you how. ~Chills
