High temperature germination

To get straight to the point, is the germination of impatiens walleriana inhibited by high temperatures? (~90F)

I live in the tropics where that is pretty much the average (indoor!) temprature. I have had good success rates with other annuals using the baggie method (with coffee filters and placed under "daylight" T5 tubes when necessary), but just can't seem to get any germination at all from the impatiens seeds. I started with a packet of "Dazzler" from an eBay seller, and when none germinated after more than a week, I assumed that it was a bad batch. Tried some "Baby Pink" from a different seller, but still nothing!

I know certain annuals such as petunias do not thrive in hot temperatures, but I was hoping to get at least *some* germination from these impatiens seeds to try my luck at potting them outside ;-)

RE: High temperature germination

Impatiens being a shade plant will not flourish in high temperatures. Even if you got them to germinate it is unlikely they will do much outside in the heat.

You have so many tropical plants that others can't grow pick one and grow that. I would dearly like to grow some plants that just won't tolerate my climate. That is the nature of plants and we gardeners have to adapt
