These flowers are so different looking that you probably wouldn't think they're even from the same genus -but they are both Impatiens.
Towards the end of summer, I bought two six-packs of white bedding Impatiens (Impatiens walleriana) from Wal-Mart for 80 cents total. What a bargain! I put them all in one big pot and they've really taken off. I know there's hardly any chance that they'll cross with the native Jewelweed ( Impatiens capensis), but what's it gonna hurt to try.First picture shows the two radically different Impatiens flowers. The top flower of jewelweed has its spur petal split open so that you can better see the internal spotting.
In the second picture, I used "Paint" and crudely cut and pasted pieces from a picture of dissected flowers to show the corresponding parts of the two.
