Thanks! My sister was able to add that it is euonymous americanus--"Hearts a'busting"

Thank you! This site is wonderful for quick identification. I've found a couple of other plants I wanted ID'd in previous posts too!

Thanks for the replies. However I am doubtful it is any of the ones mentioned. Definitely not an iceplant which at least has foliage year round. I might be wrong and maybe it is a type of poppy after all, but I don't think it is the California poppy which seem to be bigger and flowers way longer. The flower shape seems to be more like a poppy than a daisy (but I must say I have terrible vision). I will try and get a picture if I can. Some patches are pure (yellow or orange only) but you can always see mixed patches in the same vicinity. The flowers are very dense and its almost hard to notice the foliage.

Ashley - you really can't compare varieties. Early Girl, as an early variety, is much more tolerant of both cooler tamps and temperatures fluctuations. But it would be affected just like the others if it was over-fertilization. So I suspect, given the temperatures you mention, that the mid-season varieties are just lagging a bit behind in fruit set and a bit confused by the recent feeding. I too have tons of fruit set on all my various early varieties but thanks to weather extremes my mid-season varieties are dropping some blooms just like yours. We both just need to be patient and in the meanwhile, make sure to not OVER-water or OVER-feed as both are stressful to the plant. Wait on any further feedings until those plants set more fruit, ok? Feeding them just triggers them out of fruit set mode and back into growth mode. Trust me, you will get all of the yellow pears you could possibly want in time as they are an exceptionally prolific plant. ;) Dave
