Hi clysta, I didn't see your post until I was looking for something in the Gallery section today. I don't know why the landscapers won't leave our flowering shrubs alone. Just when they get ready to bloom or are forming the budwood that produces flowers they get buzzed. This is a 3-fold issue. The shrubs usually grow too large because they are overwatered in common areas. That forces the maintenance crews to trim to keep them within bounds. Also, it seems the landscapers want to leave evidence that they actually visited the property per their contract - hence the pruning. Lastly, shearing takes less time for the crews. If Cassia shrubs (Senna artemisioides is the most common) are being watered correctly they only need to be pruned once or twice a YEAR. Because they bloom from late December through April the best time to prune is in late April or early May. The seed pods can be removed at this time as well. If they are pruned in the fall it interferes with the bloom cycle and you may not see the attractive butter yellow flowers which are slightly scented. Desert shrubs should never be sheared. It creates a dense layer of leaves in the outer 3 or 4 inches of the shrub that prevents light from reaching the center of the plant. As a result, the middle of the shrub is bare and dead looking. It also destroys the natural form of the plant and reduces flowering. A better pruning procedure, and one that is endorsed by the International Society of Arboriculture and is included in the ANSI A300 Pruning Standards, is called 'selective' or 'natural' pruning. To reduce the size of the plant, hand shears are used. Yes, this takes more time, but if the watering is correct it only needs to be done once or twice a year. You live in Casa Grande right? I know a landscaper (and certified arborist) that works in Maricopa. His name is Doug Duport and you can reach him at dsduport@gmail.com, www.agreenerleafllc.com, (520) 586-3255. I'm sure he could make a presentation to your HOA if necessary. I hope this helps. I'm going to send a pruning guideline to your email address. I also have a template for a landscape contract that many HOA's have used as a guide when hiring a contractor if you (or your HOA) need it.

coreopsis? i think those are the ones i see blooming this time of year. i don't know the species- they are fine leaves like 'limerock ruby' and those type of cultivars. we have them here on buffaloe in garner, too. they are small- like 1 or 2' at most, and the flowers are small, too- about 1". neat appearance. if the plants are taller (2-3.5') with raggy orange cosmos type foliage and more of a blowsy shape they would probably be bidens. which is considered a weed, but i love them and grow them in my garden. BUT there are so many flowers that have that single yellow daisy flower that bloom right now, it's hard to sort out without a picture. the size and foliage is key.

I've had that too with some of mine. Especially Taratahi Glo. It starts blood red, with a bit of yellow; then washes to more of an orange. This year, it started late; and started with the orange flowers. I believe it is weather related. I think some dahlias thrive on warmer temps and more sunlight. When mid August, september roll around, my neighbors giant Maple starts to shade my yard for most of the day. That seems to dampen the color on some dahlias. Just my theory anyway...

The problem is that there are a hundred or other and I don't think than any one on the forums has enough experience differentiating them. So Oenothera may be as far as you can get...
