"Sunflower" has thrived in my zone 9B garden in the Sonora Desert south of Tucson, AZ. "Sunflower" is a relatively large Echinopsis hybrid. Balancing the amount of sun exposure, fertilizer, and water to achieve optimal growth can be difficult with any Echinopsis hybrid. "Sunflower" does seem to be less "fussy" than other cultivars I have grown. As cacti_lover has written the flowers are large. They are very beautiful as well.

This plant grows pretty fast if given plenty of light, water, and feeding in spring and summer. It benefits from lite shade in the afternoon during the summer heat of the desert. The yellow flowers are 5"-6" across and can be profuse. The petals are narrower than those of Trichocereus 'California gold'. I recently cut off the 2' long main stem into two pieces so I can make two new plants out of it. The cut areas have to be dry before planting. I have no digital photos of this plant at the moment, but when it blooms in April, I'll upload a few.
