Additional comments: One of the most consistent cool season bedding plants for the Phoenix area. Set out transplants in early October at about 6 to 8 inches on center. D. deltoides used in combination with Lobelia erinus make a wonderful color combination for residential and commercial entryways during the Phoenix cool season of late October to mid April. D. deltoides sometimes reseeds and might survive until July in Phoenix if planted in an eastern exposure location with copious mid-day and afternoon shade. There are a plethora of cultivars of many single and multi-colors, new ones are introduced each year.


Noteworthy cultivars examples:
'Albus' (white)
'Vampire' (deep red)
'Zing rose' (scarlet red)
'Microchip' (multicolored)
