Dietes Species, African Iris, Butterfly Flag, Fortnight Lily, Peacock Flower

I have 9 bi-color iris in the ground 5+ years. Very tough yet reliable plant, no fussing, water once a week on drip during our severe dro...Read Moreught the last two summers. Not bothered by cold. Survived with a shrug two winters ago when it never got above freezing for 3 days.

Mine grew into large clumps so I unceremoniously cut them in half with a shovel and transplanted the other half. All survived fine and recovered nicely in one season.

One person wondered what part shade means in southern Arizona. I lived in Las Vegas for 30 years and my sister lives in Tucson so am familiar with desert gardening challenges. Part sun/shade in So. Az means:
(a) under a shade tree such as Desert Museum Palo Verde that allows dappled sunlight
(b) morning sun, afternoon shade (east side of house)
(c) avoid planting in open (like you would a Bougainvilla). The So. Az sun is a killer and only the strongest survive.
(d) weekly watering on a 4gallon drip for 30 min should be fine. The difference between the same plant surviving in the hot south Texas summers and dying in So. Az is our humidity.

Finally, don't know if an issue in Sahuarita, but deer have never even nibbled on mine and we are in one of the worst deer over-populated areas in the country. Good luck with them.

I live south of Tucson, and purchased a Dietes Bicolor, but the plant tag says it needs 4-6 hours of sun a day.

Some othe...Read Morer sites even said, "doppled shade."

The worst part of all the different gardening websites is a lack of knowledge about hot Arizona, so what does part sun mean? Is no sun in the winter OK, with part shade occurring in the summer when the sun is directly overhead?

If the bicolor is planted in the open, in direct sunlight, won't the summer sun fry this iris? If so, should it be placed on the east side of a west facing home, so it only gets morning sun? I would love to put it next to my pond, but in the summer, the pond is dry, and we are in Seattle.

Any advice on this iris would be much appreciated from an Arizona grower, or gardener

These plants grow like weeds in Camarillo, California. They are tough and dependable bloomers, but self sow everywhere! Often by the ti...Read Moreme I see their stiff strap like leaves coming through the daylilies or agapanthes they are well rooted and quite a chore to dig out.

I planted several of these many years back. They just keep on growing and spreading. They didn't flower at first and I was disappointed...Read More, but when they started to flower, I was amazed! The flowers are at the end of a long stem and they dance in even the lightest breeze. I have some blooming in partial shade and several blooming in full sun. They are exactly the same plant and they have all adapted beautifully to their separate environments. They have experienced overwatering and underwatering, fertilizer and the lack thereof, and sometimes the unwelcome attention of my dogs, and they keep on thriving. I've got seed pods now and I am so excited. Even without flowers, these are willowy and delicately shaped, but extremely hearty. I highly recommend them. Just love them and they will return the love!

My Dietes bicolor plants took several years to bloom after I planted them. This year they started to bloom in the middle of February whi...Read Morech is quite early for them to bloom. Last year, they bloomed all summer and had some blooms into the fall. I seldom water them and have never fertilized them directly. They have received fertilizer from a hanging basket above them that I add blood meal to each year before I plant pansies in it. If the plants never bloomed, I would still love them because of their lovely evergreen foliage. The only problem I find is that I have to remove fallen oak leaves from between the blades each year because I am afraid that they will cause the plants to rot. Dietes bicolor is one of my care free plants that provides beauty year round.

The guy who did our landscaping planted several clumps of these, but said they were bearded iris. They didn't do anything for a couple ye...Read Morears except expand. When they bloomed I was very pleasantly surprised to see this type of iris, one I had admired for a long time but didn't know what it was. The only unfortunate thing is that when I needed to divide a huge clump, it took a very long time for the main clump to bounce back from the stress. When I say a long time, I mean a couple of years. Also, the divisions I put into containers all died. I think I may have overwatered them. I like these evergreen iris because the foliage is very architectural, and when it isn't blooming looks like a very nice ornamental grass. The flowers are a nice bonus, though the blooming period doesn't seem to be very long here in the SW.

It has never bloomed. I have moved it to part sun, full sun, shade, you name it. It has gone with a lot of watering, and it has gone with very little watering. I just can't get it right! I really wish it would bloom!

That said, the blooms are a striking saffron yellow. D. bicolor is a tough, attractive plant that has no apparent proclivities towards disease or insect damage. My friend who lives in a cool microclimate here reports that this year, when it got down into the mid-20s, hers died to the ground. In seven years of growing these, I've never had mine even browned by frost.

The leaves are bladed but darker green, thinner, taller, and much more flexible than traditional Iris. They are neither ornamental nor unattractive; non-descript would be a better term. The flowers, however, are very nice and do indeed look something like a miniture iris with white petals and dark markings.

I understand that they tolerate full sun, but mine are planted in light shade and they do very well in that location. They are very low maintenance--I typically water them in the process of watering the lawn, but nothing more. I also find that the use of a bloom-promoting fertilizer will cause the number of blooms to explode!

I bought 4 of these African Iris that were marked Dietes vegata, but turned out to be Dietes bicolor.

It´s a very atractive flower, specially if you see it closely (the light yellow doesn´t appeal me from a long distance), because you can see the orange lines ans marks between the light yellow sepals and the black spots.
