DH = Dear Husband in the standard internet lingo, and I assume you are making a joke, so I'm laughing with you. Feel free to use it to represent Dumb Husband if you choose, but not because of the cilatro issue. : )

Cilantro is a cool-season crop that begins to bolt once temperatures hit 65 degrees, although it can hang on for quite a while if the temperatures are fluctuating a lot from hot to cool and back again in springtime.

To get cilantro in the summertime you can try sowing seeds (available on seed racks in stores or from any online seed seller) every couple of weeks and growing it in morning sun and noon through afternoon shade, but you have to harvest it young and small before it bolts, and keep sowing seeds every week or two for a perpetual harvest. Or, you can grow it indoors under grow lights if you keep your house cool enough.

One regional seed retailer that normally ships pretty quickly and has reasonable prices is Willhite Seed, based in Poolville, TX, west of Fort Worth. They have the "Long Standing" variety of cilantro, but have it listed under coriander. When you harvest cilantro for the leaves, it is indeed called cilantro, but when you let it (ha! as if you can stop it, which you cannot) go to seed, the seeds are the spice coriander. So, in that sense, it is a versatile plant---providing us with leafy cilantro early in the season and the spice coriander later in the season. Even the varieties of cilantro bred to bolt more slowly just don't last long in our heat.

Here's a link to Willhite:

To grow it in Oklahoma, think of it as an early spring and mid- to late-autumn crop because out heat makes it bolt awfully early, usually well before summer arrives.

There are at least two heat-loving herbs that taste similar to cilantro (but not the same). They are culantro and papalo. I've grown both, but don't grow them any more. They don't taste enough like cilantro for our tastes. Your taste buds might like them, and you won't know if you don't give them a try. Seeds of Papalo are easy to find at many seed companies online, but culantro is a little harder to find. I bought my seed for it years ago from Nichols Garden Nursery--probably 8 or 10 years ago. I assume they still have it.

When I want cilantro in the summertime, I buy it at the store. There's enough weather-related problems to fight here in OK all summer long as it is so trying to keep a cool-season crop going in immensely hot weather is not a battle I'm interested in fighting.

If you do let your springtime cilantro flower and go to seed and just leave it there, the seeds will fall to the ground and give you new plants either the following fall or spring. As a bonus, cilantro flowers do attract lots of pollinators and other beneficial insects to your garden.

Some people say it stands for d**k head. I can type it no matter what my current mood is. ;)

Lol, ok now all of you have me laughing. When I first started seeing it, I would think dick head because my hubby had just weed eated a winter sown plant or used weed killer on it. Either way, he was a DH to me. Then I thought, well, it can't be that because these people are not irritated at their husband. Hmmm.....
