Trans-Pecos peyote with fruit – it’s an echinata!

It’s that time of year again. Most of my peyote plants have flowered freely all through summer and now the eagerly awaited results, the fruits, are appearing (many of my plants are still flowering so I’m hoping for a good seed harvest this year ;-)

Fortunately the majority of my coldhouse grown Trans-Pecos peyote plants (Lophophora williamsii var. echinata) survived this winter’s harsh frost (contrary to my “regular” Lophophora williamsii growing in the same unheated greenhouse – most of these plants succumbed to the frost).

The first fruit appeared on one of the surviving Trans-Pecos peyote plants only a few days ago. I’m looking forward to growing these seeds as the parent has a proven record of frost hardiness and I expect this trait to be inherited by its offspring (I’m using the singular “parent” as I assume this fruit to be the result of selfing; it only contained two seeds). Hopefully many of the cold grown Lophophora williamsii var. echinata plants will set fruit during the next couple of months ;-)

I’ve been made aware that my use of the echinata epithet is not entirely clear. To clarify, I’m using it in the sense of Del Weniger – others, e.g. Backeberg, are incorrectly (IMHO) using echinata to describe what seems to be diffusa.

In his book Cacti of the Southwest Del Weniger describes L. williamsii var. echinata as being a larger, tougher form of the species, having heavier and larger stems and not clustering to any marked degree (possibly with a higher mescaline content also). Furthermore the echinata variety is described as being much more tolerant to extreme temperatures, both hot and cold (Weniger writes: “This form is found growing on dry, exposed hillsides of the Big Bend where the lower Rio Grande Valley form would be burned to a crisp. It can also survive the much more severe cold of the Big Bend. I have several times had the smaller form from south Texas freeze in San Antonio, while this form growing in the same bed showed no ill effects”). The range of the echinata variety is given as “Northern Mexico, extending from Chihuahua and Coahuila into the Texas Big Bend in lower Brewster County”.

I have to admit that I find it rather difficult to clearly distinguish the echinata and regular williamsii forms based on morphology alone, especially young cultivated plants. So I rely heavily on locality information when buying seeds and to play it safe I prefer material originating from the Trans-Pecos region of Texas, the northernmost extreme of the Lophophora genus’ range.

But as my horrible experience this winter showed the echinata variety (in this case Lophophora williamsii var. echinata JJH 8608293; Pecos River area, Val Verde County, Texas) definitely seems to be more frost hardy than the regular williamsii variety.

  1. I have a small peyote and this week it had its first flower. My apartment is not very sunny so I'm keeping it under cfl lights. I was wondering how long does a flower normally last and after the flower dies how long does it take for the fruit to form?

  2. The individual flowers only last a couple of days but typically mature plants flower many times during the growing season.

    Regarding the formation of fruits, I made a controlled experiment with one of my grafted plants to examine how soon you can expect a fruit after your peyote plant has flowered and found that fruits appeared 7-8 weeks after pollination. A more general answer would be that peyote flowers pollinated in spring/early summer will fruit in late summer/early autumn, while flowers pollinated in the late summer will form fruits early the following spring.

    I usually pollinate my plants using a q-tip.
