Lav. 1970 action

Post Number:#1  Postby Azuleja » Sat Nov 18, 2017 10:38 am

At first I wasn't sure what was going on here, but now it's clear that I may be getting a bloom spike. Seems weird that it's growing as the weather is getting cold, so I hope it doesn't change its mind.

Sans (at least most of 'em) are winter bloomers. If anything, your guy strikes me as a little early. But good for you, maybe the cycle will complete before first freeze kills the stalk.

The timing does seem a little off to me.
One of my S. halli bloomed fully in Sept. 2016.
S. suffruticosa and S. 'Boncel' in April 2017.
I failed to get proper pics, but S. fransissi bloomed circa Aug. 2016. I have a pic from end of Aug 2016 with nothing but a dried bloom stalk left over, so it was apparently blooming in the month or two prior.
Nothing so far for me during our winter months, but perhaps I'll run into that too in the future.

Notable as well - "winter" in Africa is circa June, and much warmer than our winters, and it is especially noteworthy that using Kenya as a proxy, and using Nairobi for stats easily available, the short days of winter (June 21 Solstice) are 12:03 hours short, and the long days of summer (Dec 21 Solstice) are 12:12 hours long. In other words, that close to the equator (89 miles away http://dateandtime.info/distanceequator.php?id=184745), days and nights are about the same year round, implying tropical climate.

As far as the conditions mine are grown in - natural daylight hours with some augmentation early and late using LED making the most difference during our short days of winter, but winter lows are mitigated in a greenhouse kit with a heater that prevents anything near frost or freezing. We had 32 degrees as of 7AM today, and stepping into the greenhouse kit, it was quite comfortable - not hot, but far from the cold right outside.

Kenya (Nairobi) lows year round - 52-59F highs 72-82F . The driest months are circa their winter - June-Sept.

It would be hard to argue that the blooming trigger is a change in photoperiod If daylight hours don't change much in habitat. Same for temps which are also fairly constant. The only other variable is rainfall as a possible trigger, and if these plants do bloom in "winter" in habitat, then perhaps the drier months are the trigger? Sheer speculation on my part which is not supported by my blooming events so far - but then the daylight hours here fluctuate a great deal between summer and winter, as do temps. I keep mine relatively dry in winter (our real winter circa December), and no blooms for me so far. Blooms so far April-Aug, when they are well watered. Based on my own observations so far growing in conditions far different from habitat conditions, I have no clear idea what triggers blooming for these plants.

Perhaps Marlon, who grows in South American tropical climate can provide some enlightening information regarding bloom times in conditions that should be roughly the same as African habitat.

Edit
OH! I forgot to say Congrats Azul on the blooming. Would love to see updates of the flowering process.

I would guess a lot of tropical Sans don't experience winter at all, at least not winter as we experience it.

I've only had trifasciata and cylindrica bloom, and both do their things in Dec-Jan.

BTW, blooms are not especially impressive to look at, but they are wonderfully fragrant -- like orange blossom fragrant.

I'll definitely update as it grows. Do you know if it will resume growth from the same point when it's done?

Yes, I agree. Summer and Winter have little of the meaning there in habitat compared to what we know and experience in the northern hemisphere - which is why I think it's important when folks mention for various plants "summer/winter grower" etc. to fully understand and appreciate the actual conditions in habitat. It appears the main seasonal difference there is the amount of rainfall, and that's about it. 12 hours days and nights year long aren't going to distinguish the season, nor rather constant temperatures either.

S. trifasciata has never had much appeal to me. One species, and a million variations. OK, maybe not a million. ::wink:: Anyway, the 2 or 3 of those I have have never bloomed to date.

The most interesting blooms I saw were the S. halli which bloomed. It was a very interesting cluster that seemed to grow right out of the soil near the base of the plant, and not out of the plant itself as we are most accustomed to seeing. I'd say that was impressive in itself, but other bloomers were rather bland looking white and small flowers.
Here's the S. Boncel. Sure, it was nice to see it bloom, but not super impressive. I think the main interest in seeing the bloom formation is in how it relates to the identification of the species.

It's my feeling now that Marlon educated us on his plants' year-round growth in tropical growing conditions - that growth is a function of year long amenable temperatures and constant lighting. We, growing in northern climes have introduced a new variable with cold temps, and short vs long days compared to habitat... so without modifications (lights for winter increasing the photoperiod and heat in the winter to guard against cold), growth does appear to be affected. Even though I do mitigate the effects of winter, it's definitely not the same as the favorable conditions they receive spring through fall - so growth does seem to slow down. I would guess that the more and better one compensates for cold and shorter days, the more these plants likely exhibit constant and uninterrupted growth.

When my cylindricas bloom, that's the end of it -- no more leaves for you, but that's what cylindrica does whether it blooms or not. Three or four leaves, then onto the next one.

Lucky you! Things should move very quickly from here.

Thank you, I realize it's a bit dehydrated looking but I've been afraid to overwater it in cool weather.

Very cool. Dehydrated or not, it's still a fantastic looking sans!

Thanks, Steph! Our nighttime temps have been in the 30's and my sunroom has been getting down around 50. We're supposed to hit 32 tonight.
