Hi 'Solar',
Singularis, aka Fischeri, can get pretty big - like over 2 meters tall. I think it is sometimes commonly called Rhino grass. Plants you see in hobby-size pots never reach those heights, of course. Yours looks like a very nice collector-size plant.

Hmmm another lesson. I didn't know singularis and fischeri were synomyns. On the other hand I wonder if there might not be two distinct variations here (if not species). There seems to be that short tusk like shape and the longer, straighter variety. My references say the longer variety can rach up to one meter in cultivation, but 50 cm is more common. I think the average length of "Rhino Grass" (the short variety) is about 15 cm. The longest spike on my plant is 38 cm.

At the recent C&S show, a person who won a ribbon with her S. singularis explained to me, immature growth versus mature growth and how they differed on this plant. I am still trying to figure this out, reguarding my plants...

I got my singularis at the Dutch van der Wort nursery in Venrtura County, CA. The long spike is almost solid green with no mottling, but three small spikes are all lighter green and mottled. Is that what you meant?

No, the lady said that the two forms of the leaves look like entirely different plants in relation to size of leaves.

I think that is what I meant...

Anyway, she explained that as a plant matures, that leaf changes enough so that you wouldn't believe the immature leaves were part of the same plant.

I'm pretty 'sure' this is what my mystery plant is. It has been sitting there forever like a lump. I was kicking the pot sniping at it, and noticed... could it be?! Well, by golly, I should kick those pots more often! Turned out to be a whole new lead growing out one of the holes in the bottom of the pot. A new leaf!

The old one is old enought to be scarred, marred, and just pretty ugly. It also has quite the curl to it, like you said. The leaf that is pupping is four feet tall, and nearly razor straight.

I see this is an old thread so maybe all concerned have learned this: This sp. like all sans goes through a juvenile form and then an adult form. We typically see it in juvenile form. These will have short mottled (or "banded") curved leaves in pairs. If grown in good light, largish pots and plenty of water and fertilizer during the warm months they will grow into the mature form, which as single tall leaves without banding--a sort of uniform dark green. I have seen wonderful show plants where many juvenile growths filled a pot--I don't know how the grower kept them so small. When grown from leaves or seeds, all sans will display the juvenile forms as they mature into adult plants.

Jon (I once thought there were two forms of this species until I saw "one" grow into the other.)

I have had a pot of this for about 10 years - I just potted it up into larger pots instead of breaking the plant up. It looks sort of like a crown - the little short leaves in the center, and the leaves spiral out while getting longer and longer. The longest leaf now is 30" in a 10" pot. Maybe I'll try to get a picture of it to post; I think it's pretty neat looking.

This looks very much like my Sans cylindrica, which is quite large after about ten years. Do they resemble one another or do you think I was I misinformed as to the variety?
WW, I have also continued to just pot mine up as needed. This year I intended to split it up, but just could not bring myself to take a knife to it:)

Thanks, Elsie
