Dracaena trifasciata

[Mikent]

It looks like my mother-in-law's tongue is getting ready to bloom. First two pictures are from earlier this week. Third picture is showing the development/elongation of the inflorescence. Then I went around to the other side of the plant to water it, and saw a bunch more developing blooms (fourth photo showing two of them). It seems that almost every plant in the clump is sending up a bloom.

If the flowers would be selfing (all of the current plants sprouted from a single leaf), is it likely that any seed-grown plants would have the original gold leaf margins? Or, is that essentially a zero-chance thing (mother leaf looks like a laurentii cultivar, but all the plants sprouting from the leaf lost the margins)? Don't see a bloom coming up from the original leaf (yet).

Probably all former Sansevieria have to be very pot-bound to flower.
I've not flowered trifasciata, but have flowered one clone of parva, cylindrica, Fernwood Mikado and possibly one or two others, and bought a largish desertii in flower.
Parva and Mikado have beautiful and powerful evening scent. Parva grows like a "weed", producing countless runners.

For those unaware, after flowering, that growing point/rosette ceases to grow more leaves as the growing point is what forms the flowering stem.

Leaf cuttings do not come true in the great majority of cultivars, the offsets are usually wild-type - you can find details of the genetics online. I often wonder how many sellers and how many buyers of rooted leaves on EPay actually know that.
Selfed-seed will not neccessarily have the exact same genetics as the parent but I suspect that you will get little or no seed (my guess would be linked to natural polinators, flower shape and copious nectar). Seeds here are rare.
