This is the 1st time I have allowed my gloriosas ever attempt to set seed and the experiment is rather limited in scope. I think they will mature. Glad your's are well Cinta. I've read from more than one reference, Gloriosas are easy to raise from seed. That's the only way one California grower propagates all his stock (and also the reason he can't guarantee a a specific colored cultivar or form).
The results could yields some unique color variations as there's a couple of different cultivers out there (mostly Rothchildiana, superba, some older greenii. and maybe some carsonii). The latter were a new addition this year and the tuber's received seemed to produces a different result than the purple/brown color scheme promised. Had hoped to infuse new greenii into the mix again this year but those tubers sent by provider didn't even raise a sprout. I've been in communication w/ said m o company and they said they'd make good on the errant stock this coming spring.
My usual practice is to remove flowers to provide greater aesthetic appeal and channel energy back into tubers which inevitability yield more tubers every year. I started w/ either two or three small tubers from the gift shop at MOBOT over a dozen years ago, my own stock attained 400 tubers a couple of year's ago. I sold off a bunch, donated 50 or so to a not a raffle raffle, gave loads away, yet still have more than I can realistically use every year.
