Sansiveria (mother-in-laws-tongue) in flower after 35 years?

Question:I have 5 very large Sansiverias given to me, funnily enough by my Mother-in-law. Well she actually gave me one nearly 35 years ago. I have since divided them, and didvided them and divided them, even selling them at car boot sales. Occasionally they have flowered over the years, I currently have one with 6 flowers, the other 4 are doing nothing. My problem is that they are all getting too big for their pots. Some are 5 foot tall. I know they like to be pot bound but it is such a job to divide them and repot them and then, what do you do with them? I feel as though they are taking over my life. If I re-pot them where will I keep them all? If I don,t re-pot them what will happen?

Answers:
get rid of all but one...
they sound gorgeous but plants should be kept for your enjoyment and not feel like a hassle!
you can keep it in same pot may just have to feed them eventually...should actually slow the growth down...
i have a large money plant, maybe 20 years old and haven't repotted that for 7-8 years and it's fine...
