Post Yucca rostrata flower dilemma?
My Yucca rostrata is flowering. I've mixed feelings about this, part of me wants to see the flower but a bigger part of me loves the starburst effect I have at the moment. There is also a chance it will branch after flowering which I don't really want either. So the question to leave as is or to chop out the flower? It's going to look crap for a while either way.

If it is going to branch, cutting off the inflorescence now is not going to prevent it.

You're right of course David. Maybe the question should be, will it recover faster if I remove the flower stalk or am I better off leaving it?

Phil I have always cut them off x3 now and it has prevented any of mine from branching.
I would wait until a little more of the inflorecense is showing, than in your picture, then cut as low as possible.
I think with a little luck you could get new growth pushing through the dead hole by the end of the year this is what happened with mine.

Just found the pics this is 5 months after the cut

12 months

18 months

I have never had problem with young Yucca rostrata flowering (I don't care if they branch, but usually they only branch when they are older, say more than 80 cm or 1M of clean trunk), but with Nolina you must cut the flower on young plants, because it can suck all the strength from the plant or make it fall down. I only let Nolina with solid trunk flowering.

I think they are "branching" after they flower, but only making one branch. My understanding is that an inflorescence on Y. rostrata terminates the growing point - it isn't an axillary inflorescence, so it has to make a "branch". Or two, or three, depending on the maturity of the plant.

If someone else knows better, do tell.

Those pictures are a massive help thanks keV.

Thanks for the replies, it seems to be 50/50 on whether to let it flower or chop it off. I'm not precious about flowers and it would seem that they don't always branch on flowering, so I'm going to let it get a bit bigger then chop it out. I have plenty of growing season for it to heal the cut.

The common consensus seems to be 2 years to regrow the crown.

Thanks again.

I think someone already did David, if you see Kevins pics. :wink:

I think you're quite right, the new growth comes from an axillary bud which is usually alone when the plant is less than 1 meter hight.
When the plant has reached maturity it flowers every other year or 2 years later. The crown is a bit less symetric thant it had been before maturity. But the big inflorescences are very showy and last about 3 weeks and branching mature plants are very nice.
Here are some of the Y.rostrata I grow from my own seeds (artificial pollination).

That's a cracking plant, or it will be in two years :shock:

I haven't yet, I can't bring myself to do it!

Sometimes just sometimes flowering can change the shape of a plant

I can't imagine cutting off a Yucca bloom.........especially a rostrata bloom. How are rostratas blooming so small in your climate? Are your Yuccas really rostrata? Do the leaf margins have a fine serrated edge? They seem like a different form from the two I have. Never a bloom on mine since I received them in 2002.
