I thought I might update you on that strange Yucca that was sold to me as Rupicola and now growing a a much smaller one it certainly does not look like Rupicola. Well I repotted that plant getting rid of the peaty soil and replacing with a more loamy type. Not sure what happened but despite being outside but undercover all top growth died but it has pushed up new growth from the roots. I have to say that the new growth looks exactly like my other small Rupicola.
The original plant in peat compost and trunk.

Dead top growth with fresh growth

My new small Rupicola

Hello Andy,

Do you have some photos of the flowers?

Is the leaves serrated? If they are serrated it could be a Yucca reverschonii or just a narrow leafed form of Yucca rupicola.

When Yucca pallida, rupicola and reverschonii have been blooming the rosettes die, and new rosette/rosettes emerge from the rhizomes below. I have noticed that that Yucca pallida and Yucca rupicola is very slow to grow new rosettes, often 2-3 years until anything happens. My largest Yucca rupicola bloomed in 2011 and there are still no new growth, and it's growing inside an unheated greenhouse in perfect conditions.

Juvenile growth of the species in section rupicolae looks very similar to each other when they are young.

Have a nice day

Benny

Andy a beautiful yucca anyway. The last pic is very nice. Any chance it is a hybrid aloifolia x rupicola? That would be interesting. I should put up a new pic of my rupi

Adam.... Your Rupicola looks to me like Pallida.?? Heres mine for comparison

I could be wrong though, these two species seem to be interactive.

Benny... the plant was bought after it had flowered sadly. There is a fine toothed serration on leaf edges Looking at the trunk that plant must have been a few years old. I can only summise that changing the soil and watering it in was the cause of top growth death as my cold low was only -7C and probably less where it was situated.

Andy,

Yucca pallida is actually just form of Yucca rupicola with "blue" leaves, and if you look at the two in bloom, you will see, that the flowers are identical. I still use both names in order to know if it's a green or a blue Yucca rupicola.

Adam,

I don't think, that you had done anything wrong, it's just normal for the rosettes to die off after flowering.

When a Yucca rupicola or a Yucca pallida had been in bloom, it can easy take 2-3 years until the rosettes really die of and then you have to wait again for the new growth to emerge. If you are lucky, your plant will put up more than one new rosette, and maybe the rosettes do not bloom the same year, so it will be a longer period with growth until the last rosette bloom.

Happy Yucca growing to all.

Benny

Hi Andy,

your resprouted Y. rupicola looks like mine seed grown Y. rupicola's from Mesa Garden.

Best regards,

Mario

My observation is that rupicola also has "twisty" leaves and a more "orangish" serrated margin
