Garden Plant for ID : Kenya : 200611 : AK-2: Taken at Nairobi,Kenya on the 30th of Jan, 2009.
Some Acanthus?

any possibilities for Silybum marianum of Asteraceae?

Earlier discussion on this plant here: efi thread

leaves are too uniform… so, my vote, no…
silybium ok… species do not know…
these are just the basal rosette leaves… do not know what they’ll grow up to be…
