Lantana seed query
Morning everyone, we've just got back from a short holiday in Spain where I saw what I thought were beautiful orange verbena plants scrambling over walls. Having now googled them I think they were Lantanas. I thought I'd try to propagate some so collected what I thought were seeds but now I'm not sure they are. The 'seeds' were large (4-5mm diameter), black balls attached to the flower part where the petals had been but they're rock hard like a ball-bearing. Does anyone know if I've collected the wrong thing or do they just need a good soak next Spring before planting? Many thanks.
