And also, I took this picture at the back of the hotel I stayed. Someone told me it's Yvonne Salvia. Can someone please confirm?

Post #1 pic 1 Is S.farenacea cv"Victoria Blue"
The second plant mixed in looks like Verbena bonariensis
look like a circle of bloom not a spike.

Post 1 pic 2 same as above

Post 2 Is a Salvia splendens does not look as big a
Yvonne's but this bed may have been newly planted
The datura being smaller than S.Black and Blue is not right
either.The Lantana x New Gold should be much bigger as well
Thats my two cents

Hi hybridsage. This garden is in zone 4. That could be the reason why plants are still small.

Thank you so much for the id!!! :D

I agree with Art.

I actually got seeds from S.farenacea cv"Victoria Blue" from that exact plant in the picture above. Hopefully, they'll come true from seeds.
