No 1 looks like Salvia Spathacea,No 2 looks like it maybe salvia Roemeriana, Not sure what 3 is:)

Sarah, #2 looks like salvia regla to me and #3 like salvia caudata 'el cielo blue'. I think Annette guessed #1.
Salvia regla is deciduous.

# 1 is Salvia spathacea

# 2 is Salvia regla, probably the Jame, Coahuila form

# 3 is Salvia caudata, formerly known only as El Cielo or Blue Sky sage

I also agree:

1........spathacea

2........regla (though foliage resembles roemariana) How tall is the plant?

3. 'El Cielo Blue'...also known in the UK as 'Blue Sky' this has tentatively been identified as Salvia caudata, a very beautiful Salvia, whatever it is!

Robin.

Thanks annette,Helena Richard and Robin. Where is caudata and regla from? Thanks again The regla is very small,

The Salvia caudata was collected by Yucca-Do in the El Cielo Biosphere in southern Tamaulipas state in Mexico.

I collected the seed of the Salvia regla from a side road in northern Coahuila in the vicinity of Jame on a collecting trip with the Yucca-Do folks. After growing it out, I distributed it to botanical gardens and nurseries like Plant Delights.

Thanks Richard It's a real beauty! I wonder if it's hardy no matter I will dig it up like I did with the andean sage thanks again.
