Can you post images of the leaves and flowers, with some common object for scale?

The short calyx one is probably pineapple sage.

There is also one that is Honey Sage that is a variety of S. elegans and is very similar.

Honey Melon Sage has leaves as wide as the standard Pineapple sage, but the length is about half. The scent has additional components that shift the odor from pineapple to a honeydew melon to a degree. It has something of a musky odor in addition to the pineapple.

It is an accession from the Huntington Botanical Garden. The calyx and flower are somewhat smaller than those of the standard.

The second plant is pineapple sage for sure. The first looks like a microphylla to me, but the large leaved ones are not true red, more often fuchsia. Cherry Chief and the deltoid leaved microphylla are that shade of red, also Orange Door and Zaragoza, but the leaf shapes are wrong.

Salvia coccinea has forms with those flowers and leaf shapes. The purple mottling on the lower, older leaves also suggests coccinea. Is it really pineapple scented? Coccinea has a distinct odor, not much like pineapple.

Are your plants growing in a warm to hot shady area?

Yep, the heart-shaped leaf is a puzzle. Definitely both are pineapple scented, though I don't think my sniffer is good enough to discern melon, etc tones. The flower and calyx do look like large microphylla to me, though not the leaves, but nothing like the scent of my other microphyllas. Yes, I have only dappled shade, and it's hot outside Hillsborough.

The heart-leaf one is definitely fruit-scented - checked again. Could it be disjuncta or gesneraeflora? Is it possible that coccinea smells like fruit to me - how would you describe its scent?

Ok, I just had to go smell mine (6:45am and crispy!). My coccinea definitely smells fruity, even like pineapple, and I never even noticed. :)
