Sorry, it is definitely not Eucalyptus perriniana which has circular leaves that surround the stem completely.

Is your picture a young tree or part of a mature tree? I ask the question because many Eucalypts have different juvenile foliage to that of their mature foliage.

I do see a likeness to Eucalyptus globulus.

I'm no euc expert but it looks like the juvenile foliage of E. cinerea to me.

Curious why you would take it to a home improvement store for ID rather than to a real plant nursery.

Here is a link that might be useful: Eucalyptus cinerea images

Yes: Leaf shape is quite like that of E. cinerea.

thank you for the responses. i thought it was perriniana because my gf had shown me a picture of it online, but there was no name of the plant, so i tried to find something that looked like it, and perriniana was the closest i could find. however, i was still confused, cause i seen others that looked like it and it was starting to get confusing. its growing outside of a closed down circuit city with a bunch of plants. if anybody is sure on what it is, or pretty sure, i would like to buy it, or directed to some place in my area where i could buy it, or online. i went to lowes because somebody that used to work there told me that the garden center might be able to help me identify it because they have books of plants, and they could probably order it if they didnt have it, but that didnt work out. i just started hearing about a nursery from the garden worker yesterday, and have no idea about them, sounds like its the right place to go over lowes. links and pictures would help if u could provide them. i only have that picture because, she said herself " this is the one " so i just went based on my observation, but im no plant expert obviously

It is extremely hard to give a definite id on a Euc with only a few leaves to go on. There are so many species with similar leaves to yours. It really would need a photo of the mature tree, gum nuts, flowers and bark to be absolutely sure.

ok i will try to get some more photos

If you are located in California, E. cinerea is a very likely possibility - it is very commonly grown. A retail nursery or garden center - a place that specializes in plants, not lumber, tools and appliances - should be able to confirm the ID and no doubt carry the plant as well. Eucalyptus cinerea is one of the hardier species of eucs and is even sold regularly at nurseries up here in Washington. There is quite a mature specimen planted in a traffic circle not far from me. If the mature tree has very rough, shaggy bark and strong, pungent, eucalyptus scent from the foliage (used frequently in the cut flower trade), E. cinerea is a good bet.

yes i am in central california, a few hours east of san francisco, in a small city called merced. i have some more pictures, and the foilage itself. the tree is kinda old im guessing, and isn't in great condition as you can see. please let me know if this helps! thx :)

p.s i apologize for the picture rotation, and the closeness of one of em.

You should be able to get a better retail nursery in your area to order Eucalyptus cineria for you if they don't have it in stock. As it gets larger, the foliage will change in shape to a more typical Eucalyptus-type foliage, and this tree can get very big, so it needs room. Two other Eucalyptus species that also have this type of juvenile foliage would include E. perriniana and E. pulverulenta, which are also locally available, or can be ordered.

If you are just interested in having a more manageable sized plant with this type of foliage, (but no characteristic Eucalyptus foliage scent), I'd suggest you look for the perennial Parahebe perfoliata, which does a very good imitation of these Eucalyptus trees, and also flowers.

Judging by the bark on your tree photo, I really don't think it is E. cineria.
