I think it's a Rhododendron...

Could be a pittosporum. Could you post a picture of a terminal bud/leaves close up? Also where are you growing this?

It's a Tobira.

I'd like to know the location, too. It does look like Pittosporum tobira, to me.

I agree, used to have one years ago. If you crush a leaf it has a pungent odor.

Was never impressed with the plant. Where ever you plant it, will require constant pruning as it will quickly out grow its space. With the constant pruning it rarely bloomed.

I am growing this in Maryland (zone 7). However, the original cutting was from elsewhere (either Bar Harbor, Main, or San Francisco, California). I will post closeup photos tomorrow. Thanks for your help.

Old Forester, it won't outgrow its space if it's planted in an appropriate location! The flowers are very pretty, with a light, luscious aroma.

Constant, you didn't take the cutting in Maine, unless you saw it in a conservatory or similar.

Did it survive last winter? What was your low?

I got the cutting around November, 2014. I kept it inside (planted in a pot) until May of 2015. In May, I took it out and planted in the ground. In short, this coming winter will be its first winter outside.

If it is a pittosporum I'm guessing it will not survive the winter.

Looks like Pittosporum tobira to me too.

There are a few pitts growing at US National Arboretum, but in a very protected spot and they received significant damage after last winter.

I would not hold out hope that it would be hardy in much of Maryland.

I would keep in a pot. But good job growing it from a cutting!

Constant, I'll also add my agreement that your Pittosporum isn't likely to survive a zone 7 winter. However, it can be grown as a houseplant pretty successfully.

I looked up the Pittosporum plant online, and I now know for sure what I have is Pittosporum, not Rhododendrum. Furthermore, I must have gotton my plants mixed up. When I saw the images of the Pittasporum seeds, I remembered planting similar strange looking seeds. Itis highly likely that my plant did not start out as a cutting. I probably grew it from seed. Too bad, it will not survive our winter here. I will not be able to take it indoors. I have too many plants indoors as it is. Many thanks tı all your assistance.
