What is this thing and can I eat it - part deux
September 1, 2010 10:14 AM   Subscribe

SO what's this OTHER thing growing on my backyard tree. And more important, will I soon be able to eat it?

Thus far in my backyard I've found plants that grow tangerines, passion fruit, persimmons and the biggest fig tree I have ever seen. I was about to write off the tree outside my bedroom as a slacker there for aesthetic value alone when I saw something starting to grow there:

THEN

I figure it's probably a flower of some kind and ignore it. Then a month passes and now they all look like this:

NOW

They're about the size of a kiwi and they feel on the outside kind of like a lemon. Only I've seen lemon and lime trees and I'm pretty sure that isn't what this is.

So here's the question: What IS growing on this tree, when is it going to be done and when it's finished, will it be edible?

it's a mount royal plum tree, and they are edible, not the easiest tree to grow either...

I don't know what that is, but it's not a mount royal plum. The leaves are entirely wrong and the end of the fruit is very strange and the "flowers" are not plum flowers at all. Don't eat it yet!

That's a pretty funky looking thing at the end of that "plum"...I was curious about what a Mount Royal plum was, and none of the pictures I found had that. Is it just what you get before the flower falls off? I'm not trying to call anyone out; I'm just really, really curious at this point, and would like more information...

It might help us to know where you are.

I'm in California in Los Angeles.

That might by Honeyberry.

It looks like the Blue Joy variety - but not 100%.

any chance we can see a cross section of the fruit?
posted by fozzie33 at 11:14 AM on September 1, 2010


For the record, right now, it looks more green than blue. Though I suppose that could change.

Blue Quandong?

More foliage and a scale reference could help.

Huckleberries?

I found the rose apple, which looks to be the same size and with similar leaves, but the color is totally wrong. Maybe a variety, though?

The funky lobe things reminded me of mangosteen, but it can't be that because the lobes on a mangosteen are on the stem-end of the fruit. Plus mangosteen isn't citrus and the skin you describe has a citrusy texture. I don't know what it is but by the shape of the leaves and the description of the skin I bet it is a citrus of some kind. I looked over several dozen wikipedia articles in the citrus category trying to find something that looked like yours, but no luck. (I did find these weird looking things though!)

I think devinemissk has it! I was totally off on the citrus.

Top Google hit on "fruit that goes from blue to green" came back as Pineapple Guava, which looks rather like your pics and the Wikipedia page says it's about the right size.

You could call up your local agricultural extension office, or even drop by with a sample.

Just note that rose apple and pineapple guava are both in the myrtle family and a lot of what I saw online that looked promising was also in the myrtle family...so chances are, this is some variety of myrtle. (Of course, there are a lot of myrtles out there, but that can help narrow it down.)

I'm with galadriel, I think you have some variety of feijoa aka pineapple guava.
posted by bgrebs at 12:11 PM on September 1, 2010


I was going to say Pinteapple Guava, too, but the leaves look wrong, and those were really blue fruit in their earlier stages.

I think it's related, somewhere in the Syzygium genus, along with guavas, rose apples, and others.

Sorry, but I doubt it's a pineapple guava (feijoa as I knew them). I had one once and this doesn't look like anything I ever saw on mine. What were the flowers like? The feijoa flower as I remember it is pinkish-white, rather like a fuchsia flower.

If you go by the extension office, be sure to take some leaves/foliage also.

The flowers on the fejoia don't look anything like the flower OP posted.
posted by watercarrier at 12:37 PM on September 1, 2010


I also think Syzigium, possibly plum satinash, Syzygium cryptophlebium. Or malabar plum, S. cumini.

Just a thought: Plants are classified by their flowers: A picture of a flower, if there are still any available, would be very useful.

The feijoa flower as I remember it is pinkish-white, rather like a fuchsia flower.

Just for clarity's sake, it's not the flower color that matters, it's the parts. Position of the ovary, number of stamens, pistils, and ovarian chambers, and type and number of flower parts present. I'm guessing most of the people here saying Feijoa or Syzigium are doing so because of the four persistent sepals on the end of the ovary that is shown in the picture. They are both members of the Myrtaceae family, whose flowers tend to have numerous stamens and visible sepals on the fruit.

if they are red, orange, or yellow...i used to call they cherry guava and they are great. had one in california and they grow all over in hawaii. eat 'em and be happy.

Okay it REALLY looks like that rose apple pic.
posted by rileyray3000 at 8:29 AM on September 2, 2010


Seconding rose apple, as they can be green, not just yellow when ripe and the foliage looks right. They have a great crisp texture, but I hate all things rosewater-flavored, so I give them a 'meh'.
