Does anyone have any pics of mature or info on either Ravenea sp new or sp giant?

(I have a couple of 5 gal and would like to have an idea of what they are going to grow into before I decide where to plant them out).

Thanks - gmp

Here are two photos. The one that looks like it has been scanned was sent to me by Joseph of Ortanique, who sold germinating seedlings, most of which I have in pots, one in the ground. I don't know the origin of the other phot, but it looks like it might be the same palm and venue.

These are of "Ravenea sp giant" which I beleive they think is Ravenea robustior now.

The plant "Ravenea sp new" is a smaller palm and kind of looks like a Ravenea madagascariensis type. I have never seen a picture of a trunking one. I know Nick here in SoCal has a good sized one close to trunking I think.

Am assuming this would be the R. sp. giant, right?

Any chance you have anything on the R. sp. new?

Thank you very much.

Somehow I overlooked your post before I posted my questions to Mike.

Appreciate all the info.

Here is one from Mardy Darians garden (Mardy called it Ravenen sp. giant). The fronds were twenty feet minimum. Unbelievable plant.

Mike- Just so you know...there is some discussion and belief that Mardys palm and sp Giant, may not be the same palm... BUT it IS GIANT in size!!!!

Zone 10a at best after 2007 AND 2013, on SW facing hill, 1 1/2 miles from coast in Oceanside, CA. 30-98 degrees, and 45-80deg. about 95% of the time.

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

It's difficult to believe that Mardy's plant & the one being sold as sp. "giant" are the same. The sp. giant in every picture I've seen is fairly stocky, much like a Ravenea rivularis. The one at Mardy's was just way different looking; some were refering to it as robustior. It's crown reminded me of a huge R. sambiranensis, just exploding out of the ground.

Something wrong in my first post. I meant Ravenea krociana, not robustior. Sorry. There is actually a palm described in POM under "Ravenea krociana" that is described as being similar to Ravenea krociana but larger and with harder wood. We know for a fact this "sp Giant" palm comes from Mount Vatovavy as that is where the seed came from. So it might be the same palm described in POM?

I have a sp. Giant at my dad's and it is indeed slow and prone to yellow, but it's not too hard to grow. I have maybe given it iron, once and it's in full sun. The palm is growing but it is not a fast palm-at least not for me...

I planted one in July-August 2009. That's the one shown by itself in the photos below, taken today. I planted three more in February and March 2011. The smaller one in the foreground in the pic of two palms is one of them. All of Mandrew's comments apply for me as well (slow, yellowing, and full sun). Orange 5-gal bucket for scale.

Forgot to mention that I had an opportunity to query Dr. John Dransfield about this species once. His response was that the only thing it had in common with R. krociana was that it was BIG. He and fellow researchers considered its possible relation to R. robustior, but were leaning against making that ID. Perhaps we will know more when the revised POM comes out, whenever that will be.

Update on my sp. giant. Yes, this thing is slow! However, what Pete said about them getting past 4 feet and growing faster, seems to be right. I think this palm will do well, in the long run.

Pete, just so you know, there is a big difference between my soil, at my house and my dad's soil. he has much more marl--our form of clay. It hold moisture and nutrients better than sand or rock, which is usually the alternative in South Florida.

Andrew, I have a friend who has been growing this for a couple years longer than I have, & the last two years it has just put on tremendous growth. Last time I saw it about 3 months ago, it was taller than me & really getting girthy. (Picture Matt?) They are very slow to get started as you pointed out, until about waist height & then they really go. Like most Raveneas, water, water. I'll grab a picture of mine tonight I agree that this is not the same palm as krociana. A much, much different looking seedling. Sp. giant is very distinctive with it's black speckles even when bifid. Too bad they lose them.

Bret, look forward to your photos. This palm gets a ton of water and is not far from a hildebrandtii. He has a glauca in the front that gets much less water but seems to be happy with as much. besides the dying majesty palm, Ravenea is very very rare in South Florida--even among palm collectors!

I thought I would provide an update on my sp. giant that i posted a picture of in Dec 2014. Here are two of my larger ones:

I talked a bit more to John Dransfield at the IPS meeting in Madagascar in Oct 2015. Apparently, there are three Ravenea varieties that appear to be closely related - robustior, robustior (coastal form), and sp. giant. The relationships will be defined by DNA work. His opinion was that the three would probably end up as separate species. I took several pics of the coastal form that we observed on Isle St. Marie, and include them below:

As with most everything in my yard, it's tough to get a good picture. The base of this palm is pretty neat; you can still see the heel to the left of the bottle. It's about 4-1/2 foot overall.

Looking good Andrew; much greener looking than the earlier pictures. Mine seems to take longer than most other palms in my yard to get growing when the weather warms up. It looks great, but will only put out 2 fronds this year. Fortunately it looks much bigger with each new frond. You can tell these get to be big palms.
