I love this graft!

I killed a few on their own roots, then decided even though they aren't quite the same character on a graft, it's still worth having it this way, versus not at all. I've had this one 5 years or so.

Anybody else growing it successfully long term? I mean decades.

Finally got a back-up for the original plant! You can see how much the first plant has grown in just a few months' time. I've only had the new plant for a week now.

I also decided to get a wee tiny plant of the white flowering form, too.

I'm thinking seriously about cutting the spines off the lamerei rootstock to achieve a more homogeneous look. What to you think?

Cutting the spines off shouldn't hurt anything. I totally agree - better to have a grafted plant than none at all! I killed two on their own roots and then gave up.

You can always just bury the graft in pumice...

I was thinking I'd use a judicious placement of rocks to obscure the lamerei, since in nature these always grow in either quartz or other rock outcroppings.

I was careful to find plants that had only an inch of rootstock before the graft so that I could eventually create a natural looking specimen!

I have been looking for brevi on a different rootstock without the spines, but no luck yet. Maybe I'll make some myself on seedlings from my 35-year-old lealii x saundersii plant.

P. brevicaule is always interesting to gaze at. Yours look great and happy but your lealii X saundersii is a killer. I'v never had much luck with grafts of any kind, they always rot at the graft. Maybe it's our bouts with high humidity. The low graft on your plants are really appealing. Never tried a Pachypodium graft maybe it's time.

I can certainly recommend the grafted plants.

You should know that I live in a hot, dry desert with 300 days a year with no rain or clouds and humidity under 15 %. Also, I grow them all on southern exposure outdoors with pretty strong HOT sunshine directly on the plants for six hours in the afternoon! They get dappled sunshine in the a.m.

So this plant is starting blooms now, but the leaves are keeping the flattened look they had last year. I had attributed the flattened look to weak light at the previous grower and thought it would become boat-shaped or cupped in my high light -- but that's not happening!

So I'm thinking maybe this plant is Pachypodium eburneum x brevicaule.

On the other hand, there's variation among all plants and I suppose this could be within the spectrum of the brevicaule concept.

As you can see below, my typical plant from the first post is leafing now and has the expected cupped and boat-shape to leaves.

Glad to see them still alive! Sounds like I should pick up a graft...still love the plant.

Well, my guru for all things pachypodium at Highland Succulents has responded to my direct question to him as follows:

"Both of your grafted plants are absolutely brevicaule. Eburneum is not involved here. You're right that the species does vary somewhat but keep in mind that the first leaves that accompany flowering in all pachypodiums are not typical; almost but not quite. Typical leaves form when the plant actually begins to grow in early summer."

So it will be great to see how these variants mature over the decades.

Default variegated brevicaule

Just getting this one started, but so far it seems just as easy as the others in this thread.

It made leaves of this same variegated character last year, which could have been stress-related variegation or "faux" that later would revert to normal character. However, these images are this year's leaves at this moment a year later, and they seem to be consistent variegation, so I think it's the real deal!!!

Finally got my first bloom on the white form leucoxanthum. I'm still deciding if it's legit.

Here's the same plant from the first post in this thread, to illustrate the size increase in a few years -- still in the same pot. I'm going to minimally repot this year.

Well, my Pachy guru has weighed in on this white form of mine and whether it's the real leucoxanthum:

"Hey Gene - yes you have it. All of the yellow flowered species with white variants are at best ivory with a yellow center. My experience is that the first few flowers of the season are slightly atypical with more yellow. Also as plants mature, flowers are larger and more ivory."

So this clone of mine is legit and is going to get better and better!
