Euphorbia needs a name

I like this petite Euphorbia. Besides a species name, can you tell me its growth habits?

I think this is a corn cob euphorbia. I can't think of the name...sorry.

I hadn't seen them with leaves before, so I hesitated to say, but now that Dawn has said Corn Cob Euphorbia, that's what I think it is. I checked Frank's site (linked below)~see Euphorbia mammillaris.

Here is a link that might be useful: Euphoprbia mammillaris

YES, thanks Rosemarie! That the name mammillaria. I could not think of it. I have the Variegated kind. You got yourself a nice one Amy. If you'd like Amy, I can give you some of my stems next spring. They root fairly easily.

Amy,
though your plant is a baby yet and with the age its branches may increase in thickness, to me it looks more like E. submammillaris.

Typical branch diameters are
- E. mammillaris: 4 to 6 cm (the variegated form which might in fact be E. fimbriata is slimmer),
- E. submammillaris: 1.5 to 2.5 cm (slimmer again is its "fa. pfersdorfii").

Thanks Frank. I was looking at your website last night, comparing the two species. It's very helpful!

Nice plant Amy.

Whilst we're on the subject, have any of you people heard of 'Euphorbia Pentagona'. I got this little thorny guy a month or two back but can't seem to find anything on how to grow it.

It is a columnar succulent with large thorns and was just labeled 'euphorbia pentagona'. Google gives lots of results but nothing tells me how to care for this plant.

Any help would be greatly appreciated.

Cheers

Kyle

Kyle,
E. pentagona is an easy to care plant. Treat it like the closely related E. enopla, heptagona, mammillaris, ferox etc. In other words: like average cacti but with more warmth in winter.

OK Cheers Frank.

Sorry about the delay, I forgot I posted this. Right, dry dormancy on my windowsill. I'll start fetching it inside the room at night when temps get to low 50's.

Also, do you know how big this guy will grow?

Thanks

Kyle

Kyle,
E. pentagona in habitat builds a compact shrub up to 3 m. Cultivated plants can get even larger. In about ten years your plant will suit better to a larger greenhouse than to a windowsill I think.

Hmmm, making a projection what the content of my greenhouse will look like in about ten years: There will not remain any free space for a bug.
I'll better downsize the plants and take some cuttings!

Wow nine feet, that's huge!

I live in England which isn't exactly hot so it'll probably be more like 20 years. It'll be living in the garden if it gets that big with a shady corner of the room for Winter. It sure would look impressive!

Thanks for the info.

Kyle
