Hi, my name is Byron Martin, here atLogee's Greenhouses, and today we're going to be talking about the Desert Rose, andhow to grow them.
The Desert Rose is an Adeniums, and the particular variety thatwe grow is Obesum, and some of its hybrids.
And they're African natives tothe dry, hot regions of Africa.
And, really that is the key in being successful intheir growth.
So, one of the things that Adeniums do is,they form what's called a 'caudex' or this bulb at the base, and that actuallycreates sort of the attractive part of the plant, as well as they have thesebeautiful flowers.
This would be what the species looklike; they're single flowers.
This is one with a pickety edge, but they're oftenpink, like this, and have a bit of a bright edge to them.
And then we have thisone, here, which actually has some yellow in it, as the flower agesmulticolored flowers.
Here's another double with some frosted edges to them.
Sothere's a tremendous amount of color forms in them, and they make great containerplants.
In growing them, that's the key.
Heat and sun, and anything less than that, and the plant actually doesn't do as well, and it can actually suffer.
So,with heat and sun, we also need to remember that they have a, somewhat of adormancy, in the winter time, here, in the northern temperate areas of our world.
And, so, we need to sort-of reduce water, and kind of conserve– they end up dropping leaves, they can actually, actually be deciduous under some stress.
And then they come out in the spring time, and flush into growth andflower during the summertime.
So, in culture, that's what we want: hot, hot, hot.
In our Adenium house, webring it up over 100 many, many days.
We like to see it over 100, andthey thrive at temperatures that are that hot.
And we really don't like to see themgo below 65, although they will take short dips below, we really want to keep them warm.
One of the things that's happened inrecent years with Adeniums, is they've created all these wonderful hybrids, andthen they graft them.
So, cuttings don't usually form a caudex, so if you want tohave this caudex form on them, they generally are either seedlings, which–these are seedlings, right here, with the caudex forming– or you want to have agrafted plant.
And, you can see the graft is formed, right there.
Remember, that in all grafted plants, ifsprouts form below that, you want to rub them off, so that you encourage the topgrowth to be the dominant side to it.
In growing them, summertime comes along; theyneed more water.
And that's the time where they can be given fertilizer.
They're not heavy feeders, but they certainly can have applications of abalanced fertilizer, periodically through the summer– maybe every couple weeks oronce a month, give them some feed so that they havesomething to go on.
We do see insect problems with them on occasion.
One ofthem would be, spider mite can get on to the leaves, so you want to be cautious andwatch over that.
It starts with a little pitting on the leaf, simply some ice-coldwater, taken over to the spritzer– spray them off, or neem oil can control that.
So, thank you for watching today.
There's a little bit of information onhow to grow the Desert Rose, or Adeniums.
Quite easy to grow, if you have the rightconditions, and very rewarding plants, in terms of their flowers.
If you would like more information onour Adeniums, you can go to Logees.
