Many desert rose growers ask: How fast do adenium grow? The answer, my friends, depends on the adenium species & how much food it's taking in.
Generally, if all goes well, a seed-grown desert rose can get bigger, bloom, and produce seed pods within one year and a half. Some growers use hormones to promote faster growth.
Let us show you some fast growing adenium now:
Fast Growing Adenium
The most common variety that many growers grow is Obesum. If you grow them from seeds, they will usually sprout 3-4 days after that.
Some people say that adenium seeds which haven't germinated after 8 days are not viable. From our experience, we have found something rather interesting.
We were growing Adenium Obesum Noble Concubine & Adenium Arabicum Brazilian from seeds. Some sprouted in the first few days while others didn't.
We thought those babies were not going to make it. It was way longer than 7 days, but then they finally took life. We don't remember the exact days. Their body was actually bigger than the "early-sprouters" by the look of it.
So if you like fast growing desert roses, try Adenium Tiny Ding Dong, Obseum & Arabicum. They'll be a great choice for beginning growers. These are super fast growers from our experience. They're very chubby as well.
Adenium also respond very well to generous watering and fertilizing. One time, the adenium master Mark Dimmitt entered his 8-month-old adenium (in a splitting 6 inch / 15cm pot) in a CSSA adenium show. It was disqualified because the judges did not even believe it was less than a year old. He has also grown a form of Adenium Somalense to 8 feet (2.4 m) tall from seed in just two years.
To grow large adenium quickly, you can follow the life cycle of an adenium and fertilize accordingly:
In root-bound condition (the roots grow out to the edge of the pot), even with good feeding and watering, the growth of the adenium may slow down. A good time to get a bigger pot for it is during its active growing season. Meaning, when new leaves are growing out. This is also a good time to feed the plants some nitrogen. This way, they can grow up fast (without exhaustion) following its flow of life.

Since you asked, here are also some slower growing adenium:
Slower Growing Adenium
Adenium Multiflorum grows slower than some others. Some dwarf species like Dorset Horn or Broccoli may not grow up as fast. But they are great for small spaces & bonsai lovers.
There are cases when fast-growing desert roses may grow slower. This is what some growers call "inactive root" or unresponsive plant. Because of this, after the plants are about some months old, they spray root hormone to help it grow faster.
If you're not planning to grow adenium for sale, then it may not be necessary to spray the hormone. Because there can be side effects like a weaker immune system for the plants. It is an option to consider for saving time.
Let's Grow Adenium
That wraps up our brief post on the growth of adenium. So if you're considering this plant for an investment, you can probably get the return in about a year and a half (if all goes favorably).
If you're growing adenium just because you love it, you can just chill and know that the plant will grow pretty fast (not decades like the true "desert" roses). Most cultivated desert roses have been adapted to the home and garden environment.
For some folks who might want faster growth, consider some hormone or fertilizer to boost the growth. Hope this was helpful! Thanks for tuning in & See you next time.
Responses to Readers' Questions
How often do Desert roses flower and can I use yo encourage flowering
--> Thanks for your question. From what I've seen, desert roses can flower multiple times a year in warm/hot weather. With sufficient light, the flowers also last very long on the branches. You could encourage flowering/growth faster by using fertilizer (e.g. organic one like EM1, which can be homemade easily). It's what many use in the nurseries. Some links you may find helpful:
