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 and a half year. Some growers use hormones to promote faster growth.
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 interesting.
We were growing Adenium Obesum Noble Concubine & Adenium Arabicum Brazilian from seeds. Some sprouted in the first few days and 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.
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. Very chubby as well.
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". 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 do this. Because there can be side effects like weaker trees. 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). 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.
