Adenium growing by seeds

I just received a questions about how long it takes for an adenium seed to germinate. The answer is simple if you have the right growing conditions. First, growing adenium plants by seeds is a low cost method of starting a desert rose plant collection. You can obtain adenium seeds for a few dollars  (packs of 10 of 20) of various flower types. However, you need to remember until the seed bloom you will not know if the plant flower is anything like the parent plant. Only a percentage of adenium seeds will grow into plants with the same flowers of its parents.

Now back to the question. If you have fresh adenium plant seeds and you are growing them in the right condition they will germinate in 5 to 7 days.  yes, I have see some germinate in three days and some 2 weeks.  But 95% will germinate in 5 to 7 days if the seeds are fresh. The majority of the ones that take 10 to 14 to germinate tend to be weaker plants and older seeds.  We have had great success growing adenium seeds under LED lights using tri-band and even some dual band lights. After the seedlings are over 3 months old the adenium plant seedlings are totally removed from the LED and grow under natural light.

We use standard 10×20 trays (the ones with holes/slots all around the sides) and keep the desert rose plants moist by misting them using spray bottles.  Yes, we dome the trays until the adenium seedlings are 1 month old.  If you have any questions concerning growing adenium plants and seeds please let me know. Have a great time growing and collecting adenium, desert rose plants.

  1. I’ve never seen this iNdian fir before and now that I’ve noticed it it’s already 2.5feet high. It’s growing just next to the desert rose’s main trunk and I’m worried might be depriving the adenium of nutrients since the leaves are starting to be few and some are turning yellow. I don’t know where it came from a bird must have dropped a seed or something but yeah that’s it.

    Indian fir = polyalthia longifolia
    Desert rose = adenium obesum
    (thanks to botany class!)

      The dropping of leaves may be due to dormancy of the adenium not the fir. However, anything grown in the same container will use some of the nutrients in the soil. Since the fir is large I would recommend removing it for two reasons: 1) Firs require more moisture in the soil and may be an indication of to much water 2) the optimal growing environments of firs and adenium are complete opposite.

  2. I have 2 huge seed pods from a great DR. I germinated them last year in a damp paper towel roll inside a plastic bag no problem. I was not successful though and I think it was mix and placement of seedlings. What would be the easiest method in getting these guys started. I live in Tampa, fl. Trays? What does “dome” refer to? LED lighting indoors and where can they be found? First timer needing advice. Love the site!

    • You need to germinate in soil not paper towels. I use standard tri or quad band LED growing lights you can find on ebay for $30 to $39. I have purchased the ones sold by a person on ebay who ships from Ft. Lauderdale and they work well. I uses 10 x 20 tray with holes (slots on the sides). Until they are 1 to 1.5 months old I place then under the dome (plastic cover) to keep them slightly moist. I mist the seeds once a day. The trays are outside during the summer under an overhang. Your in Tampa so your climate is just like mine.

  3. So far so good on my seedlings. They have sprouted well and are about 2-3 inches in length with 2-3 broad leaves on top. hey are getting close to hitting plastic cover. Do they need to be trimmed back to create thicker bulb? Right now they are in my garage and in a small greenhouse tray sold at lowes with no LED. Can I just move them outside in indirect light instead of LED?
    thanks again.

    • Your plant is still too young to crop. Do not crop until the plant is 6..7 inches high and the trunk of the adenium 3/4″ of an inch thick otherwise you will shock the adenium seedling to death. I would take the plastic off the seedlings to allow air circulation and to prevent root rot. If you are in a warm climate continue to water the adenium seedlings three…four times a week. Do not let the adeniums seedlings dry out for more than 1 day. I assume you have them in a community starter tray or pot. We do not transplant our seedlings from the community trays until they are at least 3 months old (caudex of approx 1/4″) to increase the survival rate of the adenium seedlings. Definitely give adenium desert rose seedlings more light now! I would recommend 70% sunlight or next too a window that gets direct sunlight at this time. Yes- take them out of the garage or if you do keep them in the garage give them 8 to 10 hours of light from LED or other type of grow lights. This is the growing season and you want them well on their way by the end of summer when they go dormant.

      • Thank you sooo much. I love these plants and this season I got 72 starters from 4 pods from 2 different plants. Outside they go! Your the best!

  4. I like to try to plant by seeds if any you gay able to supply any varities adenium seed.
    wishing kind hearted friend to give some for a try.
    thanks anyway.

    • Good day:
      Small quantities try Ebay for some adenium seeds to start you out. They costs only a few dollars. However, be warned, many of the adenium plant seeds sold on eBay are of poor quality and most will not produce the images as shown. We have tried 7 of the most popular supplies since last year and none of them are truthful about their seed quality. 5 of the 7 sent old seeds and had very poor germination and/or week plants. We are growing at any one time over 2,000 plants from seeds. We have yet to find a supplier from Ebay or Thailand that a persons can trust with any accuracy when it comes to adenium seeds. Basically, once you fined a adenium seed supplier who gives you seeds that germinate and grow well you then have to wait 1.5 to 2 years to see if the flowers are some-what true. Seeds from Hybrids adeniums are not true to their parent plant 40% t0 50% of the time. They are fun to grow by seed but unless you are doing large qty’s you are better off getting proven adenium plants (plants that have flowered).

  5. This valuable blog post, “Adenium growing by
    seeds | Adenium Desert Rose Cacti Blog” illustrates the fact that you really fully understand precisely
    what your writing about! I actually completely am in agreement.

    Many thanks -Thurman

  6. Hello, thank you for the wonderful advice. I use your adenium soil mix recipe for adult adeniums, but I wonder what to use for planting seeds. Would straight coir work for starting seeds? And, at what age do you transplant into the adult soil mix? One more question, you state you dome the trays until one month old, is that domed with no air holes, or are there air holes or gaps for air flow?

    Thank you so much for your help.

    • Hi heather:

      We use a propagation mix that is coir based. When you are growing adenium plants from seeds the water requirement is different than when growing mature desert rose plants. You must keep the seeds moist and then the sprout moist just about all the time for the first month. Moist is the key word. Not soggy. We use 10 x 20 propagation trays with holes for all our seed growing. We spray the adenium seeds twice a day with not chlorinated water and we use LED lights during the winter and 70% shade during the summer for seed growing.

  7. I planted my seeds June 16 2013 my plants are about 1 1/2 inch i want to know if by june 2014 they will bloom i’m desperate to see them with flowers.

    Answer: Adeniums grow by seed will take approximately 3 years to bloom. They will not bloom next year. – sorry

  8. Hello,
    i have recently buy some seeds from ebay and i have planted my seeds in a 4-5 inch cocopeat mixture at 1 inch depth.but before planting i put these seeds in warm water for 4 hrs.please suggest me is this procedure OK or suggest some other method.
    thanks

    • When we plant adenium seeds we do not soak them in water. You need to keep the seeds/seedling moist for the first two months o they get enough water already. The problem with buying seeds is knowing if they are fresh or not. Also, the majority of the seeds do not produce adenium desert rose flowers like the parents no matter what the seller says on eBay or other sites. Currently, we buy seeds from 4 sources (we have tried over 20 different sources including ones on Ebay). Many places we purchased seeds in the past were very poor in quality (low germination rate) and others claim to be a special flower type and they always were normal adeniums. Even the ones we buy now are only 30% to 50% accurate (look similar to their parents). This is the reason we obtain grafted pants from Thailand instead that are 70% to 80% accurate (looks like their image).

  9. My adenium is not germinating.I have planted the seed 20 days ago in a small cup,then I putted it on a heating device(25C) and under a grow light.Please help

    • 20 days is way too long. You may have a bad batch of seeds. Also, did you keep the soil consistently moist? Good adenium seeds germinate in 5..7 days. The seeds must stay moist all the time. Also, the LED’s are they full spectrum, triple wave, quad wave? We use quad wave LED’s for adenium seed germination. Since we are in South Florida we do not use heat pads.

  10. I noticed a thank you for the potting soil mix for your dr Can you share the mix you use I am an avid grower of everything tuberoses plumerias lots of desert roses and my one desert rose has bloomed was planted as a seed from neighbors pod and it bloomed already.Im just really broke since hubby dieed and have to buy certain soils for everthing I do use the coir but my other seeds are still small I had them in my lunia over the winter with the lights and put them outside in april some are getting big but most are still only 4 inches tall any suggestions would be appreciated thank you Kathi from Edgewater fl

    • Adenium seeds are a tricky thing when you purchase them on the open market. we purchase thousands of seeds and depending upon the vendor some are great, some are good and other are just trash. 8 weeks ago we planted 2,000 seeds from three vendors. One vendors seeds germinated about 87%, a second vendors about 70% and the last vendor about 50%. Needless to say I’m not going to use two of the three vendors in the future due to poor adenium plant seed germination. I have another source who is sending me 1,000 seeds and in the past his was the best. we always wont at lease two sources fro adenium seeds. Now once the adenium seed sprout you will get a mix of great growing seeds and then some under performers. The best performing ones we plant are from the vendor who had the best germination rate. The other ones are growing slower and not as thick. All of ours are now under full sunlight but with a clear covering to protect them from direct rain fall.

  11. Hi I’m just going to start on growing adeuims from seed I live in the tropics in Australia do you recommend a place I can buy the seeds from that I would be able to trust they are fresh seeds thankyou deb

    • I buy form Thailand and other sources. The problems with adenium seeds is that most sellers are not truthful about how fresh the seeds are so buy more than you need and expect only about 80% germination adn very few looking like the parent flower.
