Adenium desert rose growing – how much light is needed

Adeniums, also know as Desert Roses, are one of the easiest succulents to grow in Florida. Florida, with its long summers and very mild winters, provide a great growing environment for Desert Roses. They grow fast and create natural bonsai looking plants.  When planted in the ground adeniums will grow 4…6 feet tall (some taller) with tons of flowers. If you plant in pots you can control the size of the plant from a small windowsill to a larger decorative centerpiece.

The adeniums produce spectacular flowers and grow huge caudexes (massive exposed roots). The caudex gives the plants a natural bonsai look without all the bonsai growing work! In addition they create great centerpieces when in bloom.

You can grow your adenium outside all year long in Southern parts of Florida, Texas, Arizona, New Mexico and California.  If you live in areas that the temperatures drop below 40 degrees then protect your plants.  Adeniums need 5 to 6 hours of full sunlight a day to produce tons of flowers. If you give it more hours of sunlight they will grow faster and larger! They will grow in areas with less light, however, the frequency of flowering and growth of the adenium desert rose plant caudex will suffer.

If you like to have flowers indoors, then wait until they start flowering and bring them indoors to enjoy. That’s what we do with our favorite adenium plants. Optionally, completely grow adeniums indoors using grow lights. AdeniumRose Company grows seeds to seedlings using LED grow lights until they are established enough for outdoors. The seedlings are transfer to the outdoors once they are at least 3 months old and the rainy season is over.  Adeniums can take a lot of water if your soil is correct. But heavy rain (large drops and strong winds) can damage small seedlings so we prefer to keep the adenium desert roses plants under LED lights until its safe for them.

  1. This web site is certainly relatively helpful considering that I’m on the minute producing a web floral site – though I’m only starting up out consequently it is actually rather little, nothing at all such as this web site. Can hyperlink to some in the posts right here because they are really. Many thanks considerably. Zoey Olsen

  2. Hello there, I found your blog via Google at the same time as looking for a related topic, your website came up, it appears great. I’ve bookmarked it in my google bookmarks.

  3. Hi! Our growing season in the Midwest (Chicago) is coming to a close. My desert rose plants did fantastic this season in a hobby greenhouse. I am now getting ready to bring them inside the house because I can not keep them warm enough in the greenhouse in our kind of winter. Would you please recommend specs on LED grow lights? How many watts would I need, etc. I have about a dozen large to extra large plants – all purchased from you! They did ok last year in an east facing window but I think they do even better if I added more light. Thanks in advance.

  4. 3/1/20 Can you please suggest a tabletop type grow light suitable for growing an Adenium plant.
    I am looking for something that does not clip on, and that meets your suggested requirements of full spectrum LED 15 watts. Thank you.

    1. I would love to make a suggestion but we do not use any table top units. We are currently using Spider Farmer sf 4000 LEDs, MARS HYDRO TS 3000W LED and we are trying some VIPARSPECTRA grow lights for the hoyas (Hoyas are partial shade plants).

    2. I had to bring my Desert Rose plants from the colder weather. 11 young ones and 2
      about 2 years old, Southern Ontario. You mentioned the right spectrum. Could you be more specific please ?
      Mine have not bloomed but are growing well. Thank you for your time. 🦋

  5. I just brought home a desert rose. I live in the Midwest (Chicago) so the weather isn’t ideal year round. Should I get a greenhouse in addition to an led grow light?
