Kalanchoe marnieriana (Marnier's Kalanchoe) is a succulent subshrub, up to 18 inches (45 cm) tall and up to 3 feet (1.2 m) wide, with flat…
If you are growing the plant indoors, select a suitable place where it can receive adequate sunlight as potted kalanchoe bloom well when provided with 8 to 10 hours of sunlight daily. Since in winter the sunlight is less intense, a south-facing window would be preferable. On the other hand, in summer an east/west-facing spot would prevent direct sunlight from damaging the leaves, while also ensuring its normal growth.
Outdoor plants have to be grown in areas where they can receive partial shade during the hottest part of the day as well as get proper shelter from rain.
While indoors, the plant grows and blooms well in normal room temperature, ranging between 65°F (18°C) and 85°F (29°C).
When planted outside, it should not be exposed to temperatures lower than 40°F (4°C) to 45°F (7°C) as it can undergo severe damage or die within a few hours under the influence of extreme cold and frost.
For both indoor and outdoor, the humidity levels have to be maintained low since the plant does not favor misty conditions.
Like any succulent plant, kalanchoe stores water in its leaves for a longer time and hence too much watering is not advisable. Also, wetting the leaves should be avoided to prevent diseases like powdery mildew and leaf spots. In fact, overwatering is one of the primary reasons for these plants’ untimely death.
How often to water the plant
For houseplants, water only when 50% of the soil has dried up or the soil looks dry (they don’t need watering daily) Make sure the water runs out the bottom of the pot to allow the soil to moisten uniformly. If it’s placed on a drainage tray, empty it every time after watering as the plant should not be allowed to sit in the drained water for too long.
Sometimes, when you find the soil too dry, place it in a deep saucer of water for about ten minutes to help the plant receive the required amount of moisture without wetting the leaves.
Outdoor plants should be watered when the top inch of the soil appears dry. Although overwatering should be avoided, leaving the soil too dry can affect the plant growth.
Feed the plant during the growing season with a 20-8-20 high nitrate fertilizer that should be diluted to half or a quarter of the recommended strength every two weeks. If the soil looks dry, water the plant before feeding with the liquid fertilizer to prevent the roots from getting burnt.
Trim off any stems with dead or dying flowers and leaves to facilitate a better bloom. In fact, pruning the plant soon after a new bloom helps in the development of new flower buds in about two to three weeks. Overgrown branches can be simply trimmed off at regular fork intervals.
Wayward branches or stems should be cut off to maintain the shape of the plant. Overgrowth and lack of sunlight make it leggy, resulting in weak and slender stems with low production of flowers.
Dust accumulated on the leaves and flowers can be cleaned by wiping with a cloth or a gentle spray of water regularly. Wipe the leaves with a dry cloth as well as you can after spraying.
How to Know When to Re-pot
The plant needs to be transferred to a new container in spring every 12 to 24 months when it no longer has enough room to grow in the old one. You will know your plant needs re-potting if you spot the roots coming out of the drainage holes, or the flower stems dying soon after blooming.
How to Re-pot
Trim off all dying stems, then hold the main stem near the base and invert the pot to pull out the plant. Trim off any compressed, dry, or insect-damaged root at the bottom of the root ball and clear the old soil from the roots with your hand.
Transfer the plant carefully to a new clean pot, about 2 inches larger than the older container, with proper drainage. Then fill the bottom with a good potting mix (preferably those used for cacti). Make sure the leaves are handled carefully as they are brittle, breaking off easily. Place the plant in the center of the pot so that the crown is below the rim. Add some more potting mix to the top of the container, covering the root ball up to the crown.
Once you are done, water the plant to moisten the soil properly, after which it should be kept dry to allow normal growth and blooming.

Found this in a container with two other different succulents none of them identified. Took it home. Made cuttings for inside and outside. It grows like mad everywhere I've tried it. Now that I have a positive ID I'll be sure to bring it in for winter. Blooms will be a bonus cuz I love it regardless!

A 3” pot planted in March 2016, had grown to about 1’ tall x 2’ wide (in full sun) by January, 2017, when I took 5-6 large cuttings from it to plant next to the mother plant. Started blooming in December 2017.

Grows almost too well here in St. Petersburg, FL, but I haven't been able to get it to bloom. It's readily propogated by cuttings. Just lay a branch on the soil and water frequently (but don't keep soggy) and it'll send out roots. Then, cut it into pieces with each piece having its own roots. Even though mine hasn't flowered, I still like it for the leaves.

Attractive profusely blooming succulent with flat blue-green leaves (that turn pinkish in cooler weather). THis plant is a great spot of red-pink color for any xeriscape garden needing winter color.
