Seeds for ice plants can be sown early indoors and moved outside after a frost.
Indoor Seed Sowing
- 4-6 weeks before to the last frost, sow.
- Seeds require sunshine to germinate, so press them firmly into the soil without covering. As soil, use a seed-starting mix.
- Up to germination, keep moist.
- In 15 to 20 days, seedlings appear.
- As soon as seedlings appear, give them lots of light on a sunny windowsill or grow them 3–4 inches beneath 16–hour-per-day fluorescent plant lights that are off for eight hours at night. As the plants get taller, turn up the lights. Because they will become too hot, incandescent bulbs will not function in this process. Do not leave lights on continuously for 24 hours; most plants need a time of darkness to flourish.
- Seedlings don’t require a lot of fertilizer; feed them when they are 3–4 weeks old with a starter solution (half the strength of an indoor plant food), as directed by the manufacturer.
- Seedling plants must be “hardened off” before being planted in the garden. By relocating young plants to a protected area outside for a week, you can acclimate them to outside circumstances. At first, be sure to shield them from the wind and the light. If frost is expected at night, cover or bring pots inside; then, in the morning, reintroduce them to the outdoors. The plant’s cell structure is toughened during the hardening off process, which also lessens transplant shock and scorching.
Introducing Plants to the Garden:
- Choose a position with full sun and sandy, well-drained soil after all threat of frost has passed.
- Turn the dirt under to a depth of 6 to 12 inches, remove any debris, and lightly rake the soil as level as you can to prepare the bed.
- To lessen transplant shock, plant during gloomy weather or in the late afternoon.
- 18 plants apart.
- To save water and prevent weeds, thoroughly moisten the soil and sprinkle a thin layer of mulch (no thicker than two inches) on top.
How to Grow
- Keep weeds under control while the plants are growing. In order to suppress weeds, either cultivate frequently or apply a mulch to stop their germination. Weeds compete with plants for water, space, and nutrients.
- Mulches also support stable soil temperatures and moisture retention. Shredded leaves used as an organic mulch for annual plants give the bed a more natural appearance and, as they decompose over time, enrich the soil. Mulches should never be placed on a plant’s stems to avoid potential decay.
- Observe for illnesses and pests. For advice on pest management measures that are suitable for your area, contact your cooperative extension service.
Is it simple to produce ice plants?
Ice plants (Delosperma) are a simple-to-grow and prolific blooming ground cover alternative if you’re seeking for a colorful solution to fill up space in the yard. These heat-loving perennials, which are native to South Africa, may be the center of attention in the landscape, but they actually do best when given a little bit of a break.
They are attractive additions to rock gardens, borders, pots, and ground covers due to their quick growth and constant bursts of joyful, daisy-like blooms. These floral carpets are resistant to deer and attract butterflies, bees, and other helpful pollinators.
Enjoy heaps of stunning color year after year by following our advice on how to grow and care for ice plant ground cover!
How long does it take an ice plant to mature?
When cultivating an Aizoaceae plant inside, temperature control is less of a concern. When the temperature falls below 2 degrees Celsius, animals in the wild cannot live.
Your plant will thrive if you maintain a temperature range of 10 to 21 degrees Celsius in your home.
HUMIDITY
In general, succulents don’t like places with a lot of humidity. When the air is overly moist, root rot and other fungal issues can arise. A humidifier or routine misting are certainly needed for some of your indoor plants.
Avoid applying these strategies to your ice plant. Also, stay away from putting them in a location like the bathroom that has a lot of natural humidity.
FERTILIZER
The Ice Plant’s blossoms come in a variety of hues, including pink, orange, and yellow. Unless the soil is rich in nutrients, these people might require additional assistance from a fertilizer. To encourage healthy growth, a balanced fertilizer should only be applied in the spring. They don’t require it beyond that, plain and simple!
PROPAGATION
Ice plants can be multiplied in a number of ways, including cuttings, division, and seed germination. One of the simpler ways to create a clone is through stem cuttings. For best outcomes, this procedure should be carried out in the early spring. Uncertain about how to proceed? Not to worry! Later, we’ll have the steps.
GROWTH
The Aizoaceae family doesn’t really get very big. Ice plants only grow to a height of six inches and a width of four feet, being more like a shrub. They can actually reach this mature state in less a month if all of their needs are addressed. Ice plant species that can spread out and grow lanky can be controlled by routine trimming.
POTTING
The Ice Plant doesn’t require repotting due of its hardiness. The roots remain quite tiny and don’t become overcrowded. If the roots of your Aizoaceae become too damp, for example, you might have to move them to another container. For ice plants, saturation is a big issue. You should repot the plant if it can’t dry up soon in order to prevent fungus growth and root rot.
How can ice plants produce seeds?
Ice plant seeds should be directly sown in the soil in the late fall since they require sunshine to germinate. Keep the soil moist until germination, which typically occurs within 14–21 days, by mixing the seeds with moist sand and storing them in the refrigerator for 30–60 days prior to planting. This is especially important for spring planting. This seed can also be started indoors six to eight weeks prior to planting in the spring; after the last chance of frost, move the seedlings outside.
Growing: Provide seedlings with water until they are well-established, but avoid overwatering. For dry slopes, rock gardens, or other dry and sunny settings, mature plants are a great choice because they can withstand drought well. If the growing conditions are right, these plants may reproduce themselves.
Harvesting: Select stems with freshly opened flowers for use as cut flowers. Remove any foliage that will be below the water’s surface and submerge it right away.
Saving Seeds: Seed pods will form after the blooms have faded. Harvest the pods as soon as they are dry and have turned a reddish brown tint. To get the seeds out, crack open the pods. Ice plant seeds should be kept in a cool, dry area.
Can an ice plant be grown indoors?
I prefer plants that serve two purposes, ones that can be used in both outdoor and inside landscaping. A plant that precisely fits that description was given to me by a friend who enjoys gardening last year.
Good day, time traveler! Information in this article may no longer be accurate as it was published on 9/11/2017, which is 1709 days ago.
The plant she gave me is called Aptenia cordifolia ‘Variegata’ and is also known as variegated ice plant or heartleaf ice plant. She gave me the plant at the end of the growing season, and I enjoyed it in my sunroom during the winter. This summer, I moved it outside, where it put on a lovely display.
Some of you may be familiar with the Delosperma, or ice plant, which we cultivate as an annual flower. The plant I was given is not the same as this one.
The annual ice plant, which is cultivated from seeds, has green leaves and stunning purple, yellow, white, pink, or orange blooms. The term “ice plant” comes from how the green leaves shimmer in the sun.
The spherical green leaves’ surfaces are covered in tiny calcium crystals that reflect and retract light, giving them an ice-crystal-like sheen. To contrast with the more vivid petal color, the petite, single flowers frequently have white centers that are elegantly fringed.
Due to its extreme drought tolerance, ice plants make excellent plants for hot, dry areas in the garden. In fact, overwatering an ice plant will frequently cause it to rot and die. It can be planted in window boxes and pots, where its trailing growth habit will cause it to spill over the edge of containers, or as a ground cover.
Due to their low growth rate and ability to crawl across the soil’s surface, these plants, which only reach heights of 10-15 cm, look attractive at the front of a border. When the sun is shining, the brightly colored blooms will draw a lot of attention.
Although it is a separate genus, variegated ice plant is a member of the same plant family as common ice plant. It is a creeping succulent with three-cm-long, cream-and-green variegated leaves.
Its foliage is what makes it a good indoor plant; unless it is placed in front of a sunny south window, where it might produce some flower in late spring, it is unlikely to blossom indoors. I plant it indoors because of the lovely foliage.
The leaves don’t shimmer like those of Aptenia cordifolia; they are smooth. Individual leaves don’t lay flat; instead, they usually have a small cup-like shape. The leaves are juicy and meaty.
The trailing growth tendency of the variegated ice plant will eventually cause it to flow over the side of its container and cascade downward. If you use careful pinching, the stems will branch and a fuller plant will result.
Despite having magenta, pink, and white types, the specimen I have blooms bright red outdoors in the summer. This is one plant that dislikes being chilled, so I wait to put it outside in the spring until the nighttime lows are consistently over 10 C.
When it’s in the sunroom during the winter, I put it in a bright spot that’s far enough from the door and windows from keep it from becoming cold. The plant is typically kept in a container that is suspended from the ceiling, which further prevents the plant from being chilled because heat naturally rises in a room.
Since ice plants, particularly variegated ice plants, are tropical plants with South African origins, they are not at all cold-hardy. Frost will destroy annual forms, and they won’t survive an outdoor winter even though they will self-seed. Variegated ice plants cannot endure our harsh winters outside.
Variegated ice plants require only minimal watering, like the majority of succulents. Before adding more water, the soil needs to almost entirely dry out. The soil can be soaked and then left to drain outdoors in a container with good drainage, but indoors during the winter, this would be too much water.
Overwatering will cause the plant’s leaves to become limp, turn yellow, and eventually die. The plant should only receive very little watering over the winter, just enough to keep it alive.
The rapid growth tendency of variegated ice plants is prized; by the end of the winter, a pot of slips will grow into a nice-sized plant. In slightly moistened soilless mix, cuttings take root readily, and numerous of them, each approximately 6 cm long, will fill a good, full pot.
Variegated ice plant would work well as a trailer in a mixed container, even if I have not tried using it in this manner. To avoid being overpowered by its neighbors, it would need to be put directly at the front of the container.
I prefer to admire this pretty plant in its own pot as a specimen plant. With its appealing cream and green leaves and (in the summer) its exquisite red blossoms, it competes both inside and in the outdoor garden.
Does ice plant require shade or sunlight?
Ice plant quickly creates a low carpet of succulent foliage that adds texture and interest even when these sun-loving perennials are not in bloom, making them ideal for sunny slopes or rock gardens. Once established, there are few plants that are simpler to manage because they don’t need any specific maintenance. The term “ice plant” refers to the tiny, shimmering spots that appear to be ice crystals on the leaf. Ice plant, which may reach a height of 6 to 8 inches, blooms all summer long with vivid daisy-like flowers in purple, pink, or yellow. It resists drought and deer. Zones 5-9.

Ice Plant Growing Instructions
Ice plants need a bright location with at least 6 to 8 hours of daily direct sunlight. Although it can survive little shade, it doesn’t blossom as much.
Put it in a soil that drains nicely. The ice plant despises clay and poorly draining soils; if it is planted in an area where there is persistent standing water, it frequently perishes. Ice plants should be planted on a hillside or slope where the soil will swiftly drain after a storm for the greatest results. It works well on raised beds and mounds as well.
Pruning the ice plant is not a concern. This low-maintenance groundcover doesn’t require fertilizing in the majority of soil types, although you can if you’d like.
Add these types to your Ice Plant to complete it:
Agave A few Agaves scattered around the bed will provide an Ice Plant border drama and interest.
Island poppies Iceland Poppy can be used to add splashes of vibrant spring color to your Ice Plant.
Together, Sedum Sedums and Ice Plant make a wonderful combo because they are both equally tolerant of drought and have beautiful leaves.
