What is Ice Plant?
Ice plant is a common name for a group of small succulent plants that are native to South Africa. The most common type of ice plant used in landscaping is Delosperma. Ice plant is a low-growing groundcover that forms a dense mat of succulent, fleshy leaves and colorful flowers. The leaves are thick and cylindrical,with wax coating that reduces water loss.The small bowl-shaped flowers of ice plant bloom from spring to fall in shades of pink,purple and white.

The Striking Features of Ice Plant
The distinctive features of ice plant make it a valuable addition to any landscape. Its most striking characteristics are the succulent leaves and colorful flowers.
Ice plant foliage forms dense circular mats that spread out from the center. The mats range in color from silver to bright green depending on the species and cultivar. The foliage covers the ground quickly, providing an attractive groundcover. The leaves are succulent, meaning they are thick and fleshy to store water. This allows ice plant to survive long periods of dry conditions with little watering. The leaf margins are typically toothed or angular,adding textural visual interest.
The main attraction of ice plant are the numerous small bowl-shaped flowers that bloom from spring through fall. The flower colors vary among the many cultivars but commonly include:
During the day, the flowers face upward to absorb http://sunlight.At|sunlight.At night, they fold closed to protect the reproductive parts.
The flowers are followed by marble-sized seed pods that resemble tiny ice balls,giving ice plant its common name.The seed pods persist through winter,providing continuous ornamental value.
In summary, the key striking features of ice plant are:
- Succulent leaves that form dense mats
- Numerous small colorful flowers in shades of pink, purple and white
- Flower shapes that close at night and reopen during the day
- Seed pods that resemble miniature ice balls
These attractive characteristics make ice plant a striking choice for highlighting a landscape bed or filling in bare spots.
Growth Habit and Leaf Structure
Ice plant exhibits a creeping, spreading growth habit that allows it to form dense mats of foliage.Its horizontal stems sprout roots at the nodes to help the plant spread across the ground and fill empty spaces.This mat-forming growth habit enables ice plant to cover vast swaths of ground as a low-maintenance groundcover.
The succulent leaves of ice plant are thick, fleshy and cylindrical in shape.This succulent leaf structure allows the plant to store water for long periods with infrequent watering.The thick leaves also help reduce water loss through transpiration.
The most distinctive leaf characteristics of ice plant are:
Fleshy,succulent texture – The leaves are thick and cylindrical to store water.
Waxy coating – The leaves have a coating of wax that further reduces water loss.
Toothed margins – The edges of the leaves are typically toothed or angular which adds visual interest.
Small size – Ice plant leaves are relatively small, usually less than 2 inches long.
Some key facts about the leaf structure of ice plant:
Ice plant leaves contain a high concentration of water-storing cells called sclerenchyma cells.
The leaves typically turn a darker green color once established to indicate they are photosynthesizing efficiently.
Older lower leaves will turn yellow and die off, a natural part of the growth cycle that helps redistribute nutrients to new growth.
In summary, the creeping mat-forming growth habit and thick succulent leaves with a waxy coating enable ice plant to thrive in hot,dry conditions with minimal care once established. The resulting dense foliage carpets provide an attractive groundcover for highlighting landscape beds and filling in open spaces.
Flower Description and Colors
The diminutive flowers of ice plant may be small in stature but they make up for it in sheer numbers and colorful hues. Ice plant produces abundant clusters of small, bowl-shaped flowers from spring until fall. The size, shape and colors of the flowers vary based on the cultivar but generally adhere to the following description:
Size: The individual flowers measure between 0.25 and 0.5 inches wide.They cluster together in profusion to cover the mats of foliage.
Shape: The flowers have a shallow bowl or rounded shape with 5 petals that are fused at the base.
Colors: Flower colors vary the most among cultivars of ice plant. Common shades include:
Some cultivars feature multicolored or bicolored flowers with white centers and colored edges.
Another notable flower characteristic is that ice plant blossoms close up every evening and reopen the next morning. This behavior protects the reproductive parts from moisture and helps the flowers last longer.
Ice plant flowers are followed by seed pods that resemble miniature ice balls, earning the plant its common name. The tough seed pods persist through winter on the foliage mats,extending the aesthetic value of the plant.
Overall, the small but plentiful bowl-shaped flowers of ice plant, produced in an array of vibrant colors, provide stunning visual interest from spring through fall.The unique habit of closing at night and reopening during the day only adds to the appeal of this versatile succulent groundcover.
Caring for Ice Plant: Tips and Techniques
With a little know-how,ice plant is easy to care for once established in the landscape.These basic tips will help keep your ice plant looking its best:
Provide ample sunlight – Ice plant thrives in full sun with at least 6 hours of direct sunlight per day.Full sun exposure is needed to bring out the plant’s brightest foliage color and maximize flower production.
Allow soil to dry out between waterings- Due to its succulent nature,ice plant is naturally drought tolerant and can survive long periods without water.Water thoroughly whenever the top 1-2 inches of soil is dry to avoid overwatering.
Water infrequently but deeply – When you do water ice plant,do so slowly and thoroughly to saturate the root zone.This may require running your sprinklers for 30-60 minutes once a week during the hottest months.
Fertilize only in spring and summer – Apply a balanced,slow-release fertilizer in early spring and again in late summer. Avoid fertilizing in fall or winter as it can encourage new growth that is susceptible to frost damage.
Cut back old foliage in early spring – Prune away any dead or diseased leaves to make room for new growth and reduce chances of pest and disease issues.Wait until early spring when new growth has started to emerge.
Propagate by stem or leaf cuttings – Ice plant is easily propagated by stem or leaf cuttings. Simply remove 4-6 inch stems,allow to callus,and plant in cactus mix soil.New plantlets will sprout from the nodes.
Control pests with neem oil or insecticidal soap – Common ice plant pests include aphids,mealybugs and spider mites. Spraying the foliage with neem oil or insecticidal soap every 7 to 10 days as needed will typically provide enough control.
In summary,the keys to keeping your ice plant healthy are full sun exposure,infrequent but deep watering,timely pruning and fertilizing,and pest management with organic sprays.But otherwise,this succulent groundcover requires very little maintenance once established,making it an ideal choice for low-stress landscape beds.
