Origin and Diffusion
Species native to South Africa.
Main features
Flower size
Flower is small, lending elegance to the thriving bloom.
Leaf
The leaf blades are needle-shaped, thick and fleshy.
Flowering period
It flowers from early spring to late summer for a duration of 50 to 70 days, giving colour and brightness to flowerbeds and gardens for a long time.
Leaf color
Solid colour.
Plant height
The height of the plant varies from 0.15 to 0.2 m depending on the creeping habit.
Lifespan
Evergreen perennial succulent plant.
Suggested planting locations
Due to its vigorous growth, colourful and long flowering as well as its drought resistance it is suitable for flowerbeds, rock gardens Suitable as a mound cover, it is also used for green roofs.
Stem/stem
The numerous creeping stems are herbaceous.
Flower
The flower is daisy-shaped, small, with single-coloured petals. It flowers from early spring to late summer, with a flowering period of between 50 and 70 days. It is attractive to bees and butterflies.
Growth
Compact growing variety with a dense and dense end result.
Plant habit
The tapestry habitus creates dense ground covers similar to carpets of foliage dotted with colourful flowers.
branching
The abundant branching allows for highly ornamental results.
Conditions required
pH
Delosperma prefers a soil pH between 5.8 and 6.0.
soil preparation
Before transplanting in mid-spring, carry out light digging, removing weeds, any residues from previous crops and bulky stones; if the soil is too compact and poorly draining, bury sand, then add professional-quality substrate to the surface by approx. 5/10 cm and carefully level out.

Soil/medium
Delosperma prefers a peaty, well-draining soil for best vegetative development and lush flowering.
Maintenance
The easy cultivation and the low level of management effort required add further value.
cultivation tips
Some cultivation tips for best growth and flowering results:
With little light the flowers close Expose the plant to maximum light
Composition
Depending on the type of growth and bearing, combinations can be made with Sedum, Sempervivum and low varieties of Campanula.
Cures and Adversities
planting
We recommend an average density of 15 plants per square metre to ensure proper development of each specimen, thus obtaining a proportionate and compact final composition that best expresses the aesthetic value of the plant with its spring-summer blooms. We suggest placing each seedling on a raised bed with the collar outside the soil surface, taking care not to damage the roots and avoiding completely sinking the root balls, which must be well moistened; finally, water immediately after planting, preferably during the morning hours.
Reproduction/Propagation
Propagation is by apical cuttings and node cuttings.
Irrigation
Use rainwater, alternatively from the aqueduct, by hand watering or with an irrigation system. When transplanting, water frequently with small quantities to prevent water saturation. Afterwards, allow the soil to dry out slightly, avoiding both water stagnation, which compromises the plant's development by encouraging root rot and rotting at the collar, and desiccation with subsequent leaf yellowing. It is advisable not to water the aerial part of the plant during the evening to prevent the spread of phytopathologies.

Following proper establishment in the new planting site, during the spring-summer period, apply a balanced liquid fertiliser specifically for ornamental plants to the soil, to be diluted in the irrigation water in appropriate doses and frequencies as indicated on the relevant information label.
