Description
The Blue Mediterranean Fan Palm, which grows in the Atlas Mountains in Morocco up to 1700 m (5600 ft.), offers all the virtues a palm enthusiast from outside the tropics could wish for. It is as robust and adaptable as its regular green relative and happy in a wide range of conditions, tolerating extremes of cold and damp, heat and drought, and full sun and shade. However, its main attraction is the color of its leaves: the upper and lower surfaces of the leaf blade are an intense powdery blue silver (and here we don’t mean the comparatively faint silvery color as seen on the undersides of the leaves of many Chamaerops). It is easily as silvery blue as the best Brahea armata or Bismarckia. Under the laws of botanical nomenclature this palm would actually correctly be called Chamaerops humilis var. argentea, with Chamaerops humilis var. cerifera as a synonym. We have decided to list it as Chamaerops humilis var. cerifera for the time being however, a) because it is by now a well known name in the trade and b) because the name Chamaerops humilis var. argentea has frequently but erroneously been applied to Chamaerops with silvery leaf undersides, not at all connected or comparable to the plant discussed here. We were the first to market and popularize the Blue Mediterranean Fan Palm in the early 1990’s with the help of legendary Morocco nurseryman Sadek Tazi, and our seeds are still collected in the High Atlas Mountains and provide a welcome supplemental income for local folks.

Chamaerops humilis var. cerifera, commonly known as the Blue Mediterranean Fan Palm, is a hardy dwarf palm native to Morocco's Atlas Mountains, prized for its distinctive silvery-blue waxy foliage. This cold-hardy variety germinates best with warm, moist conditions and benefits from either fresh seeds or those that have undergone natural dormancy-breaking. With patience and proper technique, it germinates reliably within 1-4 months, making it suitable for both indoor propagation and outdoor cultivation in temperate climates.

Soaking — 48 hours
Soak seeds in warm water for 24-48 hours. Change water daily. Remove fruit flesh before soaking.

Chemical scarification
Optional: sulfuric acid treatment (15 minutes) can increase germination from 34% to 68%, though dormancy naturally breaks after 10 months of storage at 15°C (89% germination).

Additional notes
Seeds should be lightly covered or slightly inserted into substrate, not buried deeply. Fresh seeds germinate better than stored seeds.
Substrate & Container
Recommended substrate
Peat with perlite, sphagnum moss, or seed compost mixed 50:50 with vermiculite
Recommended container
Transparent plastic container or ziplock bag (sealed or with ventilation holes), minimum 20 cm height for proper root development
Growing Tips
Use fresh seeds for best results. Keep germination container sealed or in a sealed bag to retain moisture and warmth; ventilate every 48 hours to prevent mold. Palm seeds often produce a root before shoots, so monitor closely without disturbing. Once radicle emerges, pot up individually into 9-11 cm pots. Germination may be erratic; seeds can take 1-4 weeks to over 3 months. After germination, provide minimum 18°C for seedlings and acclimate gradually to stronger light. Seeds are non-dormant after storage but can be optionally treated with sulfuric acid for improved germination rates. Avoid waterlogged conditions which may cause seed rot.
