seeds are from the Eastern Cape blue cycad, a unique and sought-after species among plant enthusiasts. Here’s a summary of key points related to these seeds:
-
: Seeds are pale red to carmine in color and roughly triangular with three flattened surfaces.
-
: The plant itself is known for its striking bluish-gray to silver-blue foliage, which emerges in tightly packed rosettes atop a stout, woody trunk. It is dioecious, meaning plants are either male or female.
-
: Seeds are produced via cones on separate male and female plants. Male cones are typically more tubular and thin, while female cones are thicker and often resemble a pineapple.
-
: Pollination is usually accomplished by insects or beetles, but can also occur through wind or manual intervention.
-
: Collect seeds from mature female cones when they are fully ripe.
-
: Remove seeds from cones, rinse thoroughly, and consider scarifying to improve germination rates1.
-
: Use a well-draining potting mix suitable for succulents or cacti.
-
: Plant seeds shallowly, just covered with soil1.
-
: Provide warm temperatures (around 21-27°C) and bright, indirect light.
-
: Germination can be slow, often taking several months to a year or more.
-
: Seeds typically mature in about six months after cone dehiscence.
-
: Cycad seeds are recalcitrant, meaning they cannot be stored for long periods and should be sown soon after maturity.
-
: Seeds are available for purchase from various nurseries and online retailers, such as Ahead Nursery and Rare Palm Seeds

-
: The leaflets are stiff, sharply pointed, and very spiny, providing a formidable defense mechanism.
-
: Leaflets are spaced in the lower half of the leaf and closer together in the upper half. They are thick, rigid, and obliquely ovate-lanceolate with 1-3 sharply pointed lobes in different planes.
-
: Leaves grow in a crown, radiating outward from the top of the plant, forming a dense, spiky rosette.
-
: There is evidence of variation within the species, including a possible ‘dwarf’ form with smaller stems and leaves.
These unique characteristics make Encephalartos horridus a visually striking and highly sought-after species among plant enthusiasts.
how to cultivate Encephalartos horridus seeds
Cultivating Encephalartos horridus seeds requires careful attention to several factors, including soil composition, moisture, temperature, and light. Here’s a step-by-step guide on how to cultivate these seeds:
1.
-
: Collect seeds from mature female cones when they are fully ripe.
-
: Remove seeds from cones and rinse them thoroughly to remove any remaining flesh or debris.
-
: Some growers recommend scarifying the seeds by nicking the seed coat or soaking them in a diluted bleach solution to improve germination rates.
2.
-
Use a well-draining, sterile potting mix formulated for succulents or cacti. A mix of sandy soil, pumice, and perlite can also be effective for providing proper drainage and aeration.
3.
-
Plant the seeds shallowly, just deep enough to cover them with a thin layer of soil.
4.
-
Keep the soil consistently moist but not waterlogged. Water from the bottom to prevent disturbing the seeds.
5.
-
Provide warm temperatures between 21-27°C (70-80°F) and bright, indirect light for optimal germination.
