Juniperus macrocarpa is a species of juniper, native across the northern Mediterranean region from southwestern Spain east to western Turkey and Cyprus, growing on coastal sand dunes from sea level up to 75 m altitude.
It is a spreading shrub 2–5 m tall, rarely a small tree up to 14 m tall. The leaves are broad lanceolate, produced in whorls of three, green, 12–20 mm long and 2–3 mm broad, with a double white stomatal band split by a green midrib on the inner surface. It is dioecious, with separate male and female plants. The seed cones are berry-like, green ripening in 18 months to orange-red with a variable pink waxy coating; they are spherical, 12–18 mm diameter, and have six fused scales in two whorls, three of the scales with a single seed. The seeds are dispersed when birds eat the cones, digesting the fleshy scales and passing the hard seeds in their droppings. The pollen cones are yellow, 2–3 mm long, and fall soon after shedding their pollen in late winter.

1. Place your juniper seeds in a plastic container of water and leave them to soak for at least 12 hours.
2. Remove the seeds from the water and make a tiny nick in each seed, using a sharp knife. This process is termed scarification and is an important step towards germination.
3. Plant the seeds in trays. Place each seed in a 3/4-inch deep depression in the soil. Cover the seeds with potting soil, but don't compact the ground over them. Keep the soil in the potting trays moist.
4. Place mulch over the seedlings.
5. Cover the mulch with grit to dissuade moss and algae from growing over the potting soil.
6. Keep the seeds at a temperature of 39F (+2-+4C) for 3 months and then transfer them to a room with a temperature of 70F/-+20C. This process is termed stratification and the seeds will begin to germinate at this warmer temperature.
7. Keep the seedlings in a shaded area for the first year of their lives. There will be sporadic germination of these seeds over a two to three-year period. It is important to realize that each individual seed from the same pod has its own degrees of embryo viability. Certain seeds will germinate at once, while others will go into a dormant state. Seeds also have "chemical locks" that degrade to allow germination at different times. These mechanisms afford the tree the best chance at survival, so don't be concerned if not all of your seeds germinate at the same time.
