Description

Mediterranean native plant, with a natural distribution in the coastal regions of the whole border of the mediterranean sea west of the canary islands and morocco. Think therefore, that his old habitat was the dry areas of central and western asia.

Grows like a bush between 50 and 60 cm of very ornamental juicy leaves, spreading a profusion of white-pink floral buttons adorned with long and very scented features; which are the edible alcaparras of trade.

The caper plant is known for their culinary properties, wherein their imports floral buttons are preserved in wine, vinegar and salt.

They have been very used in salad, pasta, meat, fish and garnishes to add aroma and spicy flavor to food;

Its strong flavor like a spicy mustard is due to an enzymatic reaction with a mustling oil (methyl glucosinolate) that is released from vegetable tissues when crushed.

That plantinha that is in truth, button floral; it has been transformed in very personality that, that highlights the flavor of cold sauce, like the french, “rémoulade” and “tartare”, and the italian “green salsa”.

Your cultivation is very simple. Grows very very well in stuff or natural; therefore in many countries its plantation is done on industrial scale.

Rare opportunity to acquire alcaparras seeds

Germination Guide

🌍 Mediterranean basin; native range from Atlantic coasts of Canary Islands and Morocco to Black Sea and into Iran
Difficult

Capparis spinosa is a Mediterranean perennial shrub highly valued for edible unopened flower buds (capers) and caper berries. Propagation presents serious challenges due to combined physical and physiological seed dormancy, resulting in naturally low germination rates without proper treatment

Germination
Germination time
Expect germination in

18 – 90 days

Temperature

Min 18°C
Ideal 25°C
Max 25°C
🌡️ Temperature alternation recommended
— Alternating temperature 20-30°C improved germination to 75% when combined with sulfuric acid and GA3; can also germinate at constant 25°C with proper treatment

Seed Pre-treatment
  • 💧

    Soaking — 24 hours
    Soaking in warm water (40°C or 110-115°F) for 12-24 hours recommended; imbibition phase takes approximately 4 days before moisture content stabilizes
  • 🔨

    Chemical scarification
    Sulfuric acid (H2SO4) 98% for 10-40 minutes most effective; mechanical scarification also effective; chemical scarification with H2SO4 increases germination from 23.3% to >82.6%
  • ❄️


    Cold stratification — 65 days at 4°C
  • 📋

    Additional notes
    Seeds have physiological and/or physical dormancy. GA3 (gibberellic acid) 100-400 ppm application critical for high germination rates (87-95%). Fresh seeds germinate more readily than dried/stored seeds. Multiple treatment options: H2SO4 scarification followed by GA3 soaking; cold stratification 65-70 days; or GA3 addition to substrate

Substrate & Container
Recommended substrate
Sandy or rocky well-draining soil; mixture of 50% potting soil, 25% perlite, 25% sand recommended

Recommended container
6-inch clay pots or deep planting trays; well-draining containers


Growing Tips
Fresh seeds germinate much better than dried/stored seeds (90% vs 6% for commercial lots). Multiple dormancy-breaking treatments available. Best approach: warm water soak (110-115°F, 12-24 hours) + 65-70 day cold stratification + second warm water soak + GA3 addition to substrate or seeds. Avoid overwatering seedlings; keep soil lightly moist. Germination slow and erratic even with treatment; sporadic emergence over 3+ months typical. Plant does not flower for 2-3 years minimum
