Caper Plant and its Beautiful Flowers

Can you please help me??

I have a caper plant with purple and white flowers. After the flower dies, is the pod attached to a stem the seed??? If it is do I wait till it drys out or pick it while green, and plant. Anyway not sure at all, can you please advise me on how to start a new caper plant, and when, etc, etc. Thank you so much,


Hi Rose,

Here is the link to my page so you can see what they seeds look like on the plant.

Then here are two recommendations on how to germinate the fresh seeds one from Perdue University and the other from The University of California, its quite difficult to grow but well worth a try.

Caper seeds are miniscule and are slow to nurture into transplantable seedlings. Fresh caper seeds germinate readily - but only in low percentages. Dried seeds become dormant and are notably difficult to germinate and therefore require extra measures to grow. Dried seeds should be initially immersed in warm water (40°C or 105°F ) and then let soak for 1 day. Seeds should be wrapped in a moist cloth, placed in a sealed glass jar and kept in the refrigerator for 2 - 3 months. After refrigeration, soak the seeds again in warm water overnight. Plant the seeds about 1 cm deep in a loose well drained soil media. Young caper plants can be grown in a greenhouse (preferable minimum temperature of 10°C or 50°F).

Germination of caper seeds is difficult, but the following methods have resulted in 40 to 75 percent germination. First, heat some water to 110¡F or 115¡F, and put the seeds into the warm water to soak for at least 12 hours, during which time you can allow the water to cool to room temperature. After 12 hours, discard the water, wrap the seeds in a moist towel, place them in a plastic bag, and keep them in the refrigerator for 65 to 70 days. Then take the seeds out of the refrigerator and soak them in warm water (110-115¡F) overnight. Plant the seed about 1/4 to 1/2 inch deep in a soil mix of 50-25-25 parts of UC soil, perlite and sand, respectively (planting mix can be used instead of UC soil mix). Use 6 inch clay pots or deep flats. Water well and keep in a warm area (70-85¡ F.), in partial to full sun. Do not allow the top of soil to crust over. Keep the soil moist. Germination should start within 3 to 4 weeks and may continue for 2 to 3 months. Not all seeds will germinate at the same time.

Good luck and let me know how it goes
