Chamaerops humilis seeds


Neil C

Recommended Posts

I collected some seeds from a friend's stunning Chamaerops humilis and have a few queries. I know that this species requires a male and female plant to produce seed but have also read that a single plant can also have both male and female flowers and produce viable seeds. Will this species only produce viable seeds or can a female plant produce infertile seeds? Secondly I was expecting the inside of a seed to be white but they are a kind of greyish/purple colour. I cut a couple open and they both looked the same, The embryo looked firm and not rotting but not the colour I was expecting. Am I wasting my time trying to germinate these seeds or do these look ok?

Thanks for any replies.

I've never heard of infertile seeds from Euros and most germinate quite easily! x2 on trying the water test for viable seeds.

Seeds look alright and yes indeed occasionally a single Chamaerops can produce seeds, which are fertile anyway. It is not a strictly dioecious palm like Phoenix, it may instead produce on same inflorescence both male and female or hermaphrodite flowers or it can also bloom twice, first time with unisexual flowers of the one sex and second time as described above. However bisexual or flowers of the opposite sex to its dominant sexual charakter are usually very few and thus fruit production is minimal. Even suckers of Chamaerops after being separated from mother plant may change eventually sex.

Being brand new to the sink test I put the fifty or so seeds I collected in a clear plastic bag and filled in up with water. Only about ten sank. I then read that you are supposed to removed the outer flesh and after I did that they all sank so that's good news. I guess there could be another Chamaerops in a nearby garden for pollination or in could be one of those self pollinating plants. Thanks for all your replies and I'll let you know if I get any germination.

Regards Neil
