Thursday Seedex with Asteraceae

I’m late with preparing the seedex donations; just sent a small one to the SCRG and since the local mail doesn’t take long, I’ll pack a few more for ORG & HP Society this weekend.

It’s not easy to decide what to give; I always start to think what would be more attractive from what I have surplus, then some need more cleaning than others, and so on…Speaking of cleaning, nothing is more disappointing than receiving the wonderful little packets only to find inside ‘not so good seeds’, or just parts of them (it happened a few times).

Special attention is needed to all species in Fam. Asteraceae because by as a rule some of the seeds are always empty and it is not always easy to see which ones with the naked eye; a strong hand lens is necessary.

For example, let’s look at Anthemis carpatica ssp. pyrethriformis I just prepared for ORGS & HP. This subspecies, endemic to Eastern Carpathian Mts., while bearing the same large flowers is smaller in size than the regular A. carpatica.
It is super easy to grow from seeds (warm germinator) and is a good plant for any rockery (attention when planting the grown seedlings in the garden – they need very good drainage). The seedlings shown are from a previous seed collection I did few years ago.

and the non viable ‘seeds’

Anthemis carpatica ssp. pyrethriformis – non-viable seeds; when shown already separated, it seems easy to distinguish them but actually I had to use a x 40 hand lens to do it!

Another Asteraceae donated to both SRGC and ORG & HP – Jurinea mollis seeds are shown in the featured image.

Two years in a row, instead of seeds I found in the seedex packets just the pappus of a dwarf Jurinea species (from AGS Seedex).
This is how Jurinea seeds look like, with variations depending on the species and the moment when the seeds were collected (the pappus can be reduced in size or it may have fallen out).
