More on Jeffersonia germination

Just a quick post to show the start of Jeffersonia germination. There were never leftover seeds of Jeffersonia until last year; the slightly larger seed quantity and early cold arrival in late fall of 2022 contributed to this (we know by now that moist packed seeds cannot be shipped when the temperatures fall too much below zero). So, the leftover seeds were kept in moist vermiculite in the fridge.

Pictures taken today: Jeffersonia dubia and Jeffersonia diphylla seeds showing emerging radicles of various sizes.

For those who purchased seeds last year – this should also happen in your pots, or they should be even more advanced. Don’t start scratching the pots! – it takes a while for the shoots to appear from the soil. First thing first – the roots!

It is always interesting to note how long various seeds kept in moist/cold stratification will ‘wait’ in the fridge before starting to germinate. Most species will start to show protruding radicles somewhere in March-April; others even later. Sometimes there is no germination until they are taken out of the fridge and places at warm temperatures.

Until Friday…
