Also I forgot to add my Euphorbia escalenta that took my 3 attempts to get seeds to germinate and not fall victim to damping off. Out of all the genera of cacti/succulent/ caudiciforms seeds I've attempted to grow Euphorbias seem to be the trickiest and most fragile. On the final attempt I had to sterilize the soil and apply a low dose of fungicide, cause the seeds can't dry out and the soil conditions to achieve that are very favorable to fungi.
Been waiting for it to develop an extensive amount of new tendril heads, but I never seems that interested in putting out much new growth, except this last year when it put of a few new ones. Learned that it responds well to more than adequate watering with regular fertilization during the growing season
