Here is one of the Summer Savory plants, Latin name Satureja hortensis. This one is an annual - which means it won't survive a Winter and needs to be grown again from seed each year.
And here is one of the Winter Savory, Latin name Satureja montana. This one is a perennial, which means that it does not need to be grown each year, but will (hopefully) survive for several years.
|There are actually three plants in that one pot|
The Summer variety is growing much quicker than the other one, which is not surprising since the plants want to flower and set seed all within the one year. Its leaves are softer than those of the Winter variety.
The Winter variety grows very slowly, and my plants are still pretty small. I don't think I'll be cropping them until next year! The leaves are much firmer than those of the Summer variety - more akin to the texture of Rosemary, though perhaps not quite so hard. Maybe more like Hyssop.
I have found that both types have been prone to "sudden death syndrome", in that several of my plants have just died for no apparent reason. I'm not even sure whether the cause of their demise has been to do with bugs or weather conditions or soil or watering or whatever. They just suddenly keeled over. Good job I kept several spares, eh?
