So I had to pull up some huge rosemary plants in the front yard to have some plumbing work done. I noticed that the rosemary I’ve bought to replace it has completely different leaves. The old plant was more like an evergreen with oily needle-like leaves. The new plant has soft flat leaves but still smells like rosemary.
Are these two plants actually related? Are they both edible? The “evergreen” One was fairly hearty and grew quickly. Will the other variety act the same?
There are different types of rosemary, and as the other poster said there are differences within one sub-species that can make identification a hazy academic pursuit.
If you bought rosemary that was labeled as such, you know you have rosemary. The plant you took out, consider it a type of rosemary and leave it at that. If you like the rosemary you had better, you can clone it with a cutting and grow it anew.
In addition to the fact that there are different varieties as people have noted, plants change as they age. A nice, new seedling will sometimes be softer, and gradually get more woody as time goes on.
Culinary herbs like rosemary have tons of varieties. This is likely the reason but they should both be fine to eat.
The number of different basil varieties / cultivars in Culinary Basil (Ocimum basilicum) is mind blowing. That isn't even counting the different species of basil such as holy basil (Ocimum tenuiflorum).
There are quite a few (at least 20, probably more) varieties of rosemary. It's a wonderful herb, and I should try growing it again. I keep killing mine, so maybe I should give up. Nah!
How do you keep killing it? Mine kinda just hangs out in a huge pot outside and is generally chill. I let it dry out completely before watering it again, though, since this is the advice i was given online, but otherwise it kinda takes care of itself
Lots of plants have different varieties of the same species. It's impossible to say without knowing which variety. It should be stated and described on the tag from the grower.
