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?
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.
