Hello. I am planting lemon cypress and ceunothus Victoria in one of the focal points in my garden. How far apart from each other should they be planted in order to not look like two separate plants accidentally sharing a bed? I need them to grow into a a mini group, which showcases each of them but in a together kinda way. The photo below, even though it features a plant different than lemon cypress, will give an idea of what I am after. Thank you for your input.
