Nepeta Junior Walker plants prefer to be in full to partial sun areas of your garden or landscape. They can also handle part shade in areas that tend to get hot in the summer. We recommend that you provide morning sunshine for your plant to absorb, but once the afternoon comes, your plant should receive light shade for a few hours to avoid any drying of your plant's soil or burning of its foliage and flowers. However, if you live in a cooler growing zone, you will most likely be able to keep your plant in the sunshine for the majority of the day without any worries.
