Select the Plant library icon.

Search for plants or look through the categories or collections.

Once you're viewing the plants, you'll see a "Details" button.

Click the Details button.

You can see the available plants of this type, then scroll to read up on all the plant details. Details listed can include the plant type, height and width, compatible hardiness zones, water and sun requirements, plant layer, plant function, and any other pertinent information.

Depending on your location, you may also be able to see local retailers that could carry the plants you're using in the design, with a link that makes it easy to shop their inventory.
