I am trying to figure out the correct way to use microdata on a <figure> and <figcaption>

Not sure I am doing it correctly. I have researched this question but can't find anything on using microdata on a figure and figcaption tags when having an h1 and p tags within the figcaption.

      <figure itemscope >
        <img itemprop="image" class="img-fluid rounded " 
           src="https://freedomfieldme.net/images/germinationPoster_02.png" 
            alt="Germination poster of Freedom Field Cannabis Friendly 
               camping and music festival" title="Germination"> 
        <figcaption itemprop="description"><span itemprop="name">
           <h4>Germination!</h4>
              <p>Our first festival of the year. Come and help us start the 
           season off with a bang!</p></span>
        </figcaption>
      </figure>
