The variety belongs to the crisp lettuce group. The seeds are black. In variety description references, Marbello serves as a standard for the category with very light leaf coloration.
The variety is capable of forming heads, however, under greenhouse conditions, it may show a tendency to form insufficiently dense, open heads under certain temperature and light regimes.
