Here are some ideas for plants that would be a good match for this passionate sign.
Rex Begonia
Being a fast-burning fire sign, Leos can benefit from some grounding.
The Sprucerecommends an attention-grabbing Rex Begonia for the lion of the zodiac.

And as far as watering, once a week is enough to keep your Rex Begonia well-nourished and happy.
Be careful not to overwater, as this can cause leaf crinkling and rot.
These brilliantly-colored bulbs are attention-grabbing and gorgeous.

You should expect them to bloom between six and ten weeks after planting.
Before putting them into the pot, soak them for a few hours in lukewarm water.
Cover the bulb three-quarters of the way up the neck with rich soil and pat gently.
