How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Begonia rex 'Fireworks'
Begonia rex 'Fireworks' is a larger Rex Begonia with pink-edged leaves, a grey-green band and a deep purple to almost black centre.
This cultivar grows broader than many compact rex types. Its leaves rise from a shallow rhizome on fleshy petioles, which can carry pinkish-red hairs. In warm, humid conditions, mature plants can form a broader crown with overlapping older leaves.
Begonia 'Fireworks' has received the RHS Award of Garden Merit.

- Pinkish-red hairs on the petioles
- Broader rhizomatous growth
Care for larger Begonia rex 'Fireworks' leaves
Give 'Fireworks' bright filtered light so new leaves can develop without scorching. Keep it away from direct midday sun.
Keep the mix lightly moist during active growth, then let the upper layer begin to dry before watering again. Avoid soggy or compacted substrate around the rhizome.
Larger leaves need a mix that drains well and stays open after watering. Fine bark, pumice or perlite helps keep water moving and gives the roots more air.
The larger leaves mark at the edges more easily in dry air, so steady humidity helps. Airflow is important around the crown and between the petioles. Keep 'Fireworks' around 18–26°C and use weak fertiliser while it is producing fresh leaves.
Remove old leaves and faded flower stems before they trap moisture around the rhizome. In summer, it can go outside in sheltered bright shade, away from wind, heavy rain and strong sun.
Fireworks margin, crown and pest checks
- Brown margins: dry air, heat, watering gaps or strong fertiliser
- Drooping in wet mix: check the roots and rhizome
- Powdery mildew: leaves are staying damp without enough airflow
- Pale speckling: inspect for mites
- One-sided growth: rotate the pot regularly
Safety during Fireworks trimming
During trimming or repotting, clear away broken leaves and rhizome pieces so pets and children cannot reach them. Begonias contain calcium oxalates, with the rhizome and roots being the most irritating parts if eaten.
