Both entries list full sun (6+ hours). Light alone does not distinguish this pair in the catalog; compare the temperature and care-level entries below.
Rajnigandha (Tuberose) has a recorded range of 10–38°C; Sthalpadma (Changeable Rose) is listed at 5–38°C. The recorded ranges overlap from 10 to 38°C. That overlap compares the draft entries; it is not proof that either plant will suit the spot.
Rajnigandha (Tuberose) is marked moderate, compared with easy for Sthalpadma (Changeable Rose). Treat that as a planning estimate, then ask which care tasks each plant needs in your conditions.
A comparison cannot set a watering date. Check moisture first: pot size, growing mix and current weather change how quickly a container dries. Record what you notice and decide when to check again.
Read the RHS guide to watering containers for general container advice, or use Plont’s plant observation checklist. The RHS source supports this general advice; it does not verify the species-specific draft values above.
