What are the rules and regulations to select flowers for Perumal Tiruvaradhanam? If fragrance is an important requirement, the Kanakambaram flower has no fragrance; can we offer Kanakambaram for Emperuman?

There are regulations on the types of flowers that can be used for Perumal Tiruvaradhanam.
On offering the Kanakambaram flower, one must consider whether it is being offered to a temple Perumal, or the Perumal at one’s home. Kanakambaram can certainly be offered to Perumal at the temple; it is said that it is better to offer, white flowers as far as possible that are fragrant to Perumal at home. Shortly we will share a PDF on this subject.
