Purple orchid bouquets wrapped in crepe paper that bring a universal message of love, beauty, wisdom, thoughtfulness, luxury, strength, and affection. Blooming in every colour except blue and black, orchids are known for their showy and sweet-smelling flowers, making them some of the best fragrant outdoor plants. Some orchids, like epidendrum orchids, thrive in the garden, while others like paphiopedilum orchids make for great indoor plants. Orchids may have a reputation of being difficult to care for, but certain types like Phalaenopsis orchids can be some of the easiest flowers to grow.
