The old survivor
Here is the oldest member of my motley orchid collection, which also has the honor of being the first and only orchid I have ever successfully rebloomed.
The plant has seen better days in the nearly 3 years it spent in my possession. By the time it came with me to New York, it had only one decently-sized leaf and two roots to support itself. In the months since it grew the two small leaves you can see in the picture. Usually a healthy phalaenopsis should produce new leaves that are as large or larger than the older leaves. The miniature size of the two newest leaves on this plant are a clear sign that it has experienced damage to its root system.
The plant is a tenacious little noid though, and in the past month it has sprouted 5 healthy new roots, which have been speedily growing into the media. At this rate, I expect the orchid should have fully recovered by next blooming season.
