I couldn't find a posting about weird or unusual growth on plants just some questions about about individual plants. So.... post some pictures and comments here.
For instance the the odd color and shape of this desert rose, Adenium obesum is caused by a virus.
This is a crested Euphorbia lactea
One of the old cherry trees planted in the DC Tidal Basin area. Gifted from Japan they are over 160 years old, more than double the usual life span of this species, Prunus x yedoensis
And another, twisted and contorted yet still flowering annually
