Nibbles: Botanical gardens, Glass flowers, Remarkable trees, Rhubarb history, Expensive pumpkin, Back to the future, Quinoa glut, Citrus greening biocontrol

All of BGCI’s ex situ surveys on one cool page. Have they re-modelled their website?
Harvard’s glass flowers are totally cool.
The world’s coolest trees.
Rhubarb is cooler than you think.
I’m not sure paying over a thousand pounds for a pumpkin seed is all that cool.
Conventional breeding is cooler than genetic engineering. Cool quote of the week: “I tell my students they should drop acid before they go to the field, and just look at the plants and let them tell you what they are doing.”
Is the coolness over for quinoa? Jeremy unavailable for comment.
Cool Pakistani bug may help with citrus greening in the US. But don’t stop looking for resistance, y’all.
