Here’s a better shot of the Yarrow Broomrape with AlarmGnome temporarily disabled. It really is a very beautiful thing, much more so than many of the broomrapes which tend to look dead even when they’re alive. The reason for is that they have no chlorophyll and so aren’t green at all. They don’t need to make food in the usual photosynthetic

way because they are in fact obligate parasites living off the food and water in neighbouring plants by tapping into their roots. Many broomrapes are very specific and are named after their hosts. Yarrow Broomrape parasitizes yarrow - a very familiar plant which makes it all the stranger that this broomrape is so rare.

One of the island’s rarest flowers is in safe hands. The rather beautiful Yarrow Broomrape (the purple flower in the picture) has acquired ‘AlarmGnome’ technology thanks to a grant from the SBPF (Spurious Botanical Projects Fund). If anyone should approach the plants AlarmGnome issues a first warning: ” Step Away from the Flowers”. If this doesn’t ward them off and they get still closer risking harm to the Broomrape, then AlarmGnome gives a second warning of “Back Off Now, or Suffer”. If this still doesn’t deter the deranged intruder then AlarmGnome becomes AttackGnome and you really don’t want to know what happens next.

Suffice to say, it’s not pretty.
