The only Pink Cudweed I've found is above the Upper Tilley trail. When I first managed to get close enough for some decent photos, I noticed immediately that the plants had a spicy smell that lingered on my fingers. As soon as I got home, I went to my spice cupboard to try and match the scent. The curry powder was the closest smell! After the managed fires on Tilley Hill (early 2015), all of the Pink Cudweed plants disappeared. But by 2017, I was able to spot a few of them again.
This is about all of the Pink Cudweed plants I've found in the park.
