Flowers & Fruits:
- Each stem produces a single, pale lavender flower.
- The flowers have a bright yellow centre to guide bees to the pollen, found in the tubular flower neck.

These flowers are a favourite of the beefly, a small fly that looks like a bumblebee and hovers like a hummingbird to feed from the flowers.
