One of the most extraordinary flowers you’ll ever see belongs to a group of fruiting vines you’ve probably eaten on many occasions and that’s the passionfruit, or Passiflora. There are a staggering 500 or so different species in this genus and most have fabulous flowers. In particular the ornamental species Passiflora coccinea or Scarlet passion flower. It’s open star-shaped bloom is over 10cm across and has that typical prominent stamen arrangement, but the colour is glorious. It’s a deep scarlet red and is quite the contrast against the deep crinkly green leaves. Passionfruit plants are pretty short-lived - maybe only a few years  - so you may need to take cuttings to replant every few years. But for most of the year you will see a flower or two on this fast-growing climber.
