This is definitely the most unusual plant I've got growing in my garden. I found it in a local nursery just last year, so mine is still a baby. It's been quite hard to find a lot of information about it ... so I'll share the little I know.
It's from Costa Rica apparently ...in the Euphorbiaceae (Spurge) family ... and grows well in tropical and semi-tropical climates. It needs lots of bright sunlight ... will grow in full sun and partial shade ... likes a moderately moist soil ... and thrives in warm conditions. Apparently once it is established, it is somewhat drought tolerant.
This Dalechampia is a fast-growing evergreen climber with green, heart-shaped leaves ...
and bright purple blooms. It's commonly called the 'Silk Crepe Flower' because the bloom does feel like silk.
The purple part is in fact a bract. The creamy-brown bit in the middle is quite sticky ... the little red heart-shaped things are tiny flowers I think, but I'm not certain.
And then there are these cauliflower-looking things that appear after a while ... what these are I hazard to guess!
Then finally the bracts fall off, leaving the tiny heart-shaped flowers with the heart-shaped leaves in the background.
Seems like rather a perfect plant to talk about on Valentine's Day!!
