Proteas and Leucadendrons Discussions

I recently had Protea Brenda in a vase for 4 weeks!  Sure I had to trim some of the foliage back as it dried in but the flower lasted a full month.  Have others shared this experience of having Protea?  I used to think they didn't last long but have discovered that when you get a fresh, quality protea with good post harvest treatment they can be very long lasting.

Protea are very hardy and super long lasting.  I have had many protea last for weeks!   I find they usually outlive their vase-mates, and they do look stunning all by themselves once all the fillers have expired.  They are quite worth the price for this kind of performance!
 

I've been told the black foliage is due to lack of sugars (perhaps in post harvest or in the field?). That said, a floral preservative in the vase should help stave off the blackening and changing the water with new preservative should keep them nicer longer!
