Oxypetalum caeruleum

Dec. 6: Floral advent calendar: Tweedia coerulea

The specific epithet of my next flower, Tweedia coerulea, gives away that it is yet another of my favored elusively colored blooms. “Coerulea,” quite simply, means blue. This plant is sometimes seen under the synonym Oxypetalum caeruleum, but the meaning of the specific epithet stays the same.

This is another South American native photographed at Derry Watkin’s amazing nursery near Bath, Special Plants. After meeting Derry during her talk at the Parham House garden weekend, my husband and I stopped in to visit her on a weekend trip to Bath this August. It was hard to take a step in her nursery without oohing and ahhing, and the visit got even better with a walk around her unique garden, which is the work of 20+ years by a serious plantsperson. Derry, an American, married a British architect who designed her a house with a wall of Streptocarpus instead of curtains. I’ve stood in this house, and seen this wall and…be still my heart.

Derry has long lived in the U.K., starting her world-renowned nursery at age 40. She told me the nursery business doesn’t make any money but sure is a fun lifestyle. Of the myriad fascinating plants that stood out to me that day, this Tweedia has a color, uniqueness, and vivacity that can’t be ignored, much like Derry herself.
