Tweedia caerulea (Blue Flowered Milkweed) - This twining perennial from Brazil and Uruguay grows 2-3 feet on its own and can reach to 10 feet with support. It has 4 inch long gray-green leaves that, like the stems and inflorescence, are covered with fine soft hair. In the summer appear the clusters of star-shaped pale blue flowers with darker turquoise centers that are followed by 4 inch long pods. Plant in full sun and irrigate regularly. Although evergreen it is best to tidy up this plant by cutting it back in early spring. It is often plagued late season by orange aphids which although look somewhat attractive juxtaposed against the blue flowers, should be hosed off or otherwise treated. What color blue is this plant? It sure is fantastic and we have heard some people refer to it as "yuppie blue".  Information presented on this page is based on research that we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it the nursery's garden and in other gardens we visit as well, as well as in our nursery crops in the field. We incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they include cultural information that would aid others in growing  Tweedia caerulea.
