Centratherum punctatum (Porcupine Flower) - A tender perennial to 1-2 feet tall by 2 feet wide with coarsely-toothed heavily-veined dark green leaves that smell of pineapple when crushed. The lavender button-like 1 1/2 inch wide flowers bloom from spring into summer. Does well in full to part sun with moderate water. Hardy to about 30-32. Root hardy to about 25 degrees F and often reseeds in the garden. Attractive to butterflies. This plant is sometimes called Manaos Beauty, Pineapple Thistle and Pineapple Weed, Brazilian Button or Brazilian Bathchelor's Button. The foliage is softer and easier to eat than Pineapple Sage (Salvia elegans). The name Centratherum comes from the Greek 'kentron' (spur) and 'anthos' (flower) referring to the flower having a spur-like base. Some references note that this plant is from the West Indies and others list it as from Brazil. We first noted mention of this plant in Pacific Horticulture where an article in the Spring 1993 issue noted it as a good companion plant to roses and the Spring 1995 issue featured a picture of the plant growing as an understory to black bamboo. We grew this plant from 1996 to 2006 but discontinued because of lack of sales and its somewhat ephemeral nature in the garden.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Centratherum punctatum.
