Phormium ‘Platt’s Black’
Platt’s Black New Zealand Flax
2′ x 2′ New Zealand flax is an excellent, slow growing, accent plant. Phormiums are very tough perennials that require full sun or light shade, moderate water and a fairly well drained soil. Good at all elevations. Platt’s Black is a smaller selection with nearly black leaves
Watch out for mealybug, they get into the crown of the plant, between the leaf blades. Oddly enough I have found that planting large numbers of Phormium seem to have more mealybug than just a few. Ants are farming these insects, as they do with aphids and scale. We use Talstar granules, a synthetic pyrethoid, to sprinkle in and around the crown. This keeps the ants away and really slows down the mealybug too.
