Perennial Plant of the Year 2019

GARDENERS RESOURCESPERENNIAL OF THE YEAR

Stachys monieri ‘Hummelo’

A cousin to the familiar Lamb’s-Ears, but not at all similar. This is a clump-forming perennial, forming a low mound of crisp green foliage. In early summer the upright spikes of bright-purple flowers appear, which attract bees to the nectar. Removing faded flowers will encourage more buds to form for weeks on end. An interesting and unusual perennial for near the front of the border, or in containers. Plants may be clipped back hard immediately after blooming, to tidy up the clumps for the rest of the season. Easily divided in early spring.
Prefers a sunny location and is hardy to zone 4.
The Perennial Plant of the Year is selected by the Perennial Plant Association. The following criterion are used in selecting the winner.

  • Suitable for a wide range of climatic conditions
  • Low Maintenance
  • Pest and disease resistant
  • Readily available in the year of release
  • Multiple season interest or excellent foliage
  • Easily propagated by asexual ( division or cuttings) or seed propagation

‘Honorine Jobert’ has pure white flowers, about 2-3 inches across. Each flower has a single layer of 6-9 sepals and a central eye of bright yellow stamens. (In this case, the sepals are similar to petals, but they also function as bud scales enclosing the inner flower parts before it opens.) The leaves are medium to deep green, 3-lobed and slightly hairy, creating a 20-24 inch tall mound of foliage.

When blooming, the flowers are produced at a height of 24-48 inches, on tall, slender, branched stems above the foliage. This creates a nice mid-level floral display in any garden planting. Plants are very floriferous, meaning each plant produces many flowers.

Other cultivars available have flowers in pink, dark pink or purple, some with semidouble or fully double flowers. Blooming begins in August or September and continues until plants are killed by freezing temperatures. ‘Honorine Jobert’ is an old cultivar, originating as a sport (a natural mutation) from a pink-flowered plant.

It was discovered in the garden of M. Jobert in Verdun, France in 1858. According to Allan Armitage, author of Herbaceous Perennial Plants and University of Georgia Professor Emeritus of Horticulture, ‘Honorine Jobert’ has been a popular plant in European gardens since the beginning of the American Civil War and it’s still very popular today.
