Stoke’s aster is a genus of just this one species. I fell in love with this charming perennial the first time I laid my eyes on it when I first saw it at Plantarium exhibition in Boskoop, the Netherlands, where it was presented as a little known, showy perennial.

Divinity is a chance seedling of Stoke’s aster found by Paul David Babikow in his nursery In Florida, USA, in 2009. Looking at its divine flowers it makes sense why it was named that way. They are truly stunning with their diameter of 8-10 cm and almost white colour (with just a tiny flush of blue). They open from late July, and if regularly deadheaded they continue popping up until autumn. They take a few days before they mature completely to the flat shape but on the other hand they are quite long-lasting which is why they are very popular for cutting.

It makes rather compact and well-branched clumps with only about 30-40 cm tall stems. Leaves are evergreen in milder climates, medium green, broadly lance-shaped, long at the basal rosette, and quite short along the stems. Divinity Stoke’s aster was granted a US patent PP26164 in 2015.

Stoke’s aster comes from S.E. USA where it grows naturally on the edges of conifer woods, in moist, acid soil. It is hardy enough to be grown in Europe, too, down to zone 5b provided the soil is sharply-drained in order to avoid winter root rot. Grow it in full sun for profusion of flowers and make sure the soil is acid which will enhance the flower colour. Hardiness confirmed so far to -24 °C (USDA zone 6) and it should even withstand -29 °C.

  • STANDARD QUALITY - Plants of this group are 1st class quality with number of branches and overall density adequate to their size and age, considering they were container grown.
  • DE LUXE QUALITY - This label guarantees a luxurious quality of manually selected plants that, compared to their height and age, are exceptionally dense and beautiful.
  • EXTRA - These plants are usually mature and bigger specimens with exceptional overall appearance.
  • STANDARD (as described in the plant form) means a tree with a trunk of 190-210 cm and a crown at the top, unless specified differently. The commercial size for trees is their girth measured in the height of 1m from ground.
  • HOBBY - These plants are of the same quality as our standard-quality plants but younger and therefore cheaper.
  • SHRUB - a woody plant with branches growing bushy from the ground level.
  • HALF-STANDARD or MINI-STANDARD - a small tree with shorter trunk, its size is usually specified.
  • FEATHERED - These are trees with branches growing already from the base of the trunk and up along the stem.
  • GRASSES and PERENNIALS - Sizes given usually read the diameter of the pot or the clump, as specified.
