Lavandula x intermedia ‘Phenomenal’

lavxphe500Growing Lavender en masse here in the northeast has often been a risky thing to do. Lavender would suffer winter damage, and we would often find we had to replace plants here and there every winter. The good news is that after this recent cruel winter which caused more than its share of plant casualties, a new Lavender introduction came through unscathed. Lavandula ‘Phenomenal’, in fact, is looking pretty phenomenal.

Here’s the data. ‘Phenomenal’ was introduced by Peace Tree Farm Nursery in PA, after the folks there observed it for years in their trial beds. ‘Phenomenal’ tolerated extreme heat and humidity in summer, making it a good choice for hot summer areas, and was resistant to root diseases which often plague lavenders where winters are cold and wet. ‘Phenomenal’ begins blooming in late spring and carries on through July, with masses of intoxicatingly fragrant lavender blue flowers. Plants grow slowly at first, but reach large proportions …24″ tall and 36″ wide in several years time. Deer and rabbit resistant, it also attracts butterflies and grows best in full sun and well drained soil. Plants are super hardy too, …wintering over in zones 4-8.

  1. Would Lavandula Phenomenal grow in coastal mid Florida (Vero Beach)? We have a terrible problem with rabbits that gobble up everything in sight!

    • Molly, I’m not sure if folks have grown it as far south as Vero Beach. (zone 9?) I suspect that because it likes a good chill to bloom well, it may grow but not produce lots of flowers.
      Check with your local nurseries to see if they have had any luck with lavender.

  2. Thank you for the good advice re lavender. We may have to replace one for a client in Stow, MA, and will try your suggestion.
    On another subject, what are your thoughts on growing Monkshood (Aconitum)? My research shows that the plant is poisonous. A friend gave me some from her garden. Is it safe to handle?

    • I think this lavender is def worth a try. Monkshood is poisonous, and you should wash your hands after handling it, but I have has it in our garden for years, have transplanted it without thinking much and don’t think I ever suffered. Monkshood or Aconitum likes a slightly alkaline soil, so add ground limestone to the planting.

  3. Glad I saw this. I’ve been waiting for my lavender to gets its act together this spring (such as it is) …… still looks dead as a door nail. I’ll be right over.
