Buy Agastache 'Blue Boa' (PBR) Mexican giant hyssop: A magnet for bees and butterflies

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: well-drained, fertile soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: hardy (borderline)

    This new hyssop is dependably hardy to -5C, and it produces its fattened spikes of deep violet-blue flowers over a long period from midsummer. These not only look great, but they will also help attract lots of beneficial insects, so it's perfect for a wildlife-friendly garden, while the rich green foliage, which releases its licorice-like aroma when gently bruised, makes it valuable for sensory gardens.

  • Garden care: Don't cut back the faded flower-stems in until early spring, as they provide interest in the winter months. Lift and divide congested colonies in spring.

I purchased this plant late in the season last year and kept it in my log cabin during the winter to protect it as it is not fully hardy, i put it outside after all risk of frost had past, it immediately took off and grew very quickly producing masses of beautiful flowers continually for at least five months! mine is in a large pot on my patio it is beautiful and would recommend it,i cannot praise it enough.The bees love it as well.

I purchased this plant late last year in 9cm pot it was very small and i was slightly concerned that it would not survive the winter, however i planted it in a terracotta pot so i could put it in my log cabin over winter with fleece covering it for protection, i put the plant out after the frosts had finished after a slow start it really took off ! it is now covered in beautiful long lasting purple flowers......great plant in the border or large pot on a patio, thank you crocus

It was tough keeping this new plant going during the drought

It was so hard to keep it alive during the drought but I think it has survived! I've only given four stars because I'm not sure it has survived.

I bought three plants and they did really well in last years hot summer. The flowers are a beautiful blue and really stand out. Looking forward to them bulking up this year.

It's quite a straggly plant reminds me of stinging nettles. But wow does it flower for a long time. Flowered into November. It's not affected by slugs and snails. Although straggly it doesn't need any support, I don't know how it's going to over winter but I won't cut back until spring. Excellent plant and lovely purple colour, I bought more for other parts of the garden. And although it's January it hasn't died back yet.
