I feel flattered and honoured to have a terrific review of Passiflora ‘Snow Queen’ by Dan Cooper aka ‘The Frustrated Gardener’

‘In the four months since I planted it, ‘Snow Queen’ has grown 15ft from the base and is producing ten or more flowers every day, each lasting 48 hours. At first the self-clinging stems produced only leaves, some larger than my hand, but in early August flowering resumed and looks set to continue through autumn. The amount of growth is staggering when you consider the pot my plant is growing in measures only 12″ in diameter.’

Excited to attend with Ann Morling the recording of Gardeners’ Question Time in the Temperate House at Kew Gardens, a week before it was open to the public. £41 million spent on the refurb but looks incredible. Just need to wait 50 years for all the plants to grow into it. And I even got to ask a question about Passiflora seed germination! GQT iPlayer recording.

I’ve just read Carlos Magdalena’s book, ‘The Plant Messiah’. Inspirational in so many ways including various thoughts re my Passiflora breeding. A book that says enough is enough. Not everyone, indeed few of us, have the courage to put our lives on the line seeking out plants in remote and sometimes dangerous places, but each of us can do our own little bit. See my review.

Plant Breeders Rights Granted (48,160) by CPVO  for the Riverside® Hybrid Passiflora ‘Snow Queen’. This has been a long slow process but we got there in the end thanks to the endeavours of PlantHaven International,inc. Picture shows breeder Myles Irvine with the ‘Snow Queen’ herself, Natalia Walaszek.

The off season Well in a way but the work goes on. A surprising number of the more tropical species flower in December/January as flowering is triggered by shorter day length. Pictures from 2017 of an interesting new polyploid hybrid. Unusual in that it does not open any further than this. Sleeves rolled up for a productive 2018. Only release the best!

September 2017

Royal Botanical Gardens Kew A fabulous behind the scenes visit to the nurseries at Kew catching up with both Rebecca Hilgenhof & Carlos Magdalena, author of The Plant Messiah. I saw more Passiflora than I could count and indeed many other incredible plants. A day to remember and good learning experience. Picture shows Rebecca holding a huge Passiflora macrophylla leaf. It is one of the Astrophea, which are trees rather than climbing vines.
