The big leafed rhododendrons are mainly beyond resurrection even with watering. Hugely depressing and we are very nearly back to 1976 when all the mature ones died throughout Cornwall.
Already dead and dying Hydrangeas by the Green Gate.

Rhododendron suoilenhense has dropped its old leaves and the new growth struggles despite watering. Not much hope of survival here long term.

Our second plant of Mallotus japonicus has, I believe, female flowers.

I have always read that Mallotus japonicus has root suckers. Here is the first evidence.

Sitting in the bath I wondered if this plant was actually Meliosma dumicola? The reality is that it is Daphniphyllum glaucescens which does not yet feature on the IDS website.

A wonderful roadside triangle of betony or Betonica officinalis (formerly Stachys officinalis) under a signpost near Nancor Farm on the road to Carwinnick. Tarmac on three sides and, apart from a couple of knapweed, nothing else growing on this small area. There is betony in fairly nearby hedges but this lot has shown up this year because of no grass cutting at all. Long may it continue!
Time to get the autumn/spring rare plant orders for Caerhays into the pipeline before the European nurseries produce their autumn availability lists. Lunaplant in Germany promise a delivery of a number of their new magnolia hybrids bred by Michael Gottschalk (and others) which we had identified and talked about in the spring. A notable magnolia breeder but not a large nursery. A well-known Belgian wholesale nursery declined our £20k spring order due to Brexit. Will they relent now, as most big European nurseries have already done, and include our Caerhays order for a new collection of Celtis and Zanthoxylum species with the Burncoose order? Two years ago we brought in 20+ new species of cotoneaster and, last autumn, we added a dozen more to the collection of Crataegus species from all around the world. These have done well and are ready to plant out in one spot this autumn. The Cotoneasters and Crataegus are well photographed in this diary.
I thought I would try to obtain a few more very obscure genera:
Campytoptris macrocarpaDichotomanthes tristaniicarpa
Mediago strasseri
Ostryopsis davidiana
Phoebe bournei
These are generally dull shrubs with boring flowers but of considerable botanical rarity and exactly what we should be growing here to entertain, confuse and educate. Do not worry I had to look all of them up as well!
