Hydrangeas – the ‘Change Roses’.

Sunny June, the month most closely associated with the garden’s sunbathing divas and just as our English roses are budding, not far behind them are those plants that prefer quite different conditions. They are of course the hydrangeas, (from the Greek water vessel or ‘hydria’ which seemingly resembles the seed pods). Whatever the derived association, hydrangeas are renowned water guzzlers and abide in semi- shade. (And this latter part of June has provided such conditions!)

Since the Japanese name derives from ‘a gathering of blues’, the native soils must be acidic as well as rich in aluminium ions, the magic combination that turns most of the common varieties of pink/red hydrangeas to the blue spectrum. Whereas in my previous London garden of alkaline soil, all the H. macrophyllas, including the tiny florets of ‘White Wave’, were pinkalicious!

Since I had previously gardened in shade, hydrangeas were an obvious plant choice, although the London soil was rather too well-drained and they quite often gasped in summer. However, the wet/dryish care they received is probably better than constant superficial watering as it encouraged the roots to reach further down, which is beneficial to these large, top-heavy shrubs.

I brought two cuttings with me from that garden in 2019 and both have flourished. The H. macrophylla I’d first picked up from a roadside plant sale as a cutting which the gardener had labelled ‘apple blossom‘ though no such name officially exists. It was no bigger then than this third generation one (striving to flower now despite its diminutive size) but the large leaf is a clue to its eventual size!

The other cutting that I brought is actually a faux hydrangea – Schizophragma hydrangeoides ‘Moonlight‘, a climbing liana from the woodlands of Japan with bracts and infertile flowers similar to a lacecap hydrangea. It is a slow grower initially, but will eventually reach over 30 feet. For now it is a potted juvenile and flowering for the first time.

My current favourite hydrangea is a bi-coloured serrata – ‘Kiyosumi. More compact, hardier and with remarkable leaf colour in both Spring and Autumn. Serratas inhabit the mountain regions of Japan, and I’d like to collect more for my next garden in the Derbyshire heights. These hydrangeas have the added benefit of being edible as the leaves make a sweet tea called ama-cha, 甘茶.

I am forever grateful to the plant hunters who brought us these wonderful plants, and their history is entwined with romance too.

For Westerners, hydrangea can be seen as a symbol of silent devotion, as its scientific name, otaksa, appears to refer to Otaki-San, a woman from Nagasaki’s pleasure quarter, who was the mistress of the German naturalist P.F. von Siebold, who went on to introduce ajisai to Europe“. Tsukublog

Countdown in June

A summer’s sun is worth the having” ~ French Proverb

As soon as washout May turned the corner, the sun’s shone down on June…so far. Being away next week for a little while, I’m now anxious about drought, though a neighbour will pop in to water – I hope before the plants take their last gasp.

And this is the final full month for me and my plants in this small gravelled courtyard. It has been a delightful spot to garden in, for the past 18 months. In such an intimate space I’ve come to fully appreciate the plants, whilst Covid lockdown gave me the time and impetus to catalogue them too.

Some plants are still nameless and hence ex-catalogue, and seeking to ID them from the internet. is not the most reliable source. A London gardener who gave me a giant hosta thought it might be ‘Big Daddy’ but the leaves are not blue-green enough whilst the flowers are supposed to be white rather than lilac. I am currently betting on “Empress Wu”

Most of the plants will be travelling with me to Derbyshire. The more colourful ones, including Lewisia and my favourite Salvias, will go in my daughter’s garden, adjacent to me, so I can still visit them! Some like my current selection of Nemesias are too garish for the planned Japanese themed garden and being frost tender will have to be protected against the Derbyshire winter. I will have a small glasshouse for them but since they are short-lived it hardly matters.

I don’t want to leave the garden bare for the next occupant and have planted up the three big pots which belong here. This includes clematis ‘Rouge Cardinal’ – just starting to flower now so I still have time to enjoy it.

Before leaving, I also have the satisfaction of having restored an old, resident climbing rose back to full glory. It produced no flowers last year but now with pruning and feeding it is busting out all over in single white flowers. The aphids are also appreciating this show! Garlic spray is some help but mostly this tough rose seems to be impervious to the predation.

Astronomically speaking, it isn’t summer yet but I’ve added some of this month’s blooms to the summer flower portrait gallery. After all, next June’s Japanese style garden, will be a very different palette.
