June 2025 in the Northern Hemisphere

[Knud]

This last week I visited our local botanical haven, the Stavanger Botancal Garden, a couple of times. Right at the entrance the Chilean Firebush, Embothrium coccineum, was ablaze. Meconopsis punicea was at the tail end of what had been a good flowering for most of May. Lilium pyrenaicum was at the start of its show.
In the rock garden there were two in bloom I had not seen before, Aethionema kotschyi and Erigeron leiomerus

A last one from Stavanger Botanical Garden, a beautiful Edelweiss, Leontopodium nivale ssp alpinum.
In our garden Edraianthus horvatii has just started flowering, as has Daphne alpina.

Another few species started flowering in the rock garden the last weeks. Campanula Molly Pinsent only the last few days, I keep it in a trough to protect it from slugs. The Caucasian crosswort, Phuopsis stylosa, grows in the rock garden, and started a few weeks ago. One can see why it is called ‘stylosa’. The instensly blue flowers of Moltkia petrea are always a surprise once they open from their purple buds. This plant is 10-15 years old. The last saxifraga to flower here is one I have as Saxifraga cochlearis ‘Minor’. Rhodohypoxis have of course been blooming for weeks already, but after a light drizzle last week many of them donned quite large water drops in their flowers.

Thank You for the many pics shown in May and June, Knud! Last month, I marvelled especially at the rare Sorbus filipes! Do the leaves set off the white fruits as well as Sorbus fruticosus? I´m very pleased with mine grown from seed.

We spent a few weeks in Sweden, where I found a clone of Lily of the valley with 13 flowers to the stalk - something hybridizers aimed at in the past.



A special feature of Sweden are the remnants of abondoned gardens, this is a double form of Narcissus poeticus growing wild.



On Öland, there are lots of irises growing by the roadside, this is Iris x Flavescens.



Another spot showing an iris called Iris x sambucina in Sweden, together with naturalised oriental poppies.

Some orchids on Öland:

Neottia nidus-avis



Orchis militaris



I´m not sure about this one:



An attractive hemiparasite: Melampyrum cristatum

[Mariette]

In Västergötland, Geranium sylvaticum was flowering in a variation of colours not found in commerce.







Another hemiparasite: Melampyrum nemorosum, aptly named Natt och Dag, Night and Day, in Sweden.

An attractive Geum x intermedium

Finally two pics from back home. One of my sons made an interesting observation. He prepared the loam in his garden with sawdust of oak and spruce to plant blueberries. The flowers of the neighbouring hydrangea turned from pink to blue, but only those closest to the blueberry.

Blue berries like an acidic soil, this soil pH also will give blue hydrangeas.

[Mariette]

Thank You, Jeff! My son was interested to try an eco-friendly way to achieve acidic soil for his bluberries instead of the usual peat. Obviously it works well, also to turn hydrangeas blue. The surprise was that not all flowers of the hydrangea turned blue, but only those closest to the blueberry. Hereabouts, chemicals are sold to achieve blue hydrangeas. Sawdust of spruce and oak might be a good alternative where available.

Flowering & setting seed in the garden this June.
Clematis fremontii white seedling

Well, Mike, I was admiring the Clematis fremontii - then I saw the Sarmienta repans - crikey and double crikey! What fantasic flowering!!
