May 2025

[Martin Bohnet]

No one want's to start May, one of the most beautiful months at all? Well, at least here in temperate Europe. OK, so I'll do it...

lets start in the Garden, and let's start with a mystery: A spring-flowering, tall and slender Acis should be Acis trichophylla

, but I don't find any records of me getting one. Definitely not nicaeensis, that's more coarse and not even half as tall. No idea where that came from.

Next is my striped Convallaria majalis

- it already grew a reverted pure green leaf on one of the stolons, which I had to pull - always have to be careful with reverting variegated forms. Lets stay with borderline geophytes and add in Tulbaghia simmleri

(potted) and, in the bog, Pinguicula grandiflora.

May is also a good orchid month - here in the garden you can see Calanthe tricarinata

Height:	20-30 cm (0.7-1 ft)
Flower Colors:	green, brown

in front of Cypripedium 'Barry Phillips'

Height:	30-45 cm (1-1.5 ft)
Flower Colors:	yellow, green
Flower Season:	late spring to early summer
Climate:	USDA Zone 5-8

(at least the biggest stem with 2 flowers wasn't eaten up by caterpillars...), but yesterday I also went to my favorite place in the Swabian Jura to find some in habitat: Orchis militaris

Height:	20-60 cm (0.7-2 ft)
Flower Colors:	pink, purple
Flower Season:	early summer
Life form:	tuber
Climate:	USDA Zone 6-8

, Ophrys sphegodes

Height:	30-45 cm (1-1.5 ft)
Flower Colors:	green, brown, patterned
Flower Season:	late spring

and some Orchis mascula

Height:	45-60 cm (1.5-2 ft)
Flower Colors:	pink, purple
Flower Season:	late spring to early summer
Life form:	tuber

in the background of a not yet opened and thus hard to identify Orobanche-Species. I actually was surprised to find them in rather good condition as we had a VERY dry spring up to today - in the last 24 hours we had as much rain as in April and March, respectively which all wasn't much: 27 l/m³ each.

To finish the excursion to my Wasserberg I found a rather dark form of Arum maculatum

- Not sure if there could be anything mixed into this?

Few things in bloom here in Kentucky
Arisaema kiusianum
Eucrosia aurantica (yellow)
 and E eucrosiodes (red)
Sprecklia howardii
Collonox albucoides (supposed to be a winter bloomer)
Resnova magaphylla

Thog brittenea

This last fall I got some Iris spuria from the EU Bx, donated by Martin Bohnet. The first one has opened - yellow form.

Dear Wylie,

It's not really a surprise that your Island is about a month earlier then my garden, for me those will flower in June (so these pictures are NOT current). I am somewhat surprised by the color though - I offered both a clear yellow (Iris xanthospuria - esque though most likely a hybrid) and a form that ends up orange-brown for me - it is VERY likely the latter one is quite temperature sensitive and will stay lighter in your likely less extreme temperatures - in the beginning of June I easily reach 30°C, so I think your perceived yellow is indeed the Imperial bronze.

spuria iris?

I had this happen to a daylily I bought years ago from someone who lives Northwest of Munich. He claimed it was orange, but in my garden it is a definite brown. This Iris has colored up a little and looks more orange, now.

Martin,

This is the orange-brown iris I received in the exchange from you.  It just fully opened today in Armilla, Granada, Spain.

Some Aroids are flowering in the garden right now:

Helicodiceros muscivorum: flowers are impressive but short lived. They do not smell as badly as I had thought 

Dracunculus canariensis in the open ground in my shade garden 

Zantedeschia aethiopica ,,Pink Lady" the pink tinge is most pronounced on the bud and will fade as the flower ages 

Dracunculus vulgaris. Impressive flower, again, not as smelly as anticipated.

Zantedeschia aethiopica ,,Glencoe" one of the best named varieties

Hi Uli

Maybe your olfactory organ is not up to snuff?
