I never did get round to re-locating my Roscoeas to a more shaded part of the garden. First one to flower this year, Roscoea cautleyoides 'Jeffrey Thomas', some others in bud.
-
Heck, mine are just breaking surface ::)
-
Ours haven't even broken the surface yet.
-
Some of ours are a mm above the surface, many species not showing yet. You've shocked me with this one David :o :o
Wonderfully 8).
-
It's his sunny smile that pulls them up towards the light. ;D
-
Last year I had a very nice clump, but this year we had a tough freeze in the end of January after a mild start of the winter. That also did decrease Roscoea cautleoides. This year I only have 4 flowering size R. cautleoides. Let's hope next year will be better.
-
A nice clump -- Roscoea humeana? -- a gift from a good friend. Most other roscoeas are just showing leaf or color.
-
I would think that is R. humeana, Claire... and very lovely it is too.
-
Another roscoea -- marked R. tumjensis (though the name may not be correct). R. cautleyoides is now flowering, with R. auriculata and an unnamed roscoea not far behind.
-
Good article in the June edition of The Plantsman which is a report on the recent RHS trials at Wisley
-
A lovely clump of R humeana, Claire. My two clumps (purple and alba forms) are only just coming through the soil.
Here's both the yellow and purple forms of Roscoea cautleyoides flowering in the garden today. 'Pennine Purple' is not so advanced.
-
Those look good, David... ours are seldom out of the ground before July - certainly no sign of them yet.
-
R. humeana
I am particularly pleased with this pot of R.humeana, flowering today from seed sown in December 2009. The colour is more towards a 'plum' colour than is typical, and is I think very similar to that of forma tyria. Particularly unusual is the white / colourless stripe running down the length of the dorsal petal, on one of the plants. It remains to be seen if this is a constant feature for this plant, and if so, if it is stable enough to return year on year.

Interesting form Ron.
Roscoea cautleyoides "Pennine Purple" now in flower but got a bit battered by the rain last weekend.
R. humeana alba - started after the rain stopped so looking good. Funny though the purple form is lagging behind, only about 5 cm above soil. ???
-
Another roscoea -- marked R. tumjensis (though the name may not be correct). R. cautleyoides is now flowering, with R. auriculata and an unnamed roscoea not far behind.
WOW that is a fantastic thing,never heard of that sp Claire.
Ron and DaveM superb dark Roscoeas.
-
Having missed photographing my Roscoeas this year, apart from the first one to flower, here's my last one Roscoea humeana 'Purple Streaker'
-
Its growing beautifully there David. 8)
-
Thanks Ron, it gets plenty of water, and shade :P
-
Thanks for posting your picture of 'Purple Streaker', David. I have a very similar roscoea just coming into flower that was acquired with no name attached. From descriptions online it might be Roscoea purpurea 'Purple Streaker'. Any opinions?
-
Your photo shows really well how amazingly transparent some flowers can become as they age, or after a lot of rain ( as is usually the case here! :P )
-
Any advice on the best time to divide roscoeas?
-
I've always done it when they're dormant (which probably covers most of the year!) in early spring.
As a plus you also get a fabulous ginger smell from the roots when you handle them. :D
-
Bought this from Hartside Nursery at Perth SRGC show this Spring.
Roscoea 'Harvington Evening Star'
-
Very nice Roma, it's a nice deep colour. I bought a white one but was disappointed as it is really pale pink.
Angie :)
-
A nice species Roscoea which I don't have a name for. It is about the last to flower and has lovely glaucous blue leaves. Any ideas?

R. schneideriana - Three years old from seed.
and,
R. scillifolia scillifolia ( pink ) in front of R x beesiana ( yellow and purple to varying degrees ),
-
Roscoea 'Monique'
Another new one this year. I think I like the dark one better.
-
Roscoea 'Monique'
Another new one this year. I think I like the dark one better.
This is another named R x beesiana isn't it Roma? According to Jill Cowley ( The Genus Roscoea, 2007 ) its named after the propagators wife.
:-X

R.australis
-
A nice species Roscoea which I don't have a name for. It is about the last to flower and has lovely glaucous blue leaves. Any ideas?
Susan
Susan, could your plant possibly be R. wardii ? The flowers look right for this species ( in shape etc, but colour is maybe too 'purple' ) and I have recently been reading that it sometimes develops glaucous leaves.
Although there is also R. cautleyoides 'Old Purple' which is also said to have bluish leaves. :)
-
R. auriculata
Always the last to flower for us. Perhaps not the most classy of the Roscoea, and sometimes the clumps look a bit scruffy ( as ours do in these pictures ), but its one of the easier ones and clumps up quickly. Often confused with R.purpurea.
-
Only have the one Roscoea a gift from Peter Farkasch and here it is R. Red Gurkha (not sure if I have the H in the right place there :P
-
Oh Roscoea :D
I love this plant , i offered to me most than one hundred plants
I have not R. Red Gurkha !

If you've some seed of other species ...i was very interested to test that !

It's my Roscoea in beginning of the year when i received plants.

Wonderful photo of the result few month later (Photo by a friend-Foromist <<flupke>> with whom I made a bulk purchase of Roscoea )

Great success.

Collecting seeds for exchanges - I got this small species as R. alpina. Is this the right name?
-
No, sorry Anne, its R.scillifolia scillifolia.
A very tough resilient sp. and a profligate seed producer. Also available in black ( well very dark purple ) as R. scillifolia atropurpurea.
A lovely plant ;D
-
Thanks Ron! I agree with both descriptions.
-
Glad to help Anne, :)
There is a lot of variation with R. scillifolia scillifolia. The leaves can be long and thin, (on tall 20cm plants), or short and fat ( on squat 10 cm plants ). The degree of exsertion of the flowers is also very variable. All forms are still very prolific in the seed production, and will flower easily in their second year.
