Roscoea humeana 'Alba'
Roscoea cautleoides
-
Roscoeas barely thinking about coming above ground here in Aberdeen!
-
Ditto in Denmark, even in the current heat wave we're having. Just tiny sprouts on cautleoides and being my usual impatient self I had to check that purpurea was still alive in the pot...
-
Roscoea procera
Roscoea purpurea 'Royal Purple Group'
-
Roscoea scillifolia is Roscoea alpina. I looked at the wrong number.
After discussion it should be Roscoea scillifolia!
-
Roscoea purpurea ‘Red Gurkha’
Roscoea purpurea 'Paul Bygrave's hybrids' exist in different colors.
-
Herman,
Very nice blooms! I just transplanted seedlings of 6 species of Roscoea. How long do they take from seed to bloom?

Marc, mostly it takes 3 to 4 years. Sometimes the smaller ones after 2 years.

Herman,
Thank you!

Roscoea cangshanensis - BWJ7848 smaller flowers
Roscoea purpurea 'Paul Bygrave's hybrids' dark flower

Herman, these look very much like scillifolia to me..

Tomte, these plants are around 20 cm high and scillifolia are higher (30-40cm)

It is R. scillifolia, R. alpina is rather different looking:

is R. purpurea the most vigorous species?
my March seedlings are already 20 cm high! but they started slowly...
on the other hand, a species whose label I've lost (but fortunately you'll be there when it flowers ;D) sown last year is still only 7 cm high.

I bought this one as Roscoea alpina more then 20 years ago. I know that it is not easy to have right names. According the book 'Roscoea' from Jill Cowley many pink scillifolia are wrongly named alpina. The leaves of alpina are wider. So I will change the name again.

Véronique, in our garden R. purpurea is indeed the most vigorous specie.

Herman.
Do you grow any other hardy members of Zingiiberaceae?

Marc, I have also Cautleya gracilis.
-
Herman,
VERY NICE! I'm growing 18 species in 4 genera; but they are all seedlings planted from last year's and the previous year's exchanges.

Roscoea purpurea
Roscoea purpurea 'Alba'
-
my juvenile R. purpurea plants don't have dark stems like this one.
I have Roscoea purpurea ‘Spice Island’ which has been in the ground for several years, but it no longer flowers because it is in too much shade, I think.
What is the exposure Herman? Does it get any sun?

Véronique, they get the morning sun, never in deep shade . Maybe it is a matter of feeding.

Roscoea purpurea 'Vannin' HWJK 2406 is a late flowering form.

Wow! Not one I've seen before - very "different".
-
Hi Herman,
Very nice! I can hardly wait until my seedlings flower; but I expect it will be 2-4 years.
-
You´re putting up a marvellous show of roscoeas, Herman! Very beautiful specimens! I´m so sorry that none of mine reappeared this year, due to the slugs, I think. Nevertheless, I couldn´t resist to buy some exciting new ones recently. For safety´s sake, they are residing in the green house.
-
it's sad when slugs kill a whole plant...
here's the first flower from a 2/3 year old seedling. the one whose label I've lost
the plant is still small (15 cm high).
perhaps you could identify it?
a 2 cm flower
-
my plant was bought from a nursery without a cultivar name:
it's been faithful for years, but I think it's in too much shade now because it's getting longer.
it did flower a little in september.
the best time to move it is this autumn when it has lost its leaves?
I thought it might be ‘Spice Island’; if you have another idea...

It may be R. scillifolia - I sowed this one last year, and it flowered the same year, also at this time. It will remain a small plant with tiny flowers.

It looks like R. scillifolia!
-
thank you both.
I did indeed sow that at one point.
