Roscoea 2024

Roscoea humeana 'Alba'

Roscoea cautleoides

[Maggi Young]

Roscoeas barely thinking about coming above ground here in Aberdeen!

[arisaema]

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'

[Herman Mylemans]

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!

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:

[Véronique Macrelle]

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 ) 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.
