Hi there any experts there can tell what costus are these from the leaves only? The leaves are furry

Plant 1

Plant 2

How do you induce flowering? Or is flowering only possible when planted into ground?

Thanks in advance
:rolleyes:/>

:)/> looks like costus curvibracteatus to me...this costus should be able to flower in the pot as they grow to about 2 ft only...just have to wait for them to grow to the right size...

Hi Sweethalo,
U're welcomed. I think Plant 2 is costus malortieanus. I have it too. It's not easy to be sure because there are a few costus that look alike. but i think the leaves are more roundish compared to the curvibracteatus.

Wow ... thanks for the fotos... at least now I can look forward to the getting the flowers to bloom...

BTW, the flowers only bloom at the tip of each stem right ... so what happens after the bloom is spent, do u cut the whole stem away ot just the spent flower?

Is Plant 1 like the French Kiss costus?

I went to SBG yesterday and was amazed at the different type of costus... I thot the Plant 2 was the same as something they had at SBG with whitish flowers on a green bud... but at least deTengs' one is orangy...yippee....

Cheers :rolleyes:/>

normally i do not cut the whole stem. Costus stems last a long time even after the terminal inflorescence is spent. Hence, I do not touch the stem or inflorescence but leave them intact to help the mother plant build food resources for the next generation. I'll cut them only when they shrivel and dry up.
