I haven't had any success with Phlomis russeliana. They have been planted for two years and have never flowered.
They are in raised beds in soil enriched with both commercial and garden compost. They have afternoon sun only. Can anyone advise me? Thankyou



Hi, P russeliana canstand some shade, in fertile, well drained soil, in that position, I can't think of any reason why it doesn't flower, Derek.

Thanks Derek, I'll just have to see if they flower next year.

I'm just wondering if the soil is actually over rich for them - these grow wild in Turkey in free draining, sunny hot spots, and I'm pretty sure the soil's not that rich in nutrients. Some plants respond to high humus levels by just growing leaves and not flowering, so don't add any more 'good' stuff to the ground next year and see what happens.

Do you think they would prefer sandy soil? If not, I'll do as you say and neglect those areas when I'm adding compost or general fertiliser. I did use tomato food this year but perhaps that was the wrong thing to do.
Thanks for your advice Bamboo.

They like loamy or sandy or gritty soils, they do not like heavy clay - it needs to be free draining. It's worth a try, not adding compost and certainly not feeding them next year, and if that doesn't work, either the soil's too heavy or they're just not getting enough sun.

Thanks again Bamboo.
