That is a lovely colour, Heather.
How & where is your mum growing them? Mine were mostly in plastic half-pots mounted on some brick walls, but they got very very leggy (and top-heavy to the extent of pulling the plants out of the potting mix). Now we have had to cull one shade tree, they were baking a bit too much of an afternoon and I have lifted them down for the time being while I scratch my head. They certainly seem to flower better with more sun. Does your mum cut them back a bit or let them go wild?

Alison my mum and I grow the epis in buckets/pots or hanging baskets in the trees, safer from the snails and slugs.

The other friend I went to see has them in big containers about 50 cm high and wide, they are beautiful, he does have a big glass house not being used for tomatoes, to grow them in. A lot of his plants are not 'healthy' looking but he says as long as he waters them they do flower.....I think the biger the container the bigger they grow.

My mum's baskets have hardly any mix left in them at times she just adds bark or potting mix.

I have my last years seedling to repot I am not sure if I want to xpollinate them again as the seeds all seem to grow,and it seems to much bother.
