Some one who should know better ID's Tom's plant [the parent of mine] as Bomarea boliviensis.
As far as I know Bomarea boliviensis is not in cultivation [all the pictures on the web are Alstroemeria isabellana].
Plants from seed from Dan Hinkley's plant came to the UK via Crug under that wrong name.
That plant is Alstroemeria isabellana which is a widely variable species [see for example the forms at
Brazil Plants ]. The form we all have via Crug is being called 'Fred Meyer' and comes true from seed. It looks like this;
Far Reaches Farm explain the Fred Meyers link like this;
'We got this from Maggie at Western Hills some years ago and finally can offer this goody. She said this was a hybrid by noted California breeder Fred Meyer between the vining Bomarea and the non-vining Alstroemeria and we have sold it in the past as Alstroemeria x Bomarea 'Fred Meyer' and more recently as Bomarea "Fred Meyer". The great thing about putting a plant on the internet is that all sorts of smart people read about it and very nicely suggest the correct name. This is a surprisingly hardy Brazilian species and Fred Meyer collected in Brazil quite extensively. Good cut flower with long clean stems. We've had this growing happily outside for years and going through single digits in winter with mulch.'
The plant I have shown above is Tom's wild collection and is a Bomarea that is 'erect' and non climbing.
I can classify down to the section of the genus with confidence, but the species is speculative.
It is a Bomarea from section Wichuraea, and the speculative species is Bomarea dulcis.
I would have been selling Alstroemeria isabellana 'Fred Meyer' at Tregrehan last week were it not for the plague!
