well they are certainly from a something like Ixias or gladioli. Usually 3 years to get to flowering size. depends if you want to wait or not.

They do self seed, and I found it is worth letting them grow as recessive genes appear, sometimes better than the parents.

I've only got 2 red Ixias. Are they rare or something? I'd really like more red ones.Thank you for your replies. I'm going to let these grow on & see what transpires.

depends on the genetics that makes them red. Many colours involve several genes and then usually each gene has 2 ways of being expressed and it is the combination of these that determines colour.
