I have been growing these hybrids for a at least three months *and it seems they are adapting really well. I'd say it's more of an intermediate plant having the ventricosa X (lowii X macrophylla) backgrounds.
i would like to show you that regardless the maternal background (mother plant), the progeny (seedlings from the cross) can carry either parent's looks (phenotype)
In general, the mother plant from any cross may be more influential on how the seedlings look like, but it does not mean that all of the seedlings will carry more of the mother than the father's genes.
This is, unless these two seedlings are of two different crossings.
