my standard of growing neps is much lower than many, so I actually am more easily satisfied.
Last year, did my first ever hybrid: mirabilis x gracilis, both being red form.
yes its a lousy cross, but the experience of growing out my 'home-made' plants is unforgettable. Just wanted to share pics of the hybrid, plain and small it may be, but the colour is certainly very nice.
Variation not much, there are some greener ones, but they are turning red with age too.
Hope you enjoyed them as much as I did.
