Has anyone any experience of raising Watsonia from seed please? After over two months I managed to get some to germinate but am unsure how to grow them on. The largest are now at the 6" single leaf stage and I now have five of these (waiting with baited breath for the others to emerge!) I'm keeping them indoors at present on a cool window sill - a precaution against the mollusc horde outdoors and possible late frost.
Any thoughts please?
I managed to get two to germinate which I got from the RHS seed collection. I kept them in the green house for about three years and then put them outside in pots for 1-2 years and I planted one of them late summer last year in a bed near the back door so I could see it from the lounge. This year I have 8 flower spikes showing. They are not in flower yet so I have no idea what colour they will be but I suspect its orange. They look very similar to crocosmia but bigger.
Hoping to get some seed to grow more and would be interested if anyone has watsonias with different coloured flowers.
