Astrophytum Hybrid Collection
For the past four years I have been growing seedlings from astrophytum hybrid seed. I have selected some of the more attractive types, with the hope of cross pollinating them to produce even nicer plants. I didn't want to trust them spending the winter outside in the heated frames, http://stewart723.blogspot.com/2013/11/succulent-winter-quarters.html where I over-winter most of my plants. Instead, I am over-wintering them inside the house on a shelf near a south facing window. Many of these should flower next year and I will cross pollinate them and sow the resulting seed.
Haworthia truncata Collection
I grow quite a few haworthias, but my favorites are H. truncata. I have recently been growing them from seed I obtain from my older plants. I didn't want to risk these in the outdoor heated frames, so they are also in the house on the shelf in the south facing window. Although they don't get as much light as they would outside, at least they are available for me to work with over the winter. The haworthias will often produce flowers in late winter and I'll cross pollinate some of the plants and hopefully get fruit and seeds.
