Meet the Parents
I have been a collector of cacti for over 50 years. Although I like to have a representative collection, showing all the main forms, I have certain preferences.
One group I particularly like have the tubular flower type. The narrowest, most slender tubes are found in Cleistocactus, so-named because the stamens almost close the tube. Wider ones include Matucana and Hildewintera. These can be cross-pollinated to produce intergeneric hybrids. They can also hybridise with Echinopsis, Lobivia, etc.
On about 16 July 2019 I hand pollinated the Hildwintera hybrid Kleine Gelbe 2* (small yellow) with a pure white Echinopsis.
There was no other potential pollen donor open so any seed would be from fertilisation by the Echinopsis, or by self-fertilisation.
By 23 July the fruit was seen to be forming.
On 10 August I cut fruit open and collected 15 black seed plus some paler ones, all of which I set to dry.
I will be sowing those seeds today. If they germinate it will be several years before any flowers are produced.
