Hellebores 'Royal Heritage' strain sterile?
Amongst the four Hellebores plants that flowered for me for the first time this year was one plant from the 'Royal Heritage' strain.
While I was successful with hand pollinating between the three plants of the 'Sunshine' strain, the 'Royal Heritage' one didn't seem to work as either parent. First I found, that the anthers never got 'fluffy' to release pollen, but fell off before ever reaching that point.
Then I tried to use it as the mother plant and handpollinated with pollen from one of the 'Sunshine' strain plants. But while all my other handpollinations (each of them carried out three times on three consecutive days as described in the Rice / Strangman book) were successful, not a single seedpod developed on the 'Royal Heritage' plant.
Obviously no selfpollination or natural pollination had occured either.
Eventhough I bought my plant from Gardenimport I believe, that the strain originates from Wayside Gardens, where they obviously grow a lot of them.
Does anybody have suggestions on why this happened? Has any of you gotten seed from a 'Royal Heritage' plant?
Is it possible, that 'Royal Heritage' and 'Sunshine' strain don't hybridize? And why didn't my plant produce viable pollen?
It is a nice green / pinkish picotee and I would have loved to cross it with my dark purple 'Sunshine' plant.
Any comments would be very appreciated!
