I enjoyed the tour round the alpine house in your 30th July diary entry; it is amazing how much you can find to photograph at this time of the year.
In the background of the third photo (the one with the campanulas), there is a white bulbous plant flowering. Is this a species of Pancratium ? Do you have a close up of it you could post ?
Well spotted! - yes this is Pancratium maritimum. It was the first time this had flowered for us but sadly I did not get round to taking a picture before it had faded. Let's hope it flowers again next year so I can rectify that.
How did you get Pancratium to flower? I have had it for years and never a flower. I always thought it must need a baking in the summer as I've seen it on the coast in the Med, growing in pure sand with the bulbs on the surface. But, it's not as if it's been a hot summer this year! What's the secret, please?
I'm sorry I didn't get to see it. It's been a while since I've had time to visit. I'd like to echo Diane's request; I have also grown this bulb for several years without flowers.
What a delight to see the pictures of Sempervivums in the Alpine House, they always have some interest even when other plants are not doing a lot.
What I particularly liked, was the comments on Pancratium maritima. I collected seed from a beach in Northern Spain, some years ago, and grew the plants for a few years. Unfortunately, I did not look after them properly and they did not survive. However, if I can ever get some more seed I would love to have another go, they germinated quite well. The real problem is flowering, I would echo the other comments, how do you get them to flower?
This was the first time we had flowered the Pancratium, so I'm not sure we have a "secret" to share. It is in a house which gets very hot in summer, so heat may well be a factor. It is also desperately in need of repotting, so maybe a cramped pot played a part?? - although it is in a sand plunge and the roots come out of the bottom of the pot giving it in effect a free root run! The question will be can we flower it again next year??
