Having been absent for some time due to trouble with my IPad I started to go through all the 'unread posts'. Unfortunately I was disturbed and had to leave it but was about to reply to some posts about Ipomea alba. Back this morning and I can no longer find the correct page.......so will post my comments here under Ipomea which seems a logical thing to do although I notice my last post under this heading was about Coreopsis🤔
Anyway.... Ipomea alba....... this year has been very disappointing and I put it down to the extreme temperatures we have had throughout the summer.
I start my saved seeds early in the house ready for planting out as soon as night temperatures allow. I find the vines have to be quite mature before flowers start forming and eventually opening. In order to enjoy them more I put them in a pot in a different position to one used previously. The plants grew strongly and some flowering shoots appeared but before reaching any size they dried up and withered away. Finally when I had almost given up hope one flower opened....but others on the same stem keeled over and came to nothing as they approached fruition. The position I chose this year for the plants was in a slightly hotter spot but with some shade during the hottest hours . This, coupled with the unrelenting heat we had this year from June onwards, was the reason for my disappointment I think. My best results came when the plants were in almost permanent light shade. Some new flowering stems are appearing now and temperatures have dropped considerably and so I am still hoping for the odd late bloom but next year they will be going back to their original position.
