The seeds these beauties grew from,were kindly given to me by a very sweet friend & generous Dave's gardener..Kyle Courtney. If not for Kyle I would be without these treasured little beauties and my collection would still be close to a standstill. They have only started to bloom for me from late last year(our summer)onwards. All were under a year old but would have bloomed much sooner had I potted them into bigger pots much earlier that I did and had they been in full sun...for many months they only had a few hours sun per day.. I think Kyle mentioned somewhere that he has had Oleanders bloom at app 6 months...If you want them to bloom in the shortest time possible,my advice would be,and I am no expert by any means,give them all day sun/heat and good rich soil with plenty of moisture.
