I emigrated to the US in 1975.
The “Currys” emigrated in 1982 (illegally, Don’t tell Trump). and have been with us since then on the basis of “The Deferred Action for Childhood Arrivals (DACA) “. Two of them are 35 years old (Scientific name: Helichrysum italicum)
They go on summer vacation outside to the patio and invited indoors for winter. On Dec 25th 2017, the temp outside was about 20F (about minus 6C)!! Inside it was about a balmy 72F/20C. 2.5 inches of snow on the ground ! (can see the snow out of the window on the picture)
Before they come inside in fall / Autumn, they get a good shower including insecticidal soap. This is for prophylaxis. Regular insecticides are toxic to us. They are vulnerable to spider mites and scale indoors. In spring they are re pottedonce in 2 or 3 yrs.
They are very hardy. Even if they shed all the leaves indoors, they will bounce back in spring, much to our delight. One spring we threw out a plant which appeared dead in the pot. But, lo and behold, like the Phoenix, when it got warmer it started sprouting tender leaves! A “hard to kill” plant.
We have propagated many new plants arising from the roots. Very limited success with seed. We usually prune out flowers so that all the energy goes to foliage production. The flowers also have the characteristic aroma. We distribute daughter plants and leaves to family and friends. Sometimes the distributed plants die. We think it is not due to lack of care but they miss our tender loving touch and voice Without that, they get depressed and commit suicide!!~
It is nice to be able to pluck fresh leaves for cooking from the adjoining room or patio! The leaves add flavour to any curry, even the lowly “Pol Sambol” takes on another dimension!!
We in the temperate zone make so much fuss to keep them going. While I was in Florida, I found at Wimal’s, Devacaanthan’s and Johnpulle’s they have Curry trees and daughter plants growing around the mother like weeds. Reminds me of our home in Chavakachcheri, SL. Sam has a nice bushy pot for easy access on his patio. Sam is a good cook, I tasted his egg plant ( brinjal /obergene) curry, it was very good.
