Actually I do come home with a trunk full quite often, most varieties I get at $0.70 with a freebie every 5-6 plants purchased.
Dutchlady, our soil is mostly loam, never gritty or sandy. That's why we have regular floods in the rainy season. Just a few hours ago we got 30 mins of torrential rain after a whole day of heat and humidity - and I'm talking lots of rain, wind and lightnng...and then nothing for the whole night. Google 'yolanda' if you want to get an idea how bad the typhoons get.
