I grow several dwarf ones (not the variegated one as it became a weed in my garden as did the aurea one) which thrive over autumn (fall), not bad over winter, and thriving again in spring. Over summer there is a bit of a show. Mine are in full sun. This year bought a very dark one which is called Inticancha Temple of the Sun- dark purple. I tried to keep it in the pot but it got smaller and smaller, so put it in the garden, not in a full sun place, and it is going mad. Of course this is a warm climate. I guess if I put mine more in a shady position, they would be happier over summer too. My guess is that it would not be the heat so much as that they do not do well in pots. Their roots would have to be cool, at least that is my impression. Ina On 2/06/2012 5:07 p.m., Jtlehmann@aol.com wrote: > How well do the Rock& Roll Alstoemeria perform in the long run?
