June 2002 - here's a second plant which was kept in a greenhouse when the other plants above were killed by winter cold. This plant was planted out in the spring of 2001 and survived the winter of 2001-2002 (warmest on record at Providence, so what does that say??). It was also protected by moisture with a poly roof during the winter. Here it is flowering in May. The low temp it survived was about 12F. |
