    2 questions:

    (1) These flowers look so beautiful! I need more yellow in my garden! Where are these flowers available to be purchased in Calgary, Alberta? Which gardening center businesses carry them? I would like to purchase some of them!

    (2) I understand that a person can sell bulbs from Florissa to help benefit a project.
    Is this only for schools to do?
    What about for my project?
    (a) I retired from teaching grade 1 in the fall of 2008.

    Shortly after I retired I raised funds to sponsor elementary, high school and university students to get an education. Many students received a good education which I would not likely to receive without our help. Now I helping a mother (one of my students in Belize who has an
    8-year old son. He studies hard and now ranks 2nd in his grade at school. She is not well and I have helped her with daily living expenses and also medical bills. Is it possible for me to see bulbs from Florissa to help with fundraising for this worthy family? I know of many people who I feel would be
    happy t contribute through purchasing flowers for their garden.
