    Prompt, honest service

    I was very satisfied with service. Original seeds did not germinate so they sent me new seeds. They did germinate. Very satisfied with Pinetree Garden seeds.

    Fabulous Vines

    I don't have any flowers yet, but the vines are growing beautifully and are pretty by themselves. I hope I get flowers soon, but I think I planted them too late.

    Perennial sweet pea

    As always service and shipping times were great. I've been growing perennial sweet peas for years and thought it was time to expand on the two vines I've had over 6 years.

    No luck with these--

    I just can't grow these--maybe it's me, but all I get is spindly vines and they don't come back.

    Sweet Pea perennial seeds

    I'll need to wait until next year to start the seeds...they should be a decent height before putting in the ground, but I look forward to their beauty! Good service..thanks and blessings, Linda
