Lettuce- Grand Rapids TBR (Heirloom)
Lactuca sativa
Grand Rapids TBR, a vibrant loose leaf lettuce with light green leaves and a slightly white center, grows rapidly from Fall through early Spring. It was developed in Grand Rapids, Michigan, to handle the cool or warm, damp, and low light conditions that the lettuce would endure in the shipping process. Now, what the heck does that have to do with growing lettuce in Florida? Don't ask me why I tried this one out. I don't remember. Turns out, that in making this lettuce more robust for packing and distribution, they developed a lettuce that can handle our bi-polar winter weather. In addition, if you or a house member is on "team Iceberg", first off, my condolences. Grand Rapids with its light, crisp, clean taste, makes a great substitute.

“All items arrived quickly and well packaged. I usually expect to have one or two live items out of a batch, but they are all thriving. I couldn’t be happier!”

“My live plants were packed like they belonged in Ft Knox. 😂 They really were packed beautifully. Only one plant, a bee balm, is questionable but signs that it will recover are happening. All in all I am thrilled with my plants and seeds. Some of my coreopsis have already sprouted!”

“I’ve ordered seeds from Whitwam Organics 3 or 4 times now. I love the simple packaging, clear planting guidelines, and variety they offer. Great germination rates!! The bare root plants I’ve ordered have come healthy, so healthy that the wild rabbits always approve of my menu upgrades! 😂🐰”
