Manitoba, Heirloom Tomato Seeds

Manitoba, Heirloom Tomato Seeds — The Canadian Prairie Slicer Built for Short Summers

Manitoba was developed at the Morden Experimental Farm in Manitoba, Canada, specifically to ripen during the short summers of the Manitoba prairie — and it delivers. A vigorous determinate variety, Manitoba bears heavy yields of 3–4 inch, 6 oz, slightly flattened bright red fruits with a refreshing, tangy tomato taste that is excellent for slicing or canning. One of the more productive early heirlooms available, Manitoba is an exceptional choice for northern areas including Montana, the Dakotas, and Wisconsin, and is perfectly suited for small gardens where space is limited but flavor is non-negotiable.

Determinate, 66 days. A proven Canadian heirloom with genuine cold-climate credentials.
