I had great success with this celery. Grew very tall and when I cut it, it regrew a bit before winter.

Utah Tall Celery

I have tried for a few years to grow celery without much luck. Until I tried Migardeners celery seed three years ago. I’ve had tremendous success with their seed.
The Utah celery grows beautifully once it’s past the early stages of germination. And the packet of seeds really go a long way.

good quality seeds with high germination rate

I've never grown celery before. So I tried these seeds. They take a long time to mature. I planted them in June after I had my sets sitting for several weeks. I have a spot I can use for cool loving plants in the summer. I really wasn't harvesting anything until September. But since late September I've been harvesting stocks every couple weeks using cut and come again. Here it is November. We've had several snow and frost days. It's been as cold as 22F. There's minor frost damage on the stocks. The leaves are perfectly fine. But the plant is still growing and producing. I'm sure it's slowing down. But I just harvested some recently and put it into some curry and it's got great flavor still. I'm going to see how long I can keep it going.

I do notice the stocks don't seem to be very big. But... I'm new to celery, so it could be more about how I'm growing it. I don't have it in the most ideal spot. So I wouldn't fault it yet. And for how I use it, it's just perfect size for me. I would plant 3 next year. 2 just wasn't quite enough.
