Flavour-wise I liked it, but it is more of a bitter type of lettuce. You won’t notice it depending on what salad dressing you use. But on its own you will absolutely notice it. (Less bitter than spinach, but you will notice it.) It also has some depth of flavour to it, so it tastes better than others.
True to the description, it is very compact. It germinated well for me and tolerated my poor fall soil.
Tried this on a whim and I’m happy with the results.
It has a lovely mild floral flavour, and it’s also not bitter.
I normally use a catalina dressing for salads, and it goes really well with that. I think it could go well with a sweet apple or kale salad too. But it definitely is a small addition to a base big leafy salad. The match leaves are small and do better when mixed with another type of leaf.
I can’t comment on germination rate or cold hardiness (posting this in Oct zone 5, and my garden bed soil is not amazing).
I grew this one year earlier and was my first time growing broccoli so I feel I made a good choice, there was a good return, nice sized heads and of course the novelty of purple. I started them really early as transplants for success, and they were done in July. If you're going to grow broccoli, grow a F1 variety , the purple is a bonus.
