I'm growing Red or Pink Oxheart tomato seeds, this year. I was told they were Pink Oxheart, initially, but the label said Red Oxheart, and the fruits were also red, I was told (we shall see). This variety came highly recommended by Mumsey of the Organic Gardening Community.
Here's my plant, this year. This picture was taken on 27 May 2020.
Here's my plant on 23 June 2020. It set fruit by that date. It doesn't seem to be wispy, for an oxheart. It's curling, but that's probably temporary; tomatoes do that sometimes in the evening when the UV index was high earlier in the day; it was 10 earlier on this day).
