At my place, it grows and fruits well once established. I got two crops this year, one crop that ripened several months ago and I have another crop ripening now. My plant is severely neglected but it still gave me about 10-15 fruit with the early crop and it’s probably got about 10 or more Fruit hanging now.
The Frankie’s Red and the H Megalanthus seem to have similar growth rates and once they put on some size, they can grow and branch quickly. These two varieties are are especially good for home growers because they fruit later in the season and can hold on the vine for a long time. I’ve had Dragonfruit year round because Fruit left on the vine will stay good in my cold weather for months.
These two varieties also have thorns on the fruit which is bad for commercial growers but the spines are excellent for deterring critters from eating them.
