Bought our dragonfruit about a year ago. It's the Purple Haze variety. Made a trellis for it. It initially grew like crazy. It will continue to grow the more trellis space is provided. Tied it to trellis with panty hose. It just got its first flower. Looking forward to the fruit. Grows great in South Florida.

Southern California Lowe's is selling Hylocereus polyrhizus.
The potted plants are about 20" - 30" tall and are in 3 gallon pots.
What was surprising to me is the plants had a fancy colored printed pot sleeve with additional information on the inside.
I will post some pictures of the plant I bought and the labeling.

Have had this plant for over 10 years and gotten many starts off it, but none have ever bloomed!!! I've tried everything..any suggestions? I'm in zone 9b. I have similar plants that have bloomed nicely and regularly. This one is a puzzelment to me. Not giving up...it is a heirloom plant.

Any advice would be appreciated.

we bought one in South Florida on a vacation and brought it back to Houston this summer. Since May, it has already grown over a two feet. We have it climbing on a trellis and planted in our cactus garden. It is on the East side of the house and gets good morning sun until about 1:20pm. Can't wait to get fruit from it.

The Hylocereus genus has No leaves or Foliage, therefore propagation is from stem cuttings and seeds.

Fast grower. Buds begin to open mid-day. Blooms last for about 24 hours. Flowers are large (6 in. diameter x 10 in. height) with insignificant fragrance.

This plant is great.. I planted him about 1 month ago, on a south facing wall, with a little Dr. Earth in the soil.. He has 3 new shoots growing, i hope i get some fruit this year. Snails are a problem so be sure to put out snail bait if u want a nice looking plant. Dont over water, but fertalize with a high middle number, once a month, 10-60-10 is good.. No pest's noted..
