Don't think they grow in the frozen tundra.

They grow in zone 5-10. You could overwinter the roots indoors and replant in spring. They are prolific and can produce the first year.

I only have a method for growing them from seed. Plant seed, waste your time attempting to grow them, use compost in a raised bed elsewhere in the garden, go plant some tomatoes there... you now have maypops 😁

That’s no joke, they’ve popped up all over. I’ve heard seed starting is tough but thinking a root cutting would be pretty successful given their aggressive nature.

This is my go-to for propagation methods. Also look up Norman deno for guidance on seed starting.

Thanks John. Does the text highlight the different methods for different plant family? Or is it a general how to guide?

Yeah the hardier one Passiflora caerulea gets everywhere here even after I have taken it out! With those root cuttings use some EM on it. If you don't have that just components of it e.g yeast or lactic acid bacteria from yogurt etc should help them form roots faster. I used some bokashi with biochar on some rose cuttings last year and they all took for once.

It's a reference with details for each type of plant. It also includes some general how to for different methods. I'll try to remember to get an example from it tonight.

I have it in my cart. I need a new read anyways.

Now that I did not know. The only place I have seen them is Hawaii. Maybe my zone 8 will work...

They’re native to the continental US. They’ll definitely grow where you are. If the root cuttings work out, I’ll start selling them for shipment.

No mention of root propagation.. sounds like this will be an experiment for academia.

Looks like AI has a pretty good answer. Yes, it is possible to grow **maypop (Passiflora incarnata)** from root cuttings, although it is less common than growing it from seeds or stem cuttings. Maypop is a vigorous perennial vine that spreads through its root system, and root cuttings can be a viable method of propagation if done correctly. ### Steps to Grow Maypop from Root Cuttings: 1. **Timing**: The best time to take root cuttings is in late winter or early spring when the plant is dormant. 2. **Selecting Roots**: Choose healthy, young roots that are about 1/4 to 1/2 inch in diameter. Avoid old, woody roots. 3. **Cutting Preparation**: - Cut the roots into sections about 2-4 inches long. - Ensure each cutting has at least one node or bud (these are small, bumpy areas where new shoots can emerge). 4. **Planting**: - Plant the root cuttings horizontally or vertically in a well-draining potting mix, burying them about 1-2 inches deep. - Keep the soil moist but not waterlogged. 5. **Environment**: - Place the cuttings in a warm, bright location (indirect light is best). - Maintain a temperature of around **70°F to 75°F (21°C to 24°C)** for optimal rooting. 6. **Care**: - New shoots should emerge in a few weeks. Once established, transplant the cuttings into the garden or larger pots. ### Notes: - Maypop is known for its vigorous growth and ability to spread via its root system, so root cuttings can be an effective way to propagate it. - However, stem cuttings or seeds are more commonly used because they are easier to handle and have higher success rates. If you're experimenting with root cuttings, be patient and provide consistent care to ensure success.

This is the hardest one I’ve seen

I am confusing passion flower with passion fruit. Passion flower is definitely hardy and grows well in western Washington. No fruit though.
