Papalo days to harvest

Papalo is an ancient herb that is commonly grown and eaten in South and Central America but is practically unheard of here.  Finding seeds of this amazing herb in Australia was far more difficult than I had imagined.

Papalo has a unique and intense taste, it is often used as a substitute for coriander leaf but they taste different.  Young papalo leaves are mild and older leaves are more potent.  I love the taste of papalo, it is one of my absolute favourite edible herbs.

Unlike coriander, papalo grows well in the heat of summer.  It is said to be drought tolerant, but mine wilts badly on hot days and picks up nicely after it gets a bit of water.

There is a bit of confusion over the binomial name, I a told they were Porophyllum coloratum but there is a chance that they may be a different form of Porophyllum ruderale.  Until I am a little more certain I will only list the genus.

I planted two batches of seed, both had dreadfully low germination rates, which is meant to be common in papalo.  Papalo grows vigorously and its smell/taste is remarkably strong so you only really need 1 or 2 plants.  This summer was incredibly harsh so these days to maturity may not be representative of an average year.

These died off before the first true leaf stage so I planted another batch. I think heat/sun killed them.  I gave the second set of seeds protection from the afternoon sun, and they fared much better.  In a less intense year they would do fine with full sun, but this year we skipped spring and went straight from winter into a raging summer which isn't great for small seedlings.

Harvest start         22/12/2019      Day 51
Flowering             28/03/2020       The growing conditions are not ideal, I assume they should flower earlier than this

I started to harvest earlier than I should, but I couldn't wait to taste papalo.  I am guessing a decent harvest would have started around day 80.
