Xanthorrhoea Species, Australian Grass Tree, Square Leaved Grass Tree

I have propagated Xanthorrhoea Johnsonii from seeds collected from a flowering spear, I have 4 plants in my garden and 3 in pots and app...Read Morerox 80 seeds growing in Brisbane. I have not burned my plants or smoked them... they will put up a spear without this, I think they just need a good year...
So far this year I have propagated 80 odd baby plants from seeds...From two different Grass Trees.

These are great plants and I am having a fun time learning more about them!
Your options of when to plant the seed was not exactly right and you can find out what I did at the blog site. Cheers Carol

Xanthorrhoea arborea and X. macronema are drought-resistant but frost tender, while X. australis is frost-resistant ...Read Morebut not drought-tolerant. All require smoke from our bush fires to germinate the seeds; hence it is hard to progagate from seed without special equipment. Here in Australia it is MUCH easier to buy advanced plants for the garden.

This is a very slow growing plant highly sought after by collectors. There are about 30 species, but only 3-4 are found in culitavation ...Read Morein the US. They are very reminiscent of Dasylirion (the Mexican Grass Tree), Beucarnia/Nolina (also sometimes referred to as grass trees) and some finer Yucca/ Agave species. They have densely bushy crowns of long, stiff, slightly sharp-edged leaves that look a bit like yucca spines. Some have very attractive bluish leaves that make striking landscape specimens. The flowers shoot out the tops similar to the other plants mentioned above, and then dry as the sharp, triangular seeds develop by the thousands- the wind blows them and spreads them about (though, in the US, germination is extremely unlikely without help). Moving plants once they have established themselves is very tricky and usually ends in the decline and eventual death of the plant. This is important to know when buying imported caudeces from Australia (usually cost hundreds and hundreds of dollars)- they rarely survive!
