Re: Drosera and some extremely rare tuberous
 

So sad that we won't be able to grow them in the tropic. :sad:
Mind to tell how you keep them during winter? And why do they require cool winter to thrive? How the plant react or look like during winter? Sorry, so many questions. :tongue:

Re: Drosera and some extremely rare tuberous
 

grandmaster,

I echo what everyone else is saying... Your plants are simply beautiful. Can't get my eyes off D. lowrie and D. zonaria. So unique and beautiful. Can give a little explanation on how you grow them and what is their requirement? Thanks

Re: Drosera and some extremely rare tuberous
 

Reqirements are simple

Soil: 50/50 peat/sand
light:lots of
water:lots of when they are growing and when they die back ease of the water untill they are dormant, when they are dormant no water what so ever.

Because they are Tuberous Drosera they are from W.A. they are temperate plants that require seasons to indicate growth, flowering, dieing back ect. They grow during the winter in W.A. because the summers here are hot and dry and the winters are cool and wet, they go into dormancy during summer so six months of the year you see no growth past the soil surface.

I have been trying to germinate a batch of D gigantea seeds since March. Looking forward... fingers cross. After what I have read above. I am still hopping.

Re: Drosera and some extremely rare tuberous
 

You should re-read that.

You are Wasting your time, you can't grow Tuberous Drosera in the tropics.

Re: Drosera and some extremely rare tuberous
 

Thanks for the warning, Grand. Well, since the seeds are here might as well try. No harm just filling water into the tray once a week.

Re: Drosera and some extremely rare tuberous
 

Great photos, I have not seen some of these species myself.
Other thing about tuberous sundew seeds, many WA species need special techiques to get germination. Put simply they need a bushfire. Reasons are several the fire clean the overhead vegetation, produce fertilzer (ash) and release chemicals in smoke which trigger germination. On top of this it can take three years for germination.
Good news is some species such as gigantea do not need the above conditions. Other species are to easy germinate from personal experience(if you live in a warm temperate area) are auriculata, peltata, macrantha ssp planchonii, stolonifera ssp stolonifera, ssp rupicola, mooreii, whittakerii ssp whittakerii.

Re: Drosera and some extremely rare tuberous
 

The chemical needed to induce germination is called Ethylene. Drosera stricticularis is another species that self pollinates and germinates easily. Found in Western Australia and Port Lincoln in South Australia.:1thumbup:

Re: Drosera and some extremely rare tuberous
 

Drosera mooreii, stolonifera and whittakerii ssp whittakerii need two genetic parents for seed set, mooreii will set a small amount of seeds with pollintion between clone sisters.
I think there is several chemicals release by the gum trees also involed, with some non CP natives, heat itself.
I have seen the SA version of the stricticularis in cultivation, once. An ACPS member from Port Lincolin brought pot in several years ago. It smaller in all parts than it WA counterpart. It found in one swamp south of the Airport. He reported it took 5 years to reach heigh of about 11cm. I have heard a rumour of Drosera ramellosa in the very tip of Eyre Peniusla.
Anyone got seeds of stricticularis ?

Re: Drosera and some extremely rare tuberous
 

That explains why my tubers seeds have not germination even after almost half a year. Guess we could just admire the picture from you guys living where they grow. I do hope somebody here in the tropics would try the suggestion by Khoas in his other thread "Tuberous Drosera in the Tropics".
