The next species up is the lovely Jacaranda mimosifolia. I have wanted to start these seeds for years and I'll finally get my chance. I ended up getting a ridiculous amount: 100 seeds. To be fair the pack only cost $2 so if anyone wants to trade for the extra seeds I may just have them!
When making my plant selections I generally look for trees that can be grown as bonsai. If you can grow a plant as a bonsai, it can clearly take some abuse and be trained to remain small. However Jacaranda is one tree that may prove a little more difficult. It doesn't like to remain small and when pruned often responds with vigorous vertical growth. This might be ugly for a bonsai but could result in a nice, densely stemmed larger plant. I have no idea if I'll ever see any blooms but my ultimate goal is to get my plants to flower.
People suggest soaking the seeds for 12-24 hours prior to sowing. Many sources state light as important for germination but I have also seen reference to buried seeds germinating. I noticed a posting in a forum suggesting the best temperature was found to be a consistent 25C in a Brazilian study. Overall the seeds should be easily germinated in any seed starting mix. I'll probably experiment and try burying a few, while keeping others on the surface.
The next species up is Colville's Glory (Colvillea racemosa).
These are probably my favorite trees ever - I have been slightly obsessed with them ever since them flower in Portugal as a little kid. In my experience they germinate pretty easily but I have never managed to raise them to the point of flowering.
ReplyDeleteThey are absolutely gorgeous. I've heard other people had difficulty growing them much past the seedling stage. I'll have to give them some extra care.
ReplyDeletethese are easy, and strangely enough, I had a grouping of three, grown as a bonsai! They behave better than you are thinking, and need trimmed three or four times a year, but not too hard. Mine froze when my greenhouse ran out of propane...and never bloomed, but they were only eight years old-I had high hopes! The fine foliage gives the illusion of a much larger tree. Winter defoliation for a couple of months if too cool, then fresh new growth as the days get longer.
ReplyDeleteYikes, I'd be devastated if I lost mine, especially after eight years! I'm glad to hear they should do better being trimmed than I expected. If I have any questions, I'll know who to ask.
