WS Tall Garden Phlox?

16 years ago

A Question:

Is Tall Garden Phlox the one called "paniculata"? Does it usually give sterile seed, or is it able to start from seed? I'm interested in perennial types (just in case all of them aren't perennial). I'd like to get seed and WS some next year, but I'm not finding much seed for tall varieties, only bareroots and plants.

I think it does reseed to some extent but reverts back to the species color - purplish pink which I find rather pretty also. Not sure about all the new specialty colors if they are sterile or not....

Linda,

I tried winter sowing some a few years ago but I wasn't successful. My Phlox Paniculata - and yes, they are perennials - used to just spread from the base.

Having said that, I have been amending the soil and in the last couple of years, they have reseeded. I realized in 2005 that is what they were doing, so in 2006 I left some reseeders of 'David' (the almighty white one), and Laura (A purple/white) to see what would grow. The leaves are true to the parents. David reseeders are light in colour (leaves) and the plants are as vigorous as the parent. I should see some blooms this year if my dog keeps the deers away as she has been.

So basically, if they reseeded here, then they can be winter sown. Maybe they need a full winter and the reason they didn't winter sow successfully for me was that I do most of my wsing in late Feb and March through April.

Worth a try!

That's it!...and in checking my Indiana Wildflower book, I see it is a native here and ranges in color from red purple to white. Would this one maybe be referred to then as 'species' Phlox paniculata? I know there are many named varieties of it. Sue

I like the look of dead plants and evergreens in the winter, but if you don't you can certainly cut them back whenever you like and you will not hurt the plant one bit. They are tough plants and completely hardy so cover them or not, it is up to you but likely not necessary. I assume they were still green when you planted them? If they made it through the transplant cutting back the stalks now won't impact either way. You did not need to cut them back at planting though doing so by half is what some folks do to minimize transpiration and the plant mass that the reduced root system must support...but I doubt anyone would tell you you SHOULD have done so.

Varmints! I had voles take out one clump of my purple phlox last week. Dig down carefully and see if the roots are intact. It might be a disease, but most likely some kind of rodent. They have a decided sweet tooth. Phlox and roses are sweet through and through and voles love their roots. They will also eat tulip bulbs. I plant daffodils around my tulips for protection. Daffs are poisonous, so the voles leave them alone. Little buggers! Whatever is causing it, I sure hope you discover it soon. Solution for your phlox? Bury roofing paper down in the ground around their roots or a bottomless black plastic pot. Use one big enough to accommodate their root ball size so you don't cramp their growth. The rodents will dig through the earth and run smack dab into that and go around it. That is the only thing that has ever helped me save mine. ~Annie

Thanks for the info, Lynne and Tiffy :-)
I'm going to look at my options and figure out what I'll do. I did get a gift certificate to Lowes from my husband for my birthday (boy does he know me :-), and I might be able to pick up a plant or two cheaply, as things start winding down in garden centers this summer.

I wintered them on 12/16 and by June 5th I tossed them out. Maybe I'll be surprised next year LOL!
