A Hardy Agapanthus

This is my third year with Agapanthus 'Blue Yonder' in the open garden. It started with a small shoot overwintered in the garage and then the next two winters in the open garden unprotected. We were down to just below zero with little or no snow cover and a heavy, wet soil and it doesn't seem to mind.

Maybe next year I'll have a few more bloom stalks, the side shoots seem to be bulking up this year.

    I have a 'blue yonder' this year from Santa Rosa Gardens, but haven't plunged it into ground (was a July order during their clearance). It's a three or four head plant in a 4 inch pot. I'm z7, would you plant it or keep it indoors for the winter?

    Was so glad to see someone having success with the plant!

    How tall is the leaf rosette, wondering where I can not bury it in surrounding plant foliage too much (lol).

    I have veronica Sunny Border Blue. It's a wonderful plant, blooms all season, I've deadheaded it twice this summer and it always bounces right back with lots of bloom.

    Mine was also from a Santa Rosa summer clearance sale! I kept it on a non-freezing garage windowsill for the first winter (leafless and dormant) watered and gave it a little more light once it started growing, and then planted it outside.... not much deeper than it was growing on the pot. I bet you could just plant it out now and be just fine, I’m sure there’s still plenty of time for it to settle in.

    I love mine. I went so far as to run down a seed source for Agapanthus Campanulatus (which I think I’d what this is) so I can try a few run of the mill seedlings outside as well. The parent plants have been outside in z6 for several years doing just fine.

    I have 2 different Agapanthus planted in my yard. One said it was hardy to zone 6 (which I am in ) and the other one not as hardy. I have them both planted on the side of my east facing garage (so probably a warmer micro-climate as I also have gladiolas that come back too in the same area) and both have come back for many years now. I wish I had kept the tags so I would know the names. I used to mulch them with leaves but I quit doing that a few years ago and just left their own leaves as winter protection and they are doing just fine. Mine bloom in July and I love the color they provide!

    This is one of those plants that loves neglect, not coddling. Mine, in a pot, never bloomed. This year it was on the side of a garage (out of sight, out of mind, no watering, feeding etc), and it bloomed!

    Hmm, that's good to know..there's a lot of plants that prefer benign neglect.

    Interesting.

    I lost at least two Agapanthus in January, 'Balmoral' and a supposedly high elevation collection of A. campanulatus sold by Seneca Hill in her final or penultimate year. (there might be a third in another part of the garden, but I can't remember if it was still around last summer or not)

    Read somewhere else that 'Blue Yonder' was very hardy, so want to try it now.

    Yes, I had one of those from Ellen at Seneca Hill, lost it immediately (sigh)...I keep trying too :)

    I had really good luck with most of Ellen's plants, despite a tendency for them to be newly divided/potted.

    I usually do very well with the plants that thrive on benign neglect. I have nothing but high hopes for this plant now!

    I inadvertently bought a deciduous Agapanthus 'Sandringham' a few years ago, here where cold hardiness is a non-issue, and it has grown but never bloomed. The usual non-hardy kind here grow and bloom like weeds. That 'Blue Yonder' is a beauty!

    I need a agapanthus that is more xeric. They bloom less often that they don't bloom. I guess I should take better care of them.

    "They bloom less often that they don't bloom."

    Oh don't worry, that happens in other climates besides Texas.

    The tender ones need a truly mild climate like LA (watered) or Sydney, but bloom for a very long time there.

    The high elevation South African ones probably bloom longer in a place like England where the cool nights help create a vernalization effect. Here they are over in a flash most years. This is the problem I had with Dieramas - most years they would just not bloom at all, even if they had become a big healthy looking plant. Nights too warm in summer. The January 2018 freeze wiped out the last of them anyhow.

    I tore mine out after years of no blooming and then one came up and bloomed years after the eradication. We will see if it does it again. Not this miserable year.
